Baird's Sandpiper

Small, active, bright yellow warbler. Most birds (adults of both sexes and young males) have a black cap; young females lack this feature. Also note the rather long, narrow tail that is actively flipped around while foraging. Extensive breeding range across northern and western North America; more common in the west than east. Prefers dense thickets, especially with willows and alders. Winters primarily in Mexico, extending as far south as Panama. Migrants and wintering birds are found in any brushy wooded habitat. Listen for husky chip notes. Compare with Yellow Warbler, but note Wilson’s is smaller, smaller-billed, and has a relatively longer, thinner tail.

More of a soft blush than a burning flame, the red patch on the male’s face is nonetheless unique. The female lacks the red patch, but is still distinctive in her size, small sharp bill, and pale wingbars. Both sexes are yellow above and pale gray below, with the male being more predominantly yellow than the female. Found in montane broadleaf forest at middle to high elevations, sometimes mixed in with other species; some populations descend to lower foothills and lowlands in the winter. Song is an undulating series of twitters, chips, and trills; also twitters and trills when flocking.

A tiny, stubby, plump dark songbird with a bold red throat in males. Female is nondescript, all gray with a clean white throat. Juveniles resemble female but have a pale-based bill and a green-washed breast. Singles and pairs can be found in lowlands and foothills in a variety of habitats, including forest, forest edge, scrub, and gardens. Male can be separated from male Crimson-crowned Flowerpecker by red throat and lack of red crown. Female Gray-sided differs from female Crimson-crowned in absence of red rump. Song is a thin, high-pitched “see-se-sooo.” Also gives a buzzy “tzjit” note.
