Willet


Piercing calls and distinctive wing markings make the otherwise subdued Willet one of our most conspicuous large shorebirds. Whether in mottled brown breeding plumage or gray winter colors, Willets in flight reveal a bold white and black stripe running the length of each wing. These long-legged, straight-billed shorebirds feed along beaches, mudflats, and rocky shores. This one was seen on the shoreline of Dauphin Island.

Willets breeding in the interior of the West differ from the Atlantic Coastal form in ecology, shape, and subtly in calls. Western Willets breed in freshwater habitats, and are slightly larger and paler gray. Eastern Willets have stouter bills and more barring on their chest and back. The difference in pitch between the calls of the two subspecies is very difficult for a person to detect, but the birds can hear the difference and respond more strongly to recorded calls of their own type. Although both parents incubate the eggs, only the male Willet spends the night on the nest. Willets and other shorebirds were once a popular food. In his famous Birds of America accounts, John James Audubon wrote that Willet eggs were tasty and the young “grow rapidly, become fat and juicy, and by the time they are able to fly, afford excellent food.” By the early 1900s, Willets had almost vanished north of Virginia. The Migratory Bird Treaty Act of 1918 banned market hunting and marked the start of the Willet’s comeback. Because they find prey using the sensitive tips of their bills, and not just eyesight, Willets can feed both during the day and at night.
