Slender-billed Parakeet

A small stonechat-like bird with a relatively long, slim bill. Male has blackish upperparts, a dark face, a white chin, and a whitish, contrasting eyebrow. Breeding males are darker and more contrasting overall than nonbreeding males. Females are brownish overall, with pale underparts, a pale eyebrow, and a lightly streaked brown back. Both sexes often forage on the ground, where they perform a strange “puff-and-roll” display, which involves puffing out the chest and moving from side-to-side. Rare, found in dry, arid scrubland.

Very small but stocky, quail-like bird of Patagonian steppe, sandy and stony plains in the Andes, coastal dunes, and deserts. Found in pairs or small groups; locally large flocks in nonbreeding season. Male has hooting song given from low mounds or fence posts, and sometimes during display flight. Flight is strong and fast; flushes with loud bleating chatters. Similar Gray-breasted Seedsnipe is larger, favors rockier Andean habitats, and has plain gray breast without diagnostic black Y pattern present on male Least Seedsnipes.

Large night bird with a remarkably big head. Plumage is variable, ranging from grayish to strikingly rufous, but always intricately patterned. Very similar to Whip-poor-will but larger, longer-winged, and more rufous. Chuck-will’s-widow has less white in the tail than Whip-poor-will, but can be difficult to see. Strictly nocturnal, more often heard than seen. Listen for a loud whistled song calling its name: "chuck-WILL'S-widow." Sometimes found roosting on low branches during the daytime, especially during migration. Found in forests with mix of pines and deciduous trees.
