It’s surprising how many millions of people travel the busy coastal routes of Delaware each year to leave the traffic congestion and hectic life of the northeast corridor behind to visit congested hectic shore towns like Rehobeth Beach, Bethany Beach, and Ocean City, Maryland. They call it a vacation, or a holiday, or a weekend, and it’s exhausting. What’s amazing is how many of them drive right by a breathtaking national treasure located along Delaware Bay just east of the city of Dover—and never know it. A short detour on your route will take you there. It’s Bombay Hook National Wildlife Refuge, a quiet but spectacular place that draws few crowds of tourists, but lots of birds and other wildlife.
Bombay Hook National Wildlife Refuge is located just off Route 9, a lightly-traveled coastal road east of Dover, Delaware. Note the Big Bluestem and other warm season grasses in the background. Bombay Hook, like other refuges in the system, is managed for the benefit of the wildlife that relies upon it to survive. Within recent years, most of the mowed grass and tilled ground that once occurred here has been replaced by prairie grasses or successional growth, much to the delight of Northern Bobwhite (Colinus virginianus) and other species.
Let’s join Uncle Tyler Dyer and have a look around Bombay Hook. He’s got his duck stamp and he’s ready to go.
Uncle Ty’s current United States Fish and Wildlife Service Duck Stamp displayed on his dashboard is free admission to the tour road at Bombay Hook and other National Wildlife Refuges.The refuge at Bombay Hook includes woodlands, grasslands, and man-made freshwater pools, but it is predominately a protectorate of thousands of acres of tidal salt marsh bordering and purifying the waters of Delaware Bay. These marshes are renowned wintering areas for an Atlantic population of Snow Goose known as the “Greater Snow Goose” (Anser caerulescens atlanticus). Witnessing thousands of these birds rising over the marsh and glowing in the amber light of a setting sun is an unforgettable experience.Trails at various stops along the auto tour route lead to observation towers and other features. This boardwalk meanders into the salt marsh grasses and includes a viewing area alongside a tidal creek. Our visit coincided with a very high tide induced by east winds and a new moon.During high tide, an Eastern Cottontail (Sylvilagus floridanus) seeks higher ground near the boardwalk and the wooded edge of the salt marsh.As the tide rises, fast-flying shorebirds scramble from flooded mudflats in the salt marsh on the east side of the tour road.When high tide arrives in the salt marshes, shorebirds and waterfowl often concentrate in the man-made freshwater pools on the west side of the tour road. Glaring afternoon sun is not the best for viewing birds located west of the road. For ideal light conditions, time your visit for a day when high tide occurs in the morning and recedes to low tide in the afternoon.A view looking west into Shearness Pool, largest of the freshwater impoundments at Bombay Hook.Bombay Hook has many secretive birds hiding in its wetlands, but they can often be located by the patient observer. Here, two Pied-billed Grebes feed in an opening among the vegetation in a freshwater pool.One of Bombay Hook’s resident Bald Eagles patrols the wetlands.American Avocets (Recurvirostra americana) gather by the hundreds at Bombay Hook during the fall. A passing eagle will stir them into flight.An American Avocet, a delicate wader with a peculiar upturned bill.As soon as the tide begins receding, shorebirds and waterfowl like these Green-winged Teal begin dispersing into the salt marshes to feed on the exposed mudflats.The woodlands and forested areas of the refuge host resident songbirds and can be attractive to migrating species like this Yellow-rumped Warbler.For much of its course, the tour road at Bombay Hook is located atop the dike that creates the man-made freshwater pools on the western edge of the tidal salt marsh. If you drive slowly and make frequent stops to look and listen, you’ll notice an abundance of birds and other wildlife living along this border between two habitats. Here, a Swamp Sparrow has a look around.Savannah Sparrows are common along the tour road where native grasses grow wild.Bombay Hook is renowned for its rarities. One of the attractions during the late summer and autumn of 2021 was a group of Roseate Spoonbills (Platalea ajaja), vagrants from the southern states, seen here with Great Egrets and Snowy Egrets (Egretta thula).Roseate Spoonbills and Great Egrets at Bombay Hook.
Remember to go the Post Office and get your duck stamp. You’ll be supporting habitat acquisition and improvements for the wildlife we cherish. And if you get the chance, visit a National Wildlife Refuge. November can be a great time to go, it’s bug-free! Just take along your warmest clothing and plan to spend the day. You won’t regret it.
So you aren’t particularly interested in a stroll through the Pennsylvania woods during the gasoline and gunpowder gang’s second-biggest holiday of the year—the annual sacrifice-of-the-White-tailed-Deity ritual. I get it. Two weeks and nothing to do. Well, why not try a hike through the city instead? I’m not kidding. You might be surprised at what you see. Here are some photographs taken today during several strolls in Harrisburg, Pennsylvania.
First stop was City Island in the Susquehanna River—accessible from downtown Harrisburg or the river’s west shore by way of the Market Street Bridge.
From the middle of the Susquehanna River, City Island offers a spectacular view of the downtown Harrisburg skyline. In summer, it’s the capital city’s playground. During the colder months, it’s a great place to take a quiet walk and find unusual birds.This Bald Eagle was in mature trees along the river shoreline near the Harrisburg Senator’s baseball stadium.Ring-billed Gulls gather on the “cement beach” at the north end of City Island.One of a dozen or so Herring Gulls seen from the island’s north end. This particular bird is a juvenile.A Ring-billed Gull and some petite Bonaparte’s Gulls. Really good birders will tell you to always check through flocks of these smaller gulls carefully. It turns out they’re onto something. Look closely at the gull to the right.A bright red bill and more of a crescent shape to the black spot behind the eye, that’s an adult Black-headed Gull (Chroicocephalus ridibundus) in winter plumage, a rare bird on the Susquehanna. Black-headed Gulls have colonized North America from Europe, breeding in Iceland, southernmost Greenland, and rarely Newfoundland.
Okay, City Island was worth the effort. Next stop is Wildwood Park, located along Industrial Road just north of the Pennsylvania Farm Show complex and the Harrisburg Area Community College (HACC) campus. There are six miles of trails surrounding mile-long Wildwood Lake within this marvelous Dauphin County Parks Department property.
A flock of Killdeer at the south end of Wildwood Lake. From November through February, a walk along the south and west sides of the impoundment can be a photographer’s dream. The light is suitable in the morning, then just keeps getting better as the day wears on.Is this probable Carolina/Black-capped Chickadee hybrid a resident at Wildwood or just a visitor from a few miles to the north? Currently, pure Black-capped Chickadees (Poecile atricapillus) nest in the mountains well to the north of Harrisburg, and pure Carolina Chickadees nest south of the city. Harrisburg possibly remains within the intergrade/hybrid zone, an area where the ranges of the two species overlap, but probably not for long. During recent decades, this zone has been creeping north, at times by as much as a half mile or more each year. So if the capital city isn’t Carolina Chickadee territory yet, it soon will be.Another chickadee likely to be a hybrid, this one with some white in the greater wing coverts like a Black-capped, but with a call even more rapid than that of the typical Carolina, the species known for uttering the faster “chick-a-dee-dee-dee”. It sounded wired, like it had visited a Starbucks all morning.In the lower Susquehanna valley, Carolina Chickadees have already replaced hybrids and pure Black-capped Chickadees as nesting birds in the Piedmont hills south of Harrisburg and the Great Valley. This Carolina Chickadee was photographed recently in the Furnace Hills at Middle Creek Wildlife Management Area in northern Lancaster County. The transition there was probably complete by the end of the twentieth century. Note the characteristic overall grayish appearance of the wings and the neat lower border of the black bib on this bird, For comparison, a bird presumed to be a pure Black-capped Chickadee photographed earlier this month in Lebanon County, Pennsylvania. This fall, “Black-caps”, like many other northern perching birds, are moving south to invade the lower elevations and milder climes of the Piedmont and Atlantic Coastal Plain Provinces. Note the extensive areas of white in the wings, the long tail, the buffy flanks, and the jagged edge of the black bib.Along Wildwood Lake’s west shore, an adult male Sharp-shinned Hawk was soon attracted to the commotion created by bantering chickadees and other songbirds.Yellow during the first year, the eyes of the Sharp-shinned Hawk get redder as the bird ages.Also along the west border of Wildwood Lake, temperatures were warm enough to inspire Painted Turtles (Chrysemys picta) to seek a sun bath atop logs in the flooded portions of the abandoned Pennsylvania Canal.
And now, without further ado, it’s time for the waterfowl of Wildwood Lake—in order of their occurrence.

Isn’t that great light by late afternoon?
See, you don’t have to cloak yourself in bright orange ceremonial garments just to go for a hike. Go put on your walking shoes and a warm coat, grab your binoculars and/or camera, and have a look at wildlife in a city near you. You never know what you might find.
