Swainson's Warbler vs White-rimmed Warbler

Swainson's Warbler

Limnothlypis swainsonii

Small19 gShrubland

Swainson's warblers are a small and rather undistinguished songbird, though they are fairly large for a New World warbler. Adults grow to 12.5–16 cm (4.9–6.3 in) in length and 11–20.5 g (0.39–0.72 oz) in weight. The wingspan averages 23 cm (9.1 in). They are a plain olive-brown above and pale yellow-white below. They have a whitish eyebrow stripe that runs above their eye, and the top of their head is a rusty brown. Unlike most other New World warblers that are mostly dimorphic, there is no difference in appearance between a male or female Swainson's warbler.

White-rimmed Warbler

Myiothlypis leucoblephara

Small15 gForest

The white-rimmed warbler is about 14.5 cm (5.7 in) long and weighs 14 to 21 g (0.49 to 0.74 oz). The sexes have the same plumage. Adults of the nominate subspecies have a mostly gray head with a blackish gray stripe in the middle of the crown, a white stripe above the lores, a thin black line through the eye, white crescents above and below the eye, and whitish cheeks. Their upperparts, wings, and tail are olive-green. Their throat and underparts are mostly whitish with a gray wash on the sides of the breast, an olive wash on the upper flanks, and pale olivaceous-yellow undertail coverts. Voice: The white-rimmed warbler's song is a "fairly long series of fee notes, which start at extr. high level and then descend very steeply to 5 notes lower. Its call is "a sharp penetrating pseeyk".
