(This is Part 2 of the post “2017 Birding Vacation!”. If you’d like to read Part 1 of our trip, click this link)
We had a blast birding in Maryland at Pickering Creek Audubon Center and checking out the National Aquarium, but the fun wasn’t over yet. The following day Dave and I drove into Delaware to go birding at Bombay Hook National Wildlife Refuge.
Bombay Hook is a 16,251 acre wildlife refuge located on the coast of Delaware near Delaware Bay. The refuge is mainly tidal salt marshes, but also features freshwater impoundments as well as upland habitats. Bombay Hook is a sanctuary and breeding ground for migratory birds as well as a variety of other animals. Spring at the refuge features the large concentration of shorebirds as well as warblers.
We arrived at the visitor center in the morning to a flurry of bird activity. There was a Purple Martin colony and the feeders were busy with House Finches, American Goldfinches, and sparrows. One particular male House Finch was more of an orange shade than red. Plumage (feathers) can vary in color based on diet, so if a finch is lacking certain nutrients it may be orange or yellowish. There was a short loop behind the center where we saw Indigo Buntings, Blue Grosbeaks, Yellow Warblers, woodpeckers, and a few Northern Mockingbirds. We even saw a cute immature Mockingbird.

Like Edwin B. Forsythe NWR, there is a wildlife drive that winds through the marsh and upland habitats. The drive begins at the Raymond Pool, which has a short Boardwalk Trail and an observation tower. Out in the pool there was a huge flock of Semipalmated Sandpipers, Short-billed Dowitchers, a Semipalmated Plover, Dunlins, a Solitary Sandpiper, and the bird I’ve been waiting for: the American Avocet. When I was planning our vacation and saw that we could see Avocets at Bombay Hook I knew we had to go. These elegant birds have long legs, rusty-colored necks, and a long upturned bill. They were beautiful to see in person.

On the other side of the pool we found some Snow Geese, Laughing Gulls, terns, Great Blue Herons, Great Egrets, Red-winged Blackbirds, Double-crested Cormorants, and Common Yellowthroats. This trip was the first time that I’ve seen Dunlins in their breeding plumage. When they visit New Jersey in the winter they lack their large black belly spot, so it was cool to see them in breeding mode. A juvenile Bald Eagle appeared and picked up a dead bird that was nearby. We knew it was a juvenile because it was all brown and lacked the white head/tail feathers. It was one of 4 Bald Eagles we saw during the trip.
The Boardwalk Trail looped around a small section of the marsh, and there were Marsh Wrens everywhere. We see Marsh Wrens at Boundary Creek in the summer, but this trail was cool because you were on eye level with them. Marsh Wrens buzz around the cattails and reeds with their tails cocked up while making an elaborate, gurgling rattle. We weren’t able to get any good pictures since they were usually deep in the reeds, but we did get one of their nests. On the boardwalk we also saw Eastern Kingbirds, a female Northern Harrier, Tree Swallows, and Barn Swallows.

The next part of the loop was the Shearness Pool, which also had a short trail and an observation tower. This is were we saw our first Black-necked Stilts. These black-and-white beauties have long, thin red legs. Stilts have the second-longest legs in proportion to their bodies of any bird (second to flamingos of course). Nearby waded an unusual looking bird. It look nervous, constantly bobbing its head while it walked. It was deep in the water though, and you couldn’t see it’s legs. It’s neck was red, had a clean white belly, a thin bill, grayish-brown upperparts, and a very distinctive black eye patch. After much deliberation, we determined it was a female Wilson’s Phalarope. They are one of the few birds were the “gender roles” are switched: the females are more colorful than the males and defend the males who are busy raising the young. When I enter our finding into ebird, it came up as “rare” (even though our list from Bombay said they were “occassional”. I’ll keep you updated if our Phalarope is confirmed, but it was cool to find a rare bird on vacation. (Sorry the Phalarope photo is real blurry, it was use for proof, but maybe you might be able to confirm it for me)

Bear Swamp Pool featured a large flock of Black-bellied Plovers in the stunning breeding plumage. We did see one at Forsythe recently (while looking for the American Golden-Plover), but it wasn’t in breeding plumage. There were at least 60 relaxing on the mudflats. An Osprey appeared and was hovering over the water for a bit. We were watching it dive for fish, and a few more Ospreys appeared, until there were at least 5 fishing over the pool. Then a more unexpected visitor arrived: a raccoon. The raccoon was on the other side of the pool and swam over to our side. It was amusing to see a raccoon swimming in the salt marsh in the middle of the day. We drove up closer to where it stepped on land and it popped it’s head out of the bushes to look at us before hiding!

The last area was the Finis Pool. One the way we heard an interesting call from the woods; 3 clear notes ascending. We didn’t figure out who it was at the time, but I recorded it and learned yesterday it was a Northern Bobwhite singing his “poor-bob-WHITE!” song. We also stumbled upon some Great Egrets resting in a tree. It took a few minutes to realize they weren’t alone: there was a Little Blue Heron right next to them! On the way out we actually found a Bobwhite before it quickly ran back into the bushes.

We saw a whopping 55 species on our Bombay Hook Trip with 4 life birds (avocet, stilts, phalarope, and bobwhite). To see the full eBird checklist you can click this link. Combined with our Maryland trip we saw 6 life birds (the 2 Maryland ones were the Yellow-breasted Chat and White-eyed Vireo). We had an amazing time on our 2017 Maryland and Delaware birding adventure!
