At first look, the Willet is a rather drab and nondescript medium-sized shorebird found in wetland habitats and nearby uplands. However, further observation reveals subtle patterning in its relatively uniform grayish plumage and birds in flight expose a distinct, bold white wing bar that contrasts with a black border. Sexes are similar in appearance at all times of the year.
Willet are present on breeding grounds in Oregon for a short period of time during spring and summer, but displaying birds are conspicuous and emit a loud and persistent "pill-will-willet" call. These vigilant and vocal individuals often hover overhead and alight on fence posts or the tips of bushes near nesting territories. They are a common spring and summer resident east of the Cascades in Klamath, Lake, Harney, Malheur, and Grant counties.
