American Oyster-catcher

The American Oyster-catcher, a really cool bird not often seen.

Haemateopus palliatus.

According to Birds of America (Pearson & Burroughs), the Oyster-catcher is essentially a maritime bird.

They are found (except by accident) only on the ocean fronts, where they get the principle part of their diet: oysters, clams, mussels, and various shell fish. They open the shells with the handy oyster knife which they carry (the bright-red bill). They will also feed on marine worms and insects. Locally in many places, they are called “Sea-Crows” by fishermen, which may be an apt title, although the call is melodious and flute-like rather than like the raucous call of the true Crow.

The birds have stout legs and strong feet from which the hind toe is missing. The plumage is black on the head and upper part, white underneath with a brownish back.

We photographed this bird in October. We watched him/her walk with a slow dignified stride before we snapped the photo. They can run with considerable speed and usually only fly short distances if disturbed. This one is a juvenile, as determined by beak color (not fully red yet).

Females usually lay only 2 to 3 cream-colored eggs blotched with brown, in a slight depression in the sand. Sometimes the nest will be in a pile of shell castings on a small area of sand, or on shell bars with bunches of seaweed which is not covered at high tide. The eggs are very hard to find as they blend right in with their surroundings. They typically nest from April to June with the female doing most of the incubation at night or on cool cloudy days. The nest will typically be left uncovered during the day to allow the sun and warm sand to provide incubation.

The similar Black Oyster-catcher is usually only found from Alaska and the Aleutians to central and sometimes southern California, whereas the American Oyster-catcher resides on the southern and eastern coasts of the U.S. casual to New Brunswick.
