Whimbrel

The Whimbrel is a medium-sized curlew found across much of the Northern Hemisphere, breeding on Arctic and subarctic tundra and undertaking long-distance migrations to coastal wintering grounds on nearly every continent. It is best known for its striped crown pattern and rapid, staccato whistled call, often given in flight. Its bill is shorter and less dramatically curved than the Long-billed Curlew's, giving it a somewhat more compact silhouette.

Whimbrel feathers are grayish-brown to buffy-brown, marked with dark brown barring and blotching that creates a mottled, cryptic pattern. Crown and head feathers show a distinctive pattern of dark lateral stripes separated by a pale central stripe, a feature unique among most curlews and useful for identifying head feathers specifically. Flight feathers are dark brown with pale buffy notching on the edges, less warm-toned than Long-billed Curlew. Underwing coverts are grayish-buff rather than richly cinnamon. Tail feathers show narrow dark bars on a grayish-buff ground. Overall the plumage reads cooler and grayer than the warm cinnamon tones of Long-billed Curlew.

Sexes are similar in plumage, with females slightly larger. Juveniles show finer, more spotted buff fringing on the wing coverts and scapulars compared to the coarser barring of adults. There is minimal seasonal color change. A full post-breeding molt occurs primarily on wintering grounds, with flight feathers replaced sequentially over an extended period, sometimes overlapping with the next breeding migration in some individuals.

Breeds on Arctic and subarctic tundra, including wet sedge meadows and hummocky ground across northern North America, Europe, and Asia. During migration and winter, Whimbrels use coastal mudflats, rocky shorelines, sandy beaches, and mangrove-lined estuaries across a vast wintering range spanning coastlines of the Americas, Africa, and Asia-Pacific. It is one of the most widely distributed curlews, undertaking long nonstop oceanic flights during migration.

Whimbrels forage by probing mud and sand for crustaceans, particularly fiddler crabs in some wintering areas, and also pick insects and berries on the tundra breeding grounds. Nests are shallow ground scrapes on tundra, camouflaged among low vegetation, with both parents attending the nest and young. The flight call is a rapid, evenly spaced series of whistled notes, often described as a titter, distinct from the rising two-note call of Long-billed Curlew. Whimbrels are known for remarkable long-distance nonstop flights during migration. Conservation status is IUCN Least Concern.
