Have you purchased your 2023-2024 Federal Duck Stamp? Nearly every penny of the 25 dollars you spend for a duck stamp goes toward habitat acquisition and improvements for waterfowl and the hundreds of other animal species that use wetlands for breeding, feeding, and as migration stopover points. Duck stamps aren’t just for hunters, purchasers get free admission to National Wildlife Refuges all over the United States. So do something good for conservation—stop by your local post office and get your Federal Duck Stamp.
Your Federal Duck Stamp is your admission ticket for entry into many of the country’s National Wildlife Refuges including Bombay Hook National Wildlife Refuge on Delaware Bay near Smyrna, Delaware.
Still not convinced that a Federal Duck Stamp is worth the money? Well then, follow along as we take a photo tour of Bombay Hook National Wildlife Refuge. Numbers of southbound shorebirds are on the rise in the refuge’s saltwater marshes and freshwater pools, so we timed a visit earlier this week to coincide with a late-morning high tide.
This pair of Northern Bobwhite, a species now extirpated from the Lower Susquehanna River Watershed and the rest of Pennsylvania, escorted us into the refuge. At Bombay Hook, they don’t waste your money mowing grass. Instead, a mosaic of warm-season grasses and early successional growth creates ideal habitat for Northern Bobwhite and other wildlife.Twice each day, high tide inundates mudflats in the saltwater tidal marshes at Bombay Hook prompting shorebirds to move into the four man-made freshwater pools. Birds there can often be observed at close range. The auto tour route through the refuge primarily follows a path atop the dikes that create these freshwater pools. Morning light is best when viewing birds on the freshwater side of the road, late-afternoon light is best for observing birds on the tidal saltwater side.A Great Blue Heron at high tide on the edge of a tidal creek that borders Bombay Hook’s tour route at Raymond Pool.Semipalmated Sandpipers stream into Raymond Pool to escape the rising tide in the salt marsh.More Semipalmated Sandpipers and a single Short-billed Dowitcher (Limnodromus griseus) arrive at Raymond Pool.Two more Short-billed Dowitchers on the way in.Recent rains have flooded some of the mudflats in Bombay Hook’s freshwater pools. During our visit, birds were often clustered in areas where bare ground was exposed or where water was shallow enough to feed. Here, Short-billed Dowitchers in the foreground wade in deeper water to probe the bottom while Semipalmated Sandpipers arrive to feed along the pool’s edge. Mallards, American Avocets, and egrets are gathered on the shore.More Short-billed Dowitchers arriving to feed in Raymond Pool.Hundreds of Semipalmated Sandpipers gathered in shallow water where mudflats are usually exposed during mid-summer in Raymond Pool.Hundreds of Semipalmated Sandpipers, several Short-billed Dowitchers, and some Forster’s Terns (Sterna forsteri) crowd onto a mud bar at Bear Swamp Pool.A zoomed-in view of the previous image showing a tightly packed crowd of Semipalmated Sandpipers, Forster’s Terns, and a Short-billed Dowitcher (upper left).Short-billed Dowitchers wading to feed in the unusually high waters of Raymond Pool.Short-billed Dowitchers, American Avocets, and a Snowy Egret in Raymond Pool.

This sandpiper, still in breeding plumage, is a little bit early. Many migrating Dunlin linger at Bombay Hook into October and even November.This Least Sandpiper found a nice little feeding area all to itself at Bear Swamp Pool.Lesser Yellowlegs at Bear Swamp Pool.Lesser Yellowlegs at Bear Swamp PoolA Greater Yellowlegs at Bear Swamp Pool.A Caspian Tern patrolling Raymond Pool.The chattering notes of the Marsh Wren’s (Cistothorus palustris) song can be heard along the tour road wherever it borders tidal waters.This dome-shaped Marsh Wren nest is supported by the stems of Saltwater Cordgrass (Sporobolus alterniflorus), a plant also known as Smooth Cordgrass. High tide licks at the roots of the cordgrass supporting the temporary domicile.By far the most common dragonfly at Bombay Hook is the Seaside Dragonlet (Erythrodiplax berenice). It is our only dragonfly able to breed in saltwater. Seaside Dragonlets are in constant view along the impoundment dikes in the refuge.Red-winged Blackbirds are still nesting at Bombay Hook, probably tending a second brood.Look up!

Unlike gregarious Tundra and Mute Swans, pairs of Trumpeter Swans prefer to nest alone, one pair to a pond, lake, or sluggish stretch of river. The range of these enormous birds was restricted to western North America and their numbers were believed to be as low as 70 birds during the early twentieth century. An isolated population consisting of several thousand birds was discovered in a remote area of Alaska during the 1930s allowing conservation practices to protect and restore their numbers. Trumpeter Swans are slowly repopulating scattered east coast locations following recent re-introduction into suitable habitats in the Great Lakes region.A Great Egret prowling Shearness Pool.A Snowy Egret in Bear Swamp Pool.Wood Ducks in Bear Swamp Pool.A Bombay Hook N.W.R. specialty, a Black-necked Stilt and young at Bear Swamp Pool.
As the tide recedes, shorebirds leave the freshwater pools to begin feeding on the vast mudflats exposed within the saltwater marshes. Most birds are far from view, but that won’t stop a dedicated observer from finding other spectacular creatures on the bay side of the tour route road.
Bombay Hook National Wildlife Refuge protects a vast parcel of tidal salt marsh and an extensive network of tidal creeks. These areas are not only essential wildlife habitat, but are critical components for maintaining water quality in Delaware Bay and the Atlantic.The shells of expired Atlantic Horseshoe Crabs were formerly widespread and common among the naturally occurring flotsam along the high tide line on Delaware Bay. We found just this one during our visit to Bombay Hook. Man has certainly decimated populations of this ancient crustacean during recent decades.As the tide goes out, it’s a good time for a quick walk into the salt marsh on the boardwalk trail opposite Raymond Pool.Among the Saltmarsh Cordgrass along the trail and on the banks of the tidal creek there, a visitor will find thousands and thousands of Atlantic Marsh Fiddler Crabs (Minuca pugnax).Atlantic Marsh Fiddler Crabs and their extensive system of burrows help prevent the compaction of tidal soils and thus help maintain ideal conditions for the pure stands of Saltwater Cordgrass that trap sediments and sequester nutrients in coastal wetlands.A male Atlantic Marsh Fiddler Crab peers from its den.Herons and egrets including this Great Egret are quite fond of fiddler crabs. As the tide goes out, many will venture away from the freshwater pools into the salt marshes to find them.A Green Heron seen just before descending into the cordgrass to find fiddler crabs for dinner.A juvenile Clapper Rail (Rallus crepitans crepitans) emerges from the cover of the cordgrass along a tidal creek to search for a meal.Glossy Ibis leave their high-tide hiding place in Shearness Pool to head out into the tidal marshes for the afternoon.Great Black-backed Gulls, Herring Gulls, and possibly other species feed on the mudflats exposed by low tide in the marshes opposite Shearness Pool.An Osprey patrols the vast tidal areas opposite Shearness Pool.
No visit to Bombay Hook is complete without at least a quick loop through the upland habitats at the far end of the tour route.
Indigo Buntings nest in areas of successional growth and yes, that is a Spotted Lanternfly on the grape vine at the far right side of the image.Blue Grosbeaks (Passerina caerulea) are common nesting birds at Bombay Hook. This one was in shrubby growth along the dike at the north end of Shearness Pool.These two native vines are widespread at Bombay Hook and are an excellent source of food for birds. The orange flowers of the Trumpet Vine are a hummingbird favorite and the Poison Ivy provides berries for numerous species of wintering birds.The Pileated Woodpecker is one of the numerous birds that supplements its diet with Poison Ivy berries. The tree this individual is visiting is an American Sweetgum (Liquidambar styraciflua), a species native to the Atlantic Coastal Plain in Delaware. The seed balls are a favorite winter food of goldfinches and siskins.Finis Pool has no frontage on the tidal marsh but is still worth a visit. It lies along a spur road on the tour route and is located within a deciduous coastal plain forest. Check the waters there for basking turtles like this giant Northern Red-bellied Cooter (Pseudemys rubiventris) and much smaller Painted Turtle.The White-tailed Deity is common along the road to Finis Pool.Fowler’s Toads (Anaxyrus fowleri) breed in the vernal ponds found in the vicinity of Finis Pool and elsewhere throughout the refuge.The National Wildlife Refuge System not only protects animal species, it sustains rare and unusual plants as well. This beauty is a Turk’s Cap Lily (Lilium superbum), a native wildflower of wet woods and swamps.Just as quail led us into the refuge this morning, this Wild Turkey did us the courtesy of leading us to the way out in the afternoon.
We hope you’ve been convinced to visit Bombay Hook National Wildlife Refuge sometime soon. And we hope too that you’ll help fund additional conservation acquisitions and improvements by visiting your local post office and buying a Federal Duck Stamp.
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 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)
