American Oystercatcher - Ross Feldner

There’s no mistaking this dramatically colored shorebird with an obvious name that is indeed an expert at dining on shellfish of all kinds. It relies on two methods of opening shells. If it finds a partly opened mussel for instance, the oystercatcher will jab its bill into the opening and snag the meal. The second method requires way more work. It simply hammers repeatedly on the shell to break it open. The American Oystercatcher is exclusively coastal, favoring beaches that offer shellfish and other invertebrates.

Like so many other birds, American Oystercatchers were nearly hunted to extinction in the 19th century for their plumage and eggs. The populations recovered after the Migratory Bird Treaty Act of 1918 was passed although some states still consider a species of concern.

This uniquely patterned bird still faces major threats from coastal development, human disturbance and climate change. It is particularly susceptible to the danger of plastic trash as it will often mistake it for food, with fatal results.

The American Oystercatcher is one of the few bird species that specializes in feeding on saltwater mollusks.

Once known as the "sea pie," it was renamed in 1731 when naturalist Mark Catesby observed the bird eating oysters.

It is typically a short-distance migrant.

Oystercatchers signal each using yelps, whistles and piping noises.

A group of oystercatchers is known as a "parcel" or "stew."

Its nest is simply a scrape in the sand, without lining.​
