Fearful Owl

A relatively small swallow of western North America. Adult males have a white face and show turquoise-green upperparts and a purple rump in good light. Females and immatures are duller on the upperparts, sometimes just dusky-gray. In flight, note the prominent white "saddlebags" extending up from the underparts to the sides of the rump. Fairly common in a variety of open habitats, often foraging over meadows or ponds. Can be seen in large flocks, sometimes mixed with other species of swallow. Breeds as far north as Alaska; winters primarily in Mexico and northern Central America.

Chunky finch-like tanager of high elevations. Males are yellow with a gray head, wings, and tail; females are similar but duller. Found in a variety of dry, open habitats including scrub, agricultural areas, and Polylepis woodlands. Often forages in groups on the ground, and may associate with other sierra-finches and similar species. Distinctive within its range; replaced by the similar Black-hooded Sierra-Finch farther south.

A small, sharp-billed warbler-like bird that is saturated with yellow. Note the yellow underparts, olive-yellow back, and bold white spectacles around the eyes. Found in forest, savanna, scrub, gardens, moist woodland, and plantations, usually in hyperactive flocks that can contain many individuals. Often joins mixed flocks with other small birds. Most common call is a high-pitched rising rattle. Song is a quiet, chatty sequence of “chew” notes. Similar to Pale White-eye, but usually separated by range; shows more yellow above the bill, is more richly-colored overall, and prefers moister habitats. Also similar to Southern Yellow White-eye, and separation and degree of range overlap is poorly understood.
