Gray-headed Batis

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.

This subtly handsome finch is unique in its range; warm sandy brown with bright pink and silver flashes in the wings. Sexes are similar, but the male boasts a restricted black mask extending from the front of the eye to the base of the stout charcoal-black bill, which the female lacks. Not restricted to deserts but generally does prefer dry, open areas in middle to high altitude regions. Frequents villages, towns, and even cities. Gives a tumbling series of random-sounding notes, usually with a rather hoarse, buzzy quality. Calls include “chip” and “chink” notes and buzzy wheezes.

Small finch with bright yellow plumage; males have a black cap. Found at forest edges, in caatinga vegetation, in second growth, and even in coffee plantations. Rare; heavily exploited for the illegal cage bird trade. The song is a complex series of warbling notes. In the more common Hooded Siskin, males have a black head and females have less yellow below and are less uniform green on the head.
