Back in late May of 1983, four members of the Lancaster County Bird Club—Russ Markert, Harold Morrrin, Steve Santner, and your editor—embarked on an energetic trip to find, observe, and photograph birds in the Lower Rio Grande Valley of Texas. What follows is a daily account of that two-week-long expedition. Notes logged by Markert some four decades ago are quoted in italics. The images are scans of 35 mm color slide photographs taken along the way by your editor.
DAY FIVE—May 25, 1983
Bentsen State Park, Texas
Went to bed last nite about 11:30. Did not set the alarm. Very hot — Awoke at 7:30 A.M. We circled the campground and then drove to the river trail. We walked to the river, getting more lifers for Larry — Couch’s Kingbird, Olive Sparrow, and Groove-billed Ani. The Couch’s Kingbird is my first lifer of the trip. The Olive Sparrow has the same cadence as the Tennessee Warbler. We then checked the resaca and found a Least Bittern.
While checking out the cattails at the resaca, we failed to catch a glimpse of a Coues’ Rice Rat (Oryzomys couesi), a semi-aquatic mammal that lives only in the Rio Grande Valley and areas south into Central America. Instead we found an Eastern Fox Squirrel (Sciurus niger), a giant compared to the gray squirrels in Pennsylvania. Things really are bigger in Texas.
This Couch’s Kingbird (Tyrannus couchii) was a “lifer” for both Russ and your editor; neither of us had ever seen one before. (Vintage 35 mm image)
Back to our camp site for lunch, after paying for our stay at the office. P.M. — Put out corn and sunflower seeds and loafed all P.M. trying to get pictures. Larry had a lot of luck. I did not do so good.
Plain Chachalacas, White-winged Doves, White-tipped Doves, Great-tailed Grackles, and a Bronzed Cowbird stopped by to sample the seed offerings. The chachalacas and grackles created quite a racket. It’s a good thing we didn’t have any neighbors close by!
Great-tailed Grackles visit Russ’ makeshift feeding station. These giants are 50% larger than the Common Grackles with which I was familiar. Yes, even the blackbirds are bigger in Texas. (Vintage 35 mm image)A Bronzed Cowbird picks up some seed morsels. (Vintage 35 mm image)
In nearby areas of the campground there were many species—Black-bellied Whistling Duck, Anhinga, Great Egret, Common Gallinule, Turkey Vulture, Yellow-billed Cuckoo, Golden-fronted Woodpecker, Ladder-backed Woodpecker, Eastern Kingbird, Brown-crested Flycatcher, Curve-billed Thrasher, Long-billed Thrasher (Toxostoma longirostre), Altamira Oriole, and Northern Cardinal.
A Golden-fronted Woodpecker peers from its nest cavity. (Vintage 35 mm image)The two thrasher species found in the campground highlighted the mix of two unique habitats. The Curve-billed Thrasher is a species of scrubland while this Long-billed Thrasher is more typically an inhabitant of bottomlands. (Vintage 35 mm image)
Rain is rare here — The rainy season produced no rain. Now a light rain is falling. The temperature dropped to 90° in the camper. One couple wanted to see anis. Larry picked one out 50 ft. from their campsite.
The Groove-billed Ani (Crotophaga sulcirostris) is a large-billed relative of the cuckoos. Because it is totally black in color, it can be very difficult to spot among the dense foliage where it typically feeds. It ranges north from Mexico only into south Texas. (Vintage 35 mm image)
The rain cooled the air to make the evening tolerable, but we would pay for it tomorrow with an increase in the humidity.

We paid for another nite and at dusk went to the Elf Owl tree where eventually 4 young came out and tried their wings and crawled around. The two adults flew in and Larry was ecstatic taking pictures with his strobe light. We met some people. One couple never saw Eastern Bluebirds. I gave him my card. Another couple pinpointed the owl tree.
This evening was certainly highlighted by the emergence of the young Elf Owls (Micrathene whitneyi) from their nest cavity. But in addition, we again heard the sounds of some of the other nocturnal birds found in the park—Common Nighthawk, Common Pauraque, and Eastern Screech Owl.
The Elf Owl is a species of desert bottomlands and canyons throughout southwestern portions of the United States and northwestern Mexico. Bentsen-Rio Grande State Park and the adjacent areas of Hidalgo County, Texas, are about as far east as they get. Look closely and you may discern two juveniles emerging from their nest cavity in a large tree. (Vintage 35 mm image)Juvenile Elf Owls checking out the visitors.

DAY FOUR—May 24, 1983
“AOK Campground—South of Kingsville, Texas”
“Arose at 6:30 A.M. to the tune of Common Nighthawks. After breakfast, we headed for Harlingen. While driving south we saw six pairs of Black-bellied Whistling Ducks. At Harlingen we phoned Father Tom, who is an expert birder for the area.”
As we drove south to Harlingen, much our 100-mile route was through the Laureles division of the King Ranch, the largest ranch in the United States. It covers over 800,000 acres and is larger than the state of Rhode Island. The road there was as straight as an arrow with wire fences on both sides and scrubland as far as the eye could see. Things really are bigger in Texas.
Once in Harlingen, we did two things no one needs to do anymore:
Find a coin-operated telephone to place a call to Father Tom.
Ask Father Tom for the latest tips on the locations of rare and/or target birds.
Today, nearly everyone traveling such distances to find birds is carrying a cellular phone and many can use theirs to access internet sites and databases such as eBird to get current sighting information. Back in 1983, Father Tom Pincelli was a dear friend to birders visiting the Lower Rio Grande Valley. Few places had a person who was willing to answer the phone and field inquiries regarding the latest whereabouts of this or that bird. To remain current, he also had to religiously (forgive me for the pun) collect sighting information from the observers with whom he had contact. For locations elsewhere across the country, a birder in 1983 was happy just to have a phone number for a hotline with a tape-recorded message listing the unusual sightings for its covered region. If you were lucky, the volunteer logging the sightings would be able to update the tape once a week. For those who dialed his number, Father Tom provided an exceptionally personal experience.
Since 1983, Father Tom Pincelli, also known as “Father Bird”, has tirelessly promoted birding and conservation throughout the Lower Rio Grande Valley. His efforts have included hosting a P.B.S. television program and writing columns for local newspapers. He has been instrumental in developing the annual Rio Grande Valley Birding Festival. The public sentiment he has generated for the birding paradise that is the Lower Rio Grande Valley has helped facilitate the acquisition and/or protection of many key parcels of land in the region.
“After receiving information on locations of Tropical Parula, Ferruginous Pygmy Owl, Hook-billed Kite, Brown Jay, and Clay-colored Robin, we went on to check out the Brownsville Airport where we will meet Harold and Steve Thursday noon.”
If we were going to see these five species in the American Birding Association listing area, then we would have to see them in the Lower Rio Grande Valley. All five were target birds for each of us, including Harold who had few other possibilities for new species on the trip. Father Tom provided us with tips for finding each.
I noticed as we began moving around Harlingen and Brownsville that Russ was swiftly getting his bearings—he had been here before and was starting to remember where things were. His ability to navigate his way around allowed us to keep moving and see a lot in a short time.
In Harlingen, we easily found Mourning Doves and the non-native Rock Pigeons, species we see regularly in Pennsylvania. We became more enthusiastic about doves and pigeons soon after when we saw the first of the several other species native to south Texas, the diminutive Inca Dove (Columbina inca), also known as the Mexican Dove.
“Next, to the Brownsville Dump to see the White-necked Ravens — Then to Mrs. Benn’s in Brownsville for the Buff-bellied Hummingbird. Both lifers for Larry.”
For birders wanting to see a White-necked Raven in the Lower Rio Grande Valley, the Brownsville Dump was the place to go. With very little effort—excluding a trip of nearly 2,000 miles to get there—we found them. Today, birders still go to the Brownsville Dump to find White-necked Ravens, though the dump is now called the Brownsville Landfill and the bird is known as the Chihuahuan Raven (Corvus cryptoleucus).
Mrs. Benn’s home was in a verdant residential neighborhood in Brownsville. She welcomed birders to come and see the Buff-bellied Hummingbirds that visited her feeder filled with sugar water. I don’t recall whether or not she kept a guest book for visitors to sign, but if she did, it would have included hundreds—maybe thousands—of names of people from all over North America who came to her garden to get a look at a Buff-bellied Hummingbird. After arriving, we waited a short time and sure enough, we watched a Buff-bellied Hummingbird (Amazilia yucatanensis) sipping Mrs. Benn’s home-brewed nectar from her glass feeder. This emerald hummingbird is primarily a Mexican species with a breeding range that extends north into the Lower Rio Grande Valley of Texas. When not breeding, a few will wander north and east along the Gulf Coastal Plain as far as Florida.
Other finds at Mrs Benn’s included White-winged Dove (Zenaida asiatica), Ash-throated Flycatcher (Myiarchus cinerascens), Brown-crested Flycatcher (Myiarchus tyrannulus), and Black-crested Titmouse (Baeolophus atricristatus), a species also known as Mexican Titmouse.

The Lower Rio Grande Valley from Rio Grande City east to the Gulf of Mexico is actually the river’s outflow delta. At least six historic channels have been delineated in Texas on the north side of the river’s present-day course. An equal number may exist south of the border in Mexico. Hundreds of oxbow lakes known as “resacas” mark the paths of the former channels through the delta. Many resacas are the centerpieces of parks, wildlife refuges, and housing developments. Still others are barely detectable after being buried in silt deposits left by the meandering river. Channelization, land disturbances related to agriculture, and a boom in urbanization throughout the valley have disconnected many of the most recently formed resacas from the river’s floodplain, preventing them from absorbing the impact of high-water events. These alterations to natural morphology can severely aggravate flooding and water pollution problems.
The Lower Rio Grande Valley is the site of a boom in urbanization. Undeveloped private holdings and government lands including numerous parks and refuges provide sanctuary for some of the valley’s unique wildlife. The parcels colored dark blue on the map are units of the Lower Rio Grande Valley National Wildlife Refuge. (United States Fish and Wildlife Service base image)
“On to Santa Ana National Wildlife Refuge. We walked to Pintail Lake and saw 6 Black-bellied Whistling Ducks and 2 Mississippi Kites and 1 Pied-billed Grebe. We drove the route thru the park with great results—Anhingas, Least Grebe, and more Black-bellied Whistling Ducks.
Santa Ana National Wildlife Refuge on the Rio Grande is not only a birder’s mecca, 300 species of butterflies have been identified there. That’s half the species known to occur in the United States! Its subtropical riparian forest and resaca lakes provide habitat for hundreds of migratory and resident bird species including many Central and South American species that reach the northern limit of their range in the Lower Rio Grande Valley. Two endangered cats occur in the park—the Ocelot (Leopardus pardalis) and the Jaguarundi (Herpailurus yagouaroundi).
In the Lower Rio Grande Valley, the secretive Ocelot, like the Jaguarundi, is at the northern limit of its eastern range. Time will tell how urban development including construction of the border wall will impact the distribution and survival of these and other terrestrial species there. (A modern digital image)Jaguarundi. (United States Fish and Wildlife Service image)
We saw no cats at Santa Ana, but did quite well with the birds. Our list included the species listed above plus Cattle Egret (Bubulcus ibis); Louisiana Heron, now known as Tricolored Heron (Egretta tricolor); Plain Chachalacas; Purple Gallinule; Common Gallinule (Gallinula galeata); American Coot; Killdeer; Greater Yellowlegs; the coastal Laughing Gull (Leucophaeus atricilla); and its close relative of the central flyway and continental interior, the Franklin’s Gull (Leucophaeus pipixcan). Others finds were White-winged Dove, Mourning Dove, Inca Dove, Yellow-billed Cuckoo, Golden-fronted Woodpecker, Ladder-backed Woodpecker (Dryobates scalaris), Brown-crested Flycatcher, Altamira Oriole, Great-tailed Grackle, and House Sparrow. A real standout was the colorful Green Jay (Cyanocorax luxosus), yet another tropical Central American species found north only as far as the Lower Rio Grande Valley.
During spring (April-May) and fall (August-September), Mississippi Kites migrate by the thousands through the skies of the Lower Rio Grande Valley. Both Santa Ana and nearby Bentsen-Rio Grande State Park have hosted formal hawk counts in recent years. (Vintage 35 mm image)A Black-necked Stilt at Santa Ana N.W.R.

The Altamira Oriole ranges north of Mexico only into the Lower Rio Grande Valley. (Vintage 35 mm image)
“We were unlucky not to find a campground at McAllen, so we went on to Bentsen State Park where we got a camp spot. After a sauerkraut supper, we birded till dark, then showered and wrote up the log. Very hot today.”
Bentsen-Rio Grande Valley State Park, like the Santa Ana National Wildlife Refuge, is located along the Rio Grande river and features dense subtropical riparian forest that grows in the naturally-deposited silt levees of the floodplain surrounding several lake-like oxbow resacas. Montezuma Bald Cypress (Taxodium mucronatum) is a native specialty found there but nowhere north of the Lower Rio Grande Valley. During our visit, we marveled at the epiphyte Spanish Moss (Tillandsia usneoides) adorning many of the more massive trees in the park. Willows lined much of the river shoreline.
Over time, flood control projects such as man-made dams, drainage ditches, and levees have impaired stormwater capture and aquifer recharge in the floodplain. These alterations to watershed hydrology have resulted in drier soils in many sections of the Lower Rio Grande Valley’s riparian forests. Where drier conditions persist, xeric (dry soil) scrubland plants are slowly overtaking the moisture-dependent species. As a result, the park’s woodlands are composed of trees with a variety of microclimatic requirements—Anaqua (Ehretia anacua), Cedar Elm (Ulmus crassifolia), Texas Ebony (Ebenopsis ebano), hackberry, mesquite, Mexican Ash (Fraxinus berlandieriana), retama, and tepeguaje are the principle species. The park’s subtropical Texas Wild Olive (Cordia boissieri) grows in the wild nowhere north of the Lower Rio Grande Valley.
While a majority of birders visiting Benten-Rio Grande State Park come to see the more tropical specialties of the riparian woods, searching the brushy habitat of the park’s scrubland can afford one the opportunity to see species typical of the southwestern United States and deserts of Mexico. This scrubland of the Lower Rio Grande Valley is part of the Tamaulipan Mezquital ecoregion, an area of xeric (dry soil) shrublands and deserts that extends northwest from the delta through most of south Texas and into the bordering provinces of northeastern Mexico.
Our campsite was located in prime birding habitat. We were a short walk away from one of the park’s flooded oxbow resacas and vegetation was thick along the roadsides. It was no surprise that the place abounded with birds. An evening stroll yielded Plain Chachalaca, White-winged Dove, Mourning Dove, White-fronted Dove, Golden-fronted Woodpecker, Brown-crested Flycatcher, Green Jay, Altamira Oriole, Great-tailed Grackle, and Bronzed Cowbird (Molothrus aeneus). At nightfall, we listened to the calls of an Eastern Screech Owl (Megascops asio), Common Nighthawks, and Common Pauraque (Nyctidromus albicollis), a nightjar of Central and South America that nests only as far north as the Lower Rio Grande Valley. The Common Pauraque is the tropical counterpart of the Eastern Whip-poor-will, a Neotropical migrant that nests in scattered forest locations throughout eastern North America.
The Plain Chachalaca (Ortalis vetula), a pheasant-like wildfowl of the dense riparian forest and scrubland at Bentsen-Rio Grande Valley State Park. (Vintage 35 mm image)Seldom did we see a Plain Chachalaca alone, there were always others nearby. (Vintage 35 mm image)Like the chachalacas, this White-fronted Dove was attracted to some birdseed scattered on a big log behind our campsite. This species is now known as White-tipped Dove (Leptotila verreauxi) and is at the northern tip of its range in the Lower Rio Grande Valley.
I would note that we saw no “snowbirds”—long-term vacationers from the northern states and Canada who fill the park through the cooler months of fall, winter, and spring. They were gone for the summer. But for a few other friendly folks, we had the entire campground to ourselves for the duration of our stay.
Back in late May of 1983, four members of the Lancaster County Bird Club—Russ Markert, Harold Morrrin, Steve Santner, and your editor—embarked on an energetic trip to find, observe, and photograph birds in the Lower Rio Grande Valley of Texas.

DAY THREE—May 23, 1983
For Russ, Harold, and Steve, this trip would target several bird species each individual had never observed at any prior time in their lives. Upon seeing a new bird, they could add it to their personal “life list”. They, like thousands of other “listers”, were dedicated to the goal of having a life list that included over 600 species seen in the American Birding Association (A.B.A.) area—North America north of Mexico. Harold had traveled throughout much of North America (and the world) and had an A.B.A. life list well in excess of 600 species, thus he had seen nearly all of the regularly occurring birds in the coverage area. His chance for seeing new species was limited to vagrants that might wander into North America or tropical birds that, over time, had extended their range north of Mexico into the United States. I don’t recall how many species Russ and Steve had seen, but I know each had very few opportunities for new finds east of the Rocky Mountains. For all three of these men, the Lower Rio Grande Valley presented a best bet to add multiple species to their lists. I had never been south of Cape Hatteras or west of Pennsylvania, so I had the opportunity to add dozens of species to a life list. Throughout the trip, Russ, Harold, and Steve enthusiastically helped me locate and see new species. As a result, I saw over 50 new birds to add to my list.
One of the functions of the American Birding Association was to decide which bird species an observer could add to the life list. The official A.B.A. list was revised regularly to include not only regularly occurring native species, but vagrants as well. One of the trickier determinations was the status of introduced species. Back in 1983, a birder could count a Ring-necked Pheasant seen in Pennsylvania on their A.B.A. life list because they were thought to be freely reproducing with a population sustainably established in the state. Today, they are considered an exotic release and are not countable under A.B.A. rules.
Enter the Black Francolin (Francolinus francolinus), a member of the pheasant family that back in 1983, was countable under A.B.A. rules. Native to India, the Black Francolin was introduced into southwest Louisiana in 1961 and was apparently reproducing and established. Russ had a tip that they were seen with some regularity in areas of farmland, marsh, and oil fields south of Vinton, Louisiana. It was one of this trip’s target species for his life list.
“Ready for Black Francolin. Up at 5:30 — After breakfast, we went to Gum Cove Road. No Francolins, but at the end of the blacktop road, we had 5 Purple Gallinules in the scope at one time. King Rails were plentiful. We found a dead male Painted Bunting. Later, we saw a very beautiful live one. Water everywhere. Flooded fields everywhere. The road was flooded for about 50 yards at one point. White Ibis were abundant.”
Purple Gallinules (Porphyrio martinicus) were common along Gum Cove Road. In silhouette from a distance, those that were perching atop the shrubs raised hopes that we had located the sought after Blank Francolin, but they were all Purple Gallinules. We weren’t overly disappointed. (Vintage 35 mm image)The live male Painted Bunting (Passerina cirus) seen along Gum Cove Road. (Vintage 35 mm image)
Other sightings of note along Gum Cove Road included: Northern Bobwhite, Common Nighthawk, Cattle Egret, Green Heron, American Bittern, Snowy Egret, Glossy Ibis, Black-necked Stilt (Himantopus mexicanus), Forster’s Tern, Black Tern, Yellow-billed Cuckoo, Eastern Kingbird, Purple Martin, Barn Swallow, Brown Thrasher, Loggerhead Shrike, Red-winged Blackbird, Brown-headed Cowbird, Eastern Meadowlark, Boat-tailed Grackle (Quiscalus major), and Great-tailed Grackle (Quiscalus mexicanus)—a very large and noisy blackbird I had never seen before.

The reader may be interested to know that today, the area between Vinton and the Gulf of Mexico has largely been surrendered to the forces of the hurricanes that strike the region with some regularity. Cameron Parish* is a sparsely populated buffer zone of marshes, abundant wildlife, and oil and gas wells. Its population of more than 9,000 in 1983 has plunged to less than 6,000 today. Hurricane Rita (2005) and Hurricane Ike (2008) precipitated the sharp decline. The latter hurricane had a 22-foot storm surge that flooded areas 60 miles inland of the coastline. Following these storms, the majority of severely damaged and destroyed homes were not rebuilt and residents in the most affected areas relocated. In 2020, Hurricane Laura made landfall at Cameron Parish with record-tying 150 mph winds and a storm surge that pushed flood waters inland to Lake Charles. Six weeks later, Hurricane Delta followed with 100 mph winds. For government agencies, the emergency response required by these two storms was minimized by the reduced presence of people and/or their personal property.
* A parish in Louisiana is similar to a county in other states.

Had this storm come ashore to the east at New Orleans or to the west at Houston, it would have catastrophically impacted a million people or more. (N.O.A.A./National Weather Service image)
“After a quick stop at the camp grounds, where I slipped and fell in the shower last nite, we headed south. Larry saw many birds en route.”
Russ took a bad fall on a slippery wet concrete floor and had bruises to show for it. It worried me; he was 71 years old at the time. But he was adamant about continuing on and did so with great vigor.
Just hours after a sojourn through the swampy parcels south of Vinton, we were cruising through the metropolis of Houston, Texas, then across a landscape with less cultivated cropland and more scrubland with grazing. Here and there, but primarily to the east of Houston, blankets of roadside wildflowers painted the landscape with eye-popping color. Lady Bird Johnson encouraged the plantings soon after she and Lyndon returned to Texas upon leaving life in the White House in 1969. The sight of those vivid blooms was so memorable and so beautiful. One couldn’t resist making nasty comparisons to the gobs of mowed grass and mangled trash along the highways back in Pennsylvania.
Birds along the way: Ruby-throated Hummingbird, Common Nighthawk, Black-bellied Whistling Duck, Yellow-crowned Night Heron, Great Blue, Heron, Great Egret, Black Vulture, Turkey Vulture, Red-tailed Hawk, Laughing Gull, Black Tern, Scissor-tailed Flycatcher, Cliff Swallow, Loggerhead Shrike, and Painted Bunting. I saw my first Black-bellied Whistling Ducks (Dendrocygna autumnalis) and Golden-fronted Woodpecker (Melanerpes aurifrons) near Woodsboro, Texas, and added both to my life list.
“We stopped for the nite at an A OK camp ground 7 miles south of Kingsville.”
Day Three: Vinton, Louisiana, to Kingsville, Texas, a distance of 404 miles. (United States Geological Survey base image)
Birds at the camp included two Black-bellied Whistling Ducks flying overhead, Common Nighthawk, Golden-fronted Woodpecker, Blue Grosbeak, and another “lifer”—Curve-billed Thrasher (Toxostoma curvirostre).
We also saw a Mexican Ground Squirrel (Ictidomys mexicanus), easily identified by the rows of white spots running the length of its back.
While relaxing at the campsite that evening, we watched the landscape darken and remarked how interesting it was that the glowing red sun had yet to set below the distant horizon—a land so very flat and air so hazy and humid.
We found this Common Nighthawk roosting on a tree limb near our campsite. During our first few days in Louisiana and Texas, it became increasingly evident that we were in the midst of their peak northbound spring movement. (Vintage 35 mm image)

DAY TWO—May 22, 1983
Our goal today was to continue traveling and reach western Louisiana.
“We were on our way at 6:08. Stopped for a quick lunch in the camper and drove to Vinton, Louisiana, KOA. Lots of hard rain through Tennessee, Georgia, and Alabama.
Day Two: Sweetwater, Tennessee, to Vinton, Louisiana, a distance of 786 miles. (United States Geological Survey base image)
As we crossed Mississippi and entered Louisiana, we left the rain and the Appalachians behind. Upon crossing the Mississippi River, we had arrived in the West Gulf Coastal Plain, the physiographic province that extends all the way south along the Texas coast to Mexico and includes the Lower Rio Grande Valley. West of Baton Rouge, we began seeing waders in the picturesque Bald Cypress swamps—Great Egrets, Green Herons (Butorides virescens), Little Blue Herons (Egretta caerulea), and Glossy Ibis (Plegadis falcinellus) were identified. A Pileated Woodpecker was observed as it flew above the roadside treetops.
The rains we endured earlier in the trip had left there mark in much of Louisiana and Texas. Flooding in agricultural fields was widespread and the flat landscape often appeared inundated as far as the eye could see. Along the highway near Vinton, we spotted the first two of the many southern specialties we would find on the trip, a Loggerhead Shrike (Lanius ludovicianus) and a Scissor-tailed Flycatcher (Tyrannus forficatus), both perched on utility wires and searching for a meal.
Near Vinton, Louisiana, a Loggerhead Shrike was on the lookout for either a large insect or small bird upon which it could prey. (Vintage 35 mm image)
How ’bout those Baltimore Orioles, eh? This was a banner day for them both in the trees and on the diamond. Their migration may be peaking now, but the season shows potential for much more to follow.
Here’s a quick look at just a few of the birds that have been moving northward in recent days…
Find a thicket, a garden with plenty of shrubs, or a brushy woodland and you’ll find Gray Catbirds. Many will stay in the Lower Susquehanna River Watershed to nest.Orchard Orioles favor old meadows with large shade trees. Some remain to nest.The Common Yellowthroat is one of the more than two dozen species of warblers found regularly during spring migration. It nests locally in wet thickets.The Warbling Vireo can be found singing among the branches of large streamside trees like this Green Ash.Unlike the preceding species which do the majority of their migrating by night, Blue Jays move north by daylight. Keep an eye on the sky and you just might see a flock or two go by!
For nearly a week now, a slow-moving low pressure system has not only brought heavy rain and cold temperatures to the northeastern United States, it has also stalled the northbound flights of migrating Neotropical birds. As this weather system at last drifts offshore, birds including warblers, thrushes, vireos, flycatchers, catbirds, hummingbirds, orioles, tanagers, and others should again resume their northward movements.
National Weather Service radar presently displays returns of these airborne nocturnal migrants in clear storm-free skies throughout the eastern half of the United States and Canada. As the showers and clouds depart the lower Susquehanna valley and areas to the north, the birds immediately to our south will begin to fill the void.
Gray and green halos surrounding radar stations indicate nocturnal bird migration across much of the eastern United States and Canada. Note their absence north of Maryland where the effects of the low pressure system currently located over New England are temporarily blocking these flights. (NOAA/National Weather Service radar image)
Our advice to you…plan to spend some time outdoors this weekend looking for our colorful Neotropical visitors. Their springtime songs should fill the warm air of forest and thicket. You won’t want to miss it.
The Yellow-rumped Warbler is a common migrant throughout the Lower Susquehanna River Watershed right now. Look for it and other colorful species along woodland edges, particularly where conifers are intermingled among deciduous growth.
This year’s unseasonably mild weather has hastened the northward migration of many birds. Neotropical species including warblers and Broad-winged Hawks are already pushing through the lower Susquehanna region in numbers. But it seems the spring movement may be a little bit protracted for female Red-winged Blackbirds, which are still rolling through by the hundreds despite the males being here, some of them defending nesting territories, since late February. No sense of urgency?
If you’re like us, you’re forgoing this year’s egg hunt due to the prices, and, well, because you’re a little bit too old for such a thing.
Instead, we took a closer look at some of our wildlife photographs from earlier in the week. We’ve learned from experience that we don’t always see the finer details through the viewfinder, so it often pays to give each shot a second glance on a full-size screen. Here are a few of our images that contained some hidden surprises.
We photographed these Blue-winged Teal and American Black Ducks as they were feeding in a meadow wetland…
..but upon closer inspection we located…
…a Common Green Darner patrolling for mosquitoes and other prey. The Common Green Darner is a migratory species of dragonfly. After mating, they deposit their eggs in wetland pools, ponds, and slow-moving streams.We photographed this Water Strider as it was “walking” across a pool in a small stream that meanders through a marshy meadow…
..but after zooming in a little closer we found…
…a mosquito coming to deposit its eggs had been seized as a mid-day meal. Look at how the legs of the Water Strider use the surface tension of the pool to allow it to “walk on water”, even while clutching and subduing its prey.We photographed these resident Canada Geese in a small plowed cornfield in an area managed mostly as a mix of cool-season and warm-season grassland…
..but then, following further examination, we discovered…
…a hen Ring-necked Pheasant on a nest.
THE BAD EGG
We photographed this small group of migrating Red-winged Blackbirds while it was feeding among corn stubble in a plowed field…
…but a careful search of the flock revealed…
…three female Brown-headed Cowbirds among them (the unstreaked brown birds, two to the far left and one among the “red-wings” to the right). Cowbirds practice nest parasitism as a means of putting their young up for adoption. Red-winged Blackbirds and numerous other species are the unknowing victims. The female cowbird discreetly deposits her egg(s) in the adopting party’s nest and abandons it. The cowbird egg and the hatchling that follows is cared for by the victim species, often at the expense of their own young.
Though uncommon, Rusty Blackbirds are regular spring migrants from late March into early May each year. As they make their way north through the Lower Susquehanna River Watershed, floodplain wetlands are their favored habitat. Rusty Blackbirds get their common name not only from the color of their winter plumage, but from their call note as well. It closely resembles the squeaky sound made by a rusty gate hinge.
‘Tis the first day of spring and this male American Goldfinch is beginning the molt from its drab winter garb into the spectacular feathers of its breeding plumage.
Trying to get a favorable place to nest before others arrive, the “early birds” are presently racing north through the lower Susquehanna valley. Check out these sightings from earlier today…

Time to get outside and have a look. The spectacle of spring migration passes quickly. You don’t want to miss it!
This linear grove of mature trees, many of them nearly one hundred years old, is a planting of native White Oaks (Quercus alba) and Swamp White Oaks (Quercus bicolor).
Imagine the benefit of trees like this along that section of stream you’re mowing or grazing right now. The Swamp White Oak in particular thrives in wet soils and is available now for just a couple of bucks per tree from several of the lower Susquehanna’s County Conservation District Tree Sales. These and other trees and shrubs planted along creeks and rivers to create a riparian buffer help reduce sediment and nutrient pollution. In addition, these vegetated borders protect against soil erosion, they provide shade to otherwise sun-scorched waters, and they provide essential wildlife habitat. What’s not to love?

The following native species make great companions for Swamp White Oaks in a lowland setting and are available at bargain prices from one or more of the County Conservation District Tree Sales now underway…
The Red Maple is an ideal tree for a stream buffer project. They do so well that you should limit them to 10% or less of the plants in your project so that they don’t overwhelm slower-growing species.The River Birch (Betula nigra) is a multi-trunked tree of lowlands. Large specimens with arching trunks help shade waterways and provide a source of falling insects for surface-feeding fish. Its peeling bark is a distinctive feature.The Common Winterberry with its showy red winter-time fruit is a slow-growing shrub of wet soils. Only female specimens of this deciduous holly produce berries, so you need to plant a bunch to make sure you have both genders for successful pollination.An American Robin feeding on Common Winterberry.Common Spicebush is a shrub of moist lowland soils. It is the host plant for the Spicebush Swallowtail butterfly and produces small red berries for birds and other wildlife. Plant it widely among taller trees to provide native vegetation in the understory of your forest.Common Spicebush foliage and berries in the shade beneath a canopy of tall trees.The Common Pawpaw a small shade-loving tree of the forest understory.Common Pawpaw is a colony-forming small tree which produces a fleshy fruit. It is the host plant for the caterpillars of the Zebra Swallowtail.The Buttonbush is a shrub of wet soils. It produces a round flower cluster, followed by this globular seed cluster.And don’t forget the Eastern Sycamore, the giant of the lowlands. At maturity, the white-and-tan-colored bark on massive specimens makes them a spectacular sight along stream courses and river shores. Birds ranging from owls, eagles, and herons to smaller species including the Yellow-throated Warbler rely upon them for nesting sites.Yellow-crowned Night Herons, an endangered species in Pennsylvania, nesting in an Eastern Sycamore.
So don’t mow, do something positive and plant a buffer!
Act now to order your plants because deadlines are approaching fast. For links to the County Conservation District Tree Sales in the Lower Susquehanna River Watershed, see our February 18th post.
It’s time to keep an eye on the sky when you’re out and about. Not only are mated pairs of Bald Eagles beginning their nesting cycle throughout the Lower Susquehanna River Watershed, but migrating birds are passing through the area on their way to breeding grounds farther north. This one drew the ire of pairs of Fish Crows and American Crows as it soared above the susquehannawildlife.net headquarters earlier today.
Flies? Cabbage White butterflies? Can it really be a late-February day? It certainly is. Here are a few more signs of an early spring.
Green Frogs were out and about on this balmy February day trying to latch on to one of those flying insects. Their long winter’s nap lasted just over six weeks.Approximately two hundred Common Grackles passed by susquehannawildlife.net headquarters today. This one stopped to have a look around before continuing its northbound expedition.Difficult to spot, hundreds of high-flying Canada Geese were seen in the hazy sky above the headquarters garden during the late morning. These migrants are working their way north from Chesapeake Bay and won’t be seen again in our region until fall.
Are you participating in the Great Backyard Bird Count this weekend? Have you seen a Red-breasted Nuthatch at your feeders? If not, then maybe you should see the post from earlier today so that you might order some White Pine and Eastern Hemlock trees to spruce up the habitat around your pad and improve your chances of seeing them and other interesting winter birds in coming years.
County Conservation District Tree Sales are underway throughout the Lower Susquehanna River Watershed. Now is the time to order for pickup in April.

The Eastern Hemlock, Pennsylvania’s official state tree, is an excellent choice for addition to your landscape or reforestation project. It tolerates rocky soils and its cones are an prime source of food for birds ranging from chickadees to finches.
The handsome yet underused Northern Red Oak is a sturdy long-lived native tree that is ideal for street-side, lawn, and reforestation plantings. In spring, it can be a magnet for migrating Neotropical birds when its flowers attract a wide variety of tiny insects to its upper reaches. Unlike many other oaks, this species is a relatively fast grower.
In autumn, even after the bright red foliage is gone, the berries of mature Black Gum (Nyssa sylvatica) trees attract a wide variety of birds like this Pileated Woodpecker. The Lebanon County Conservation District is offering Black Gum, also known as Black Tupelo, during their 2023 tree sale. Why not order and plant a half dozen or more?
The Perry County Conservation District is not only offering plants during this year’s sale, you can also purchase bluebird nest boxes for just $12.00 each!For less than the cost of one year of mowing, this stream corridor in Conewago Township, Dauphin County was reforested by the owner with hundreds of native trees, the majority purchased through County Conservation District Tree Sale events spanning a period of several years. By replacing bare soil and mowed areas, the riparian buffer created by these plantings has significantly reduced the nutrient and sediment loads that were polluting the small stream therein known as Brill’s Run. With determination and not a lot of money, you can do it too.But don’t forget the Eastern White Pines!
The annual arrival of hoards of American Robins to devour the fruits found on the various berry-producing shrubs and trees in the garden at susquehannawildlife.net headquarters happened to coincide with this morning’s bitter cold temperatures. Here are photos of some of those hungry robins—plus shots of the handful of other songbirds that joined them for a frosty feeding frenzy.

We don’t have a resident groundhog at susquehannawildlife.net headquarters, but the arrival of an American Robin to begin cleaning the abundance of berries from our holly trees and shrubs gives us the idea that spring is just around the corner. We could hardly be happier.
Snow days are often good days to keep an eye on the bird feeders for something unusual. Today was no exception. Two Red-breasted Nuthatches including this one were attracted to a tube full of peanuts and to the abundance of cones on the Eastern Hemlocks at susquehannawildlife.net headquarters. During autumn migration, Red-breasted Nuthatches can be somewhat common in our region but they rarely stick around, preferring instead to spend the winter in southern pine forests.
Carolina Wrens can be attracted to your garden by offering peanuts, mealworms, and suet. They are especially fond of brushy hedgerows, woodpiles, and rock walls where they forage for wintering spiders and insects. The Carolina Wren sings throughout the year, its loud “chickory-chockory-chickory” can brighten an otherwise gloomy day.
What’s under your tree this morning? It might be a Dark-eyed Junco searching for small seeds by scratching around in the leaves and detritus. Also known as the “snowbird”, the junco is a member of the Passerellidae, our native sparrow family. It winters in gardens, along forest edges, and in early successional habitat throughout the Lower Susquehanna River Watershed.
Those bluebird feeders with a one-and-a-half-inch entrance hole seem like a great way to offer supplemental foods like mealworms and raisins while excluding invasive European Starlings and other large birds from gobbling up all the expensive fare. But do they really work? Well, have a look for yourself…

There you have it. Feeders like this one are available commercially, so you don’t have an in-house wood butcher to get one. We’ve heard a rumor that Santa makes them too!
From a lookout atop an Eastern Hemlock, a Northern Mockingbird maintains a vigil over a garden full of berry-producing plants. To assure their survival during cold weather, these bold birds will vigorously defend winter food supplies on hollies, viburnums, poison-ivy, bittersweet, and other fruit-producing trees, shrubs, and vines, often swooping in to startle and flush birds and other animals that approach its stores too closely.
Our cute lovable chickadees are resident birds, remaining in the same general area throughout the year, often throughout their lives. In the Mid-Atlantic States, there are two species. The tiny Carolina Chickadee is at the northern limit of its geographic range in the Piedmont Province of southcentral Pennsylvania. The slightly larger Black-capped Chickadee is a year-round resident mostly to the north of the Lower Susquehanna River Watershed. Within the Susquehanna basin, an intergrade zone of the two species occurs in the mountains and bottomlands of the southern portion of the Ridge and Valley Province just to the north of the Pennsylvania cities of Carlisle, Harrisburg, and Lebanon. The range of the Carolina Chickadee, as well as the hybrid zone, has gradually crept north during the last fifty years—as much as twenty or thirty miles—while the range of the pure-bred Black-capped Chickadee has simultaneously withdrawn almost entirely from the lower Susquehanna, particularly in the valleys.
Every few years, presumably when their numbers are too great for the sustenance available from the wild food crop in their home range, Black-capped Chickadees invade the more southerly range of both Carolina Chickadees and the hybrids in the intergrade zone. This appears to be one of those years. Black-capped Chickadees are working their way south and showing up at feeding stations stocked with sunflower seeds, safflower seeds, and/or peanuts—sometimes in flocks numbering five to ten birds or more.
Let’s take a closer look at the two species…
In the Lower Susquehanna River Watershed from the Great Valley (Cumberland/Lebanon Valley) south into Maryland, the Carolina Chickadee is the resident species of “tit”.The Black-capped Chickadee, usually a resident of highlands to the north of the lower Susquehanna valley, is slightly larger than the Carolina Chickadee. The most conspicuous difference is the extensive amount of white in the “black-cap’s” wings, both on the edges of the flight feathers and on the set of coverts at the “shoulder”. Black-capped Chickadees often appear longer tailed and bigger headed than Carolina Chickadees and the edge of the black bib is often more ragged. The buffy wash on the flanks is usually more noticeable on the Black-capped Chickadee than on a Carolina. Hybrids from the intergrade zone, having a varying blend of characteristics, are more difficult to identify.
Not only is now a good time to carefully check the chickadees you see, but it’s an opportune time to watch for other invaders from the north, specifically the “winter fiches” including Pine Siskins, Evening Grosbeaks, Purple Finches, Red Crossbills (Loxia curvirostra), and White-winged Crossbills (Loxia leucoptera). During recent weeks, each of these species has been reported by observers at hawk-counting stations on local ridgetops, an indication that they too are experiencing inadequate food resources in their home ranges.
So, as winter approaches, you’ll want to keep an eye on those feeders—and don’t forget to keep an ear on the pines and hemlocks. The rewards could be many!
White-winged Crossbills during an invasion of the lower Susquehanna region in February 2009. Previously unnoticed in the shade, the sounds of their bills crunching the cones led to the discovery of this female (left) and male (right) among a small flock of six crossbills found feeding on Eastern Hemlock seeds at ground level.
By November, as insects become more difficult to come by, migrating Yellow-rumped Warblers are seldom found far from a supply of berries. This one was in the vicinity of the white fruits of Poison Ivy vines.
Happening right now, in the bright moonlight on a crisp autumn night, there is a massive movement of nocturnally migrating birds indicated on National Weather Service Radar from State College, Pennsylvania. Notice the dense wave crossing the lower Susquehanna River watershed from northeast to southwest. The coming morning may reveal plenty of new arrivals after daybreak. Look for robins, native sparrows, etc.
You probably know that fall is an excellent time for planting. Roots continue to grow in the warm soil even after the air becomes cool and leaves change color, setting the stage for your new trees and shrubs to sport splendid foliage and flowers in spring.
But did you know that autumn can be the best time to visit your local nursery/garden center to select the native trees and shrubs that produce berries for attracting and feeding overwintering birds and other wildlife? Here are three of our favorites. Each is looking its best from now through at least the first half of winter.
American Holly is a favorite small evergreen tree for winter beauty in the landscape. The showy red berries are produced only on female plants, so you’ll need to select at least one of each gender to grow fruit. They do best in acidic soils, responding well to a mulching of plenty of dead leaves each fall.American Robins eating American Holly berries in February.Common Winterberry is a slow-growing deciduous shrub and a member of the holly family; you’ll need both a male and a female plant to get a crop of berries. It just so happens that fall is the best time to visit the nursery for selecting a female that’s a good fruit producer. Winterberry is at its best under full sun in moist, acidic soils. These plants are very happy to receive the water from your downspouts and a mulching from the leaves in your garden.An American Robin feeds on Common Winterberry on a snowy February evening.American Beautyberry (Callicarpa americana) is a low-growing arching deciduous shrub of sunny locations in various well-drained soils. It is a plant of the southern United States that, given current temperature trends, will thrive in the Lower Susquehanna River Watershed, particularly on south-facing slopes. And yes, it does well in mass plantings on embankments.The fruits of American Beautyberry may be the most colorful of any native species.
There’s still time to get the shovel dirty, so visit your local native plant dealer this week and invest in some fruit-producing trees and shrubs. Fall is also a good time to plant pines, spruces, and hemlocks. Who knows, you might just get a good end-of-season deal.
When planted in mixed clumps, conifers like these White Pines, Norway Spruces, and Eastern Red Cedar provide excellent winter food and cover for birds and other wildlife.
Like a flycatcher, the petite Ruby-crowned Kinglet sometimes darts from its perch in pursuit of airborne insects. More frequently, you’ll see them quickly searching twigs and foliage for tiny invertebrates to snack upon. Though common in woodlands during autumn migration, only a few will remain for winter, mostly in the vicinity of pines and often in small flocks with other small birds such as chickadees and Brown Creepers. During freezing weather, kinglets probe beneath peeling bark and chunks of rotting wood for overwintering insects, including their eggs and larvae. On rare occasions, they will visit bird feeding stations to nibble on suet.
