We had a wonderful couple days searching the extensive
marshes along the Atlantic Ocean and Delaware Bayshore for raptors of all kinds
on this exciting School of Birding Workshop. These marshes play host to a large diversity
and number of raptors and other birds, as evidenced by the checklist below.
Bald Eagles and Northern Harriers were especially numerous, allowing for the
study of various plumages relating to age and sex. We encountered numerous
adult and juvenile Bald Eagles, with several two and three-year old birds seen,
as well. Northern Harriers were overwhelmingly in the juvenile category, but several
adult females were noted, along with a single “Gray Ghost” adult male. Interesting
behaviors were enjoyed both days, including a Merlin unsuccessfully chasing a
Yellow-rumped Warbler and harassing a Cooper’s Hawk, a Red-tailed Hawk mantling
carrion to discourage Turkey Vultures, a Short-eared Owl dive-bombing a
Rough-legged Hawk, and a Rough-legged Hawk forcing a Northern Harrier to drop
its prey. The adult Peregrine Falcon that passed by in the glowing sunset at
Jake’s Landing was carrying some sort of prey. Even the gulls were very
predatory, as we watched a Great Black-backed Gull catch and dispatch a
Bufflehead along the beach. It was a fun weekend with many highlights,
including an adult Golden Eagle. Although focused on raptors, a full
