Rusty-browed Warbling Finch

Shy antshrike found in understory of lowland and foothill rainforest. Male is dark gray or black; he also has small white dots on the shoulder and a white line at the bend of the wing, but these features are not always evident in the field. Female is plain brown; on the western edge of the range, she also has a black face, throat, and tail. Usually first detected by voice: song is a soft series of evenly spaced, nasal caws.

Large turkeylike bird found in extensive areas of sagebrush. Both sexes gray overall with very fine patterning, black belly, and long pointed tail. Males have a white breast and a black throat. Spectacular male display involves fanning tail, inflating yellow air sacs on chest, and thrusting them forward to produce liquidy popping noises. Extremely similar to more widespread Greater Sage-Grouse but smaller and no range overlap. Also note lighter tail and longer head plumes on Gunnison when displaying. Most easily seen at display sites in early spring; can be very inconspicuous at other times of year. Tends to forage in wet riparian areas near sagebrush. Population in decline.

This hummingbird is found in humid forest in mountainous regions of eastern Venezuela, the Guianas, and northern Brazil. Plumage is bright green with a coppery rump and tail, and belly ranges in color from pale gray to buff. Occasionally seen in lowlands, where it is perhaps just a seasonal visitor or wanderer. Formerly considered to be a subspecies group of Green-bellied Hummingbird.
