Why birders from across America keep showing up to this quiet corner of Delaware Bay

It’s one of the East Coast’s best bird stops

Bombay Hook National Wildlife Refuge sits on eight miles of Delaware Bay coastline in Kent County, and about four-fifths of it is tidal salt marsh.

The rest spreads across freshwater pools, forests, swamps and fields, all packed into 16,251 acres.

Nearly 350 bird species have been recorded here, and the site holds both Ramsar Wetland of International Importance status and a Globally Important Bird Area designation. Around 100,000 people visit each year.

Most of them come back.

The name started as Dutch for “little-tree point”

Native Americans called this land Canaresse, meaning “at the thickets.”

Dutch settlers renamed it Boompjes Hoeck, or “little-tree point,” and over time that became Bombay Hook.

On March 16, 1937, the federal government established the refuge as one link in a chain running along the Atlantic Flyway from Canada to the Gulf of Mexico. Federal duck stamp funds paid for the land.

A year later, the Civilian Conservation Corps started building the pools, dikes, observation tower and headquarters you still use today.

A 12-mile loop past four freshwater pools

The wildlife drive is how most people see Bombay Hook.

It’s a 12-mile loop on flat dirt and gravel roads that winds past freshwater pools, salt marsh, woodlands and open fields. You can drive it, bike it or walk parts of it.

The route passes all four major pools: Raymond, Shearness, Finis and Bear Swamp. Pull-off areas line the road so you can stop, watch and shoot photos without holding up traffic.

Bring binoculars and take your time.

Watch 10,000 geese lift off at sunrise from Raymond Pool

Raymond Pool is the first freshwater pool you hit along the wildlife drive.

A quarter-mile trail leads to a 30-foot observation tower that looks out over the water and the surrounding upland fields. During spring migration, the pool fills with ducks, snow geese and Canada geese.

If you get there at sunrise, you can watch massive flocks of waterfowl lift off the water all at once. The sound alone is worth the early alarm.

Shearness Pool can hold over 100,000 snow geese

Shearness is the largest of the four freshwater pools, and it’s the place on the refuge where you’re most likely to spot a bald eagle. They nest in the woods behind the pool.

But the real show comes in late fall and winter, when snow geese pile in by the tens of thousands, sometimes topping 100,000 birds. At dusk, wave after wave returns from nearby farm fields to roost on the water.

Another quarter-mile trail takes you to a second 30-foot tower with wide views.

A floating deck and spotting scope at Bear Swamp

Bear Swamp Pool came along in 1961, the newest of the four.

A quarter-mile loop through hardwood forest brings you to a 30-foot observation tower and a floating observation deck with a spotting scope already set up. The trail is wheelchair accessible.

In summer, the pool’s islands fill with great blue herons, great egrets, snowy egrets and black-crowned night herons. Keep your eyes on the tree line, too.

Foxes show up there, and turtles bask along the banks.

Walk right over the salt marsh on the boardwalk

The Boardwalk Trail runs a quarter-mile loop straight out over the tidal salt marsh. Below you, cordgrass meadows give way to mud flats, tidal pools and narrow creeks that twist through the reeds.

This marsh works as a nursery for marine life and a feeding ground for wading birds and raptors.

You’re standing over one of the most ecologically important habitats in Delaware, and at high tide the water moves right under your feet.

Morning light on the pools, afternoon light on the marsh

Photographers come to Bombay Hook for the light. Morning sun hits the freshwater pools, and the tidal salt marsh to the east catches afternoon glow.

Sunrise over the marsh reeds is the shot most people want.

But the range of subjects keeps you busy all day: raptors in flight, herons fishing the shallows, fox kits playing near their dens, snow geese lifting off by the thousands.

The slow pace of the wildlife drive lets you shoot from your car without spooking anything.

Eagle chicks leave the nest by June

Spring migration peaks in March, when ducks, snow geese and Canada geese crowd the pools. Bald eagle eggs hatch in April, and by June the young eagles leave the nest.

May is when shorebird numbers hit their highest and horseshoe crabs start spawning along the Delaware Bay shore. Warbler migration also peaks in May, with spring wildflowers in full bloom across the refuge.

By summer, herons, egrets and black-necked stilts settle in to nest on the pools.

Bare branches in winter make every bird easy to spot

Fall shorebird migration starts in late July and builds through September. By October and November, ducks and geese pour in, with total waterfowl sometimes reaching 150,000.

Winter is when you’ll see the most raptors: bald eagles, red-tailed hawks and northern harriers perched on bare branches with nothing to hide them. Tundra swans arrive in December and stay through February.

The leafless landscape strips away every hiding spot, and that makes winter the easiest season to photograph birds.

A 1753 brick farmhouse and a U.S. quarter

The Allee House sits on refuge grounds, built around 1753 by Abraham Allee, the son of a French Huguenot refugee.

It’s one of the finest early Delaware brick farmhouses still standing, with original Flemish bond brickwork.

It landed on the National Register of Historic Places in 1971 but is currently closed for structural repairs from water damage.

In 2015, Bombay Hook appeared on the America the Beautiful quarter, the 29th coin in the series, with a great blue heron and great egret in the salt marsh.

The longest trail puts you under a forest canopy

At 2.7 miles, the Forest Discovery Tree Trail is the longest path on the refuge and feels different from everything else here.

Instead of open marsh and water, you walk under a woodland canopy through old-growth and new-growth forest. Numbered trees along the route come with an identification key, so you learn as you go.

Woodpeckers, songbirds and white-tailed deer move through the woods. If you want a longer, quieter walk away from the driving loop, this is it.

Explore Bombay Hook National Wildlife Refuge in Delaware

You can visit Bombay Hook year-round at 2591 Whitehall Neck Road in Smyrna, Del. The refuge opens half an hour before sunrise and closes half an hour after sunset.

The visitor center runs from 9 a.m. to 4 p.m. daily, though hours depend on weather and volunteers, and it closes on federal holidays. Loaner binoculars and trail guides are free at the front desk.

The refuge closes three days a year for managed deer hunts, so check the official website before you go. One warning: mosquitoes and biting flies hit hard from June through September, so pack long sleeves and repellent.
