Giant Babax

Striking tanager of open woodland, consisting of two relatively distinctive subspecies. Distinguished from other warbling-finches in range by its black breast band. Nominate torquatus is a resident of the southern Bolivian Andes, especially open scrub and cactus forest of the dry valleys. Migratory pectoralis shows a thicker breast band and darker undertail coverts, and breeds in the Pampas, Monte, and northern Chaco dry forests in north central Argentina, dispersing north to lowlands of W Paraguay and SE Bolivia.

One of the iconic birds of the Andes. Fairly large, significantly larger and chunkier than a thrush. Found in cloud forest at middle elevations, most often at a dawn display site where males make piglike squeals and jump and dance for females. Sometimes seen elsewhere in the forest, especially at fruiting trees. Males can be either brilliant crimson or orange, always with black wings and broad silver tertials, orange legs, and puffy rounded crest. Female duller brown with smaller crest; note staring pale eye. Nests on large rocks or cliff faces. Only similar species is Guianan Cock-of-the-rock, but no range overlap.

Medium-sized sunbird with strikingly different breeding male and female plumages. Breeding males are green on the head and back, with a purple band across the breast. There is much regional variation; the belly can be yellow-orange, yellow, or white, though it is yellow across most of the range. Some subspecies also show extensive purple onto the throat. Females and non-breeding males are plain olive-brown on the back and dull yellow below. Found in a broad range of habitats, from arid thornscrub to moist savanna, gardens, and forest edge. Vocalizations typical of a sunbird, and include a quick jumbled song. Similar to Collared Sunbird, but larger, with a longer and more curved bill.
