Forty Years Ago in the Lower Rio Grande Valley: Day Three


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 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 Gallinule
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)
Painted Bunting

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.

Category 4 Hurricane Laura making landfall at Cameron Parish, Louisiana, on August 27, 2020, with wind speeds of 150 mph.  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.

Common Nighthawk
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)

Forty Years Ago in the Lower Rio Grande Valley: Day Two


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 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.

Baltimore Oriole
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.

What’s Flying Right Now

Here’s a quick look at just a few of the birds that have been moving northward in recent days…

Gray Catbird
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 Oriole
Orchard Orioles favor old meadows with large shade trees.  Some remain to nest.
Common Yellowthroat
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.
Warbling Vireo
The Warbling Vireo can be found singing among the branches of large streamside trees like this Green Ash.
Blue Jay
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!

Stalled Migration About to Resume

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.

Yellow-rumped Warbler
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?

Hidden Surprises

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.


Blue-winged Teal and American Black Ducks
We photographed these Blue-winged Teal and American Black Ducks as they were feeding in a meadow wetland…

..but upon closer inspection we located…

Common Green Darner
…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.

Water Strider
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…

Water Strider with a Mosquito
…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.

Canada Geese
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…

Ring-necked Pheasant
…a hen Ring-necked Pheasant on a nest.

THE BAD EGG

Red-winged Blackbirds
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…

Brown-headed Cowbirds and Red-winged Blackbirds
…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.

Rusty Blackbirds
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.

American Goldfinch
‘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.

Off To The Races

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…

Ring-necked Ducks

A male Red-winged Blackbird singing from a perch near a small patch of cattails.  During the spring migration, noisy flocks of males compete for a breeding territory at these sites.  Each of the victors defends his spot and awaits the arrival of a female mate while the losers move on to vie for their own breeding location farther north.

Time to get outside and have a look.  The spectacle of spring migration passes quickly.  You don’t want to miss it!

Plantings for Wet Lowlands

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?

Swamp White Oak

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…

Red Maple
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.
River Birch
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.
Common Winterberry
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.

Common Spicebush
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.

Common Pawpaw
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.
Buttonbush
The Buttonbush is a shrub of wet soils.  It produces a round flower cluster, followed by this globular seed cluster.
Eastern Sycamore
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.

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.

Soaring Bald Eagle
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.

These Geese are Outta Here!

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 Frog
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.
Common Grackle
Approximately two hundred Common Grackles passed by susquehannawildlife.net headquarters today.  This one stopped to have a look around before continuing its northbound expedition.
Migrating Canada Geese
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.

Female Red-breasted Nuthatch
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.

Riparian Buffer at 15 Years
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.
Maples, Pin Oaks, Eastern White Pines, and other trees in the Brill's Run riparian buffer.
But don’t forget the Eastern White Pines!

Berries and More on a Bitter Cold Morning

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.

Red-breasted Nuthatch
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 Wren
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.

Dark-eyed Junco
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.

Do Those Bluebird Feeders Really Work?

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!

Northern Mockingbird
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.

Black-capped Chickadee Invasion

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, the Carolina Chickadee is the resident species from the Great Valley (Cumberland/Lebanon Valley) south into Maryland.

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!

Yellow-rumped Warbler
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.

Nocturnal Migrants in Moonlight

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.

Select Your Berry-producing Plants Now

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
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.

Common Winterberry
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.

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.

White Pines, Norway Spruces, and Eastern Red Cedar
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.

Ruby-crowned Kinglet
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.

Hermit Thrushes
Earlier today, these migrants were found feeding on berries along the edge of a forest clearing in northern Lebanon County, Pennsylvania.  Can you find the three Hermit Thrushes among the early successional growth seen here?   For extra credit, identify the three species of berry-producing pioneer plants that are shown.  For additional credit, which one of these plants is a non-native invasive species?   Click the image to see how you did.

Eastern Phoebe
This migrating Eastern Phoebe is on the lookout for flying insects, a scarce find on cold autumn mornings.  Eastern Phoebes are the hardiest of our flycatchers and are among the last of our insectivorous birds to head south in the fall.  They’ll return in mid-March feeding on stoneflies and other early-emerging insects along streams and rivers.
