Wilson's Snipe

Overview

Wilson's Snipe is a stocky, long-billed bird of freshwater marshes and wet meadows across North America, more often heard than seen due to its outstanding camouflage and secretive habits. It is closely related to the Common Snipe of Eurasia and was until relatively recently considered the same species.

Feathers are usually found in dense marsh or bog vegetation, and the species' narrow, specialized outer tail feathers are a particularly distinctive find.

Feather Identification

• Upperparts: intricate patterning of black, brown, and buff, with bold cream-colored stripes running down the mantle and scapulars, providing exceptional camouflage in marsh vegetation.
• Outer tail feathers: narrow, stiffened outer tail feathers that vibrate in fast diving flight to produce a distinctive winnowing sound; these differ from the broader, more typical central tail feathers.
• Underparts: barred flanks with a whitish belly, contrasting with the darker, more mottled upperparts.
• Versus Common Snipe: extremely similar; Wilson's Snipe typically has slightly narrower white trailing edges on the secondaries and a marginally different number and width of outer tail feathers, subtle differences generally only reliably assessed in the hand.

Plumage Notes

Adults show intricate camouflage patterning year-round, with bold buff-and-black mantle stripes and finely barred underparts; sexes look alike, with no strong seasonal plumage change. Juveniles resemble adults closely, showing a similarly patterned but sometimes slightly less contrasty plumage when very fresh.

The complete molt typically occurs after the breeding season, with body feathers replaced gradually; the specialized outer tail feathers used in winnowing displays are molted along with the rest of the tail.

Habitat & Range

Wilson's Snipe breeds across a wide swath of North America, from Alaska and Canada south through the northern United States, in wet meadows, bogs, and marshes. Many populations migrate south for winter, wintering across the southern United States, Mexico, and parts of Central America, while some populations in milder regions remain resident year-round.

Behavior & Field Notes

Wilson's Snipe forages by probing deeply into soft mud with its long, flexible bill, taking invertebrates from wet soil. It relies heavily on camouflage and freezing behavior to avoid detection, flushing suddenly with a sharp call when approached closely.

During courtship display flights, males dive steeply through the air, using specialized outer tail feathers to produce a distinctive winnowing or drumming sound rather than a vocal call. Nests are well-hidden scrapes in dense marsh vegetation. Feathers, especially the narrow winnowing tail feathers, are a strong identifying find in wetland habitats.
