Most shorebirds are not known for their vibrant colors or contrasting plumage. But the American Oystercatcher is an exception. It is exceptional in other ways as well, including its feeding and migration behavior.
Let’s begin with appearance. The face is clownish, with a bright yellow eye surrounded by a bright red eye-ring. Add a stunning, long orange bill to a black head and neck, and you have a very unique-looking bird. Particularly when you consider that it’s a shorebird. On top of the garish colors, this bird has very thick, stout pinkish legs. Legs that more resemble the legs of a gull rather than the thin, fast-moving legs of most shorebirds. Most shorebirds have a breeding plumage and a non-breeding plumage. The Oystercatcher looks the same in December as it does in April. Juvenile birds are similar in appearance to adults, but their bill is not fully orange. And the eye and eye-ring are not as bright.

There are 11 species of Oystercatchers worldwide, but only 2 in North America. In the U.S. the American Oystercatcher lives on the east coast while its cousin, the Black Oystercatcher lives on the west coast. Oystercatchers specialize in eating shellfish, including oysters, clams and mussels. They are able to open the shells by using a couple different methods. Sometimes they slam the hinge of the shell on a rock. Once the hinge is broken, it’s all over for the shellfish. The other method is by using their bill as a chisel – sliding the bill into a slightly opened shell. Once they have their bill wedged in the shell, they pry the shell open with their beak. On rare occasions, a large mollusk attached to a rock, or buried deep in the sand will clamp down on a beak, and the bird will not be able to open it, or escape from the shellfish. If the tide then rises, the bird can drown.

While many bird species have very predictable migratory routes, the American Oystercatcher can be very unpredictable. After the breeding season is over, adults might move to a location hundreds of miles away, or remain in the same location. If they do re-locate, the young do not follow them to wintering grounds, as is the case for many other shorebirds. The young from a single nest might head off in many different directions. Also, not at all typical.
The American Oystercatcher is strictly a coastal bird, so you will have to leave Austin to see one. Bolivar Flats and Galveston’s East Beach are great places to find and observe it. But, this species can sometimes be difficult to find. The U.S. population is only around 14,000. The 2025 State of the Birds report lists American Oystercatcher as a Yellow Alert Tipping Point species, meaning that it has lost more than 50% of its population in the past 50 years. The good news is that the current population appears to be stable or rising.

The best time of day to see this bird is at low tide, when all the shellfish are exposed. Low tide is prime hunting time for almost all shorebirds. While most shorebird and gull identification can be very difficult, finding an Oystercatcher in the sometimes large flocks of birds on the beach is super easy. Just look for the clown face.
Adult – September
