Identify these striking shorebirds with a quick look at their bill — a thin, long, upturned beak like a swipe of ink contrasts beautifully against the bird’s habitat and feathers. Adults in breeding plumage feature reddish-orange coloring on the head and neck, while juveniles and nonbreeding adults switch the ruddy colors for light gray.

The American avocet’s white breast makes its black-and-white wings stand out. In flight, the black stripes on its back become visible. Interestingly, females’ bills frequently feature a more pronounced curve than males’. Adults are about the size of a crow or mallard.

Range and Habitat

Look for American avocets on coastlines in winter.

Keep an eye out for an American avocet in the West during breeding season, especially in Montana, Colorado, Wyoming, and New Mexico. In winter, birders can find them along the Gulf Coast. They have year-round habitat on parts of the California coast. Some birds migrate through the Midwest and the East, wintering along the Atlantic coast.

To locate an American avocet, search along beaches, lakes, and ponds. These birds tend to favor shallow waters and salty or alkaline — rather than freshwater — lakes. They tend to prefer open areas with minimal vegetation.

Diet: What Do American Avocets Eat?

These birds swish their bills through the water to find small aquatic prey.

American avocets dine on insects and other small prey that lives in or around water. Usually, this includes larvae, beetles, water fleas, brine shrimp, or small fish. They also occasionally eat seeds. To hunt, they peck or probe at the water or the wetland bottom. They also use a technique called “scything,” which involves swishing their bill in the water.

Nesting Habits

American avocets perform a mating and bonding ritual of crossing their beaks.

During courtship, watch for avocets engaging in posturing. Before breeding, the male dips his bill in water to to preen, then the pair intertwine their necks and cross their beaks.

These birds nest in colonies located on the ground. Typically, these colonies spring up on coastlines. Males and females choose the nest site together. A typical clutch size consists of three or four eggs, and only one brood is laid per season. The incubation period lasts from half a month to a month. Young leave the nest soon after hatching. Similarly to killdeer, American avocets employ a “broken-wing display” if a colony is approached by a perceived threat.

American Avocet Calls and Sounds

American avocets give a kleet or wheep call, usually only when encountering a disturbance. To hear the American avocet’s call, listen to the recording from Cornell’s Macaulay Library.
