Chestnut-bellied Cotinga

Tiny, bubbly, buffy-colored wren of dense grassy or shrubby habitats. Fairly common but locally distributed from central Mexico to the southernmost tip of South America; surely comprises multiple species. Occurs from open grasslands and marshes at sea level up to paramo in the high Andes. Generally secretive, but perches up when singing. Generally pale brownish with complex patterning on upperparts; compare with much plainer House Wren. Variable voice, usually including harsh chips, buzzes, and trills.

A distinctive pheasant with bare red facial skin, a backward-pointing crest, and a vertically compressed tail. Males are iridescent black and silver. Females are grayish-brown. Coloration varies considerably throughout its range, with northeastern birds averaging the darkest. Occurs in forested areas, usually in hilly or mountainous regions. Overlaps with Silver Pheasant in the north of its range, with which it produces confusing intergrades. Native to South and Southeast Asia and introduced to the Hawaiian Islands of Hawaii and western Oahu. Males give a soft crow, other calls include low grunts and high-pitched squeals.

A small, warbler-like wren of Andean cloud forest. Plumage is gray and white with a barred tail and vent, brownish crown, and faint streaking on the head. When seen from below in poor lighting conditions, the barred tail is usually the best feature to look for. Stays high in the canopy and is almost always encountered with mixed-species flocks. Vocalizations are very high-pitched and include gravelly trills and siren-like whistles.
