White-browed Robin

Adult is unique, a vision in glossy black and pale pink. Juvenile is brown with an orange bill. Breeds in colonies on steppes and winters in open and wooded habitats. Gathers in huge numbers to roost, often mixing with other species at roost sites. Flocking birds keep up a constant cacophony of dry chattering calls. 

Large, streaky tinamou of upper elevations of the east side of the Andes. The highland version of Red-winged Tinamou, similar in voice and habits. Fairly rare and local in tall grass in the high Andes from NW Argentina to the La Paz area in Bolivia. Prefers steep hillsides and slopes, largely absent from the altiplano. From other montane tinamous by characteristic plaintive, two part whistled song, for which it is named (“HUAY-co”). Shy and retiring, can be quite difficult to see, most often found by voice.

Hardly bigger than a sparrow, this odd little ground bird has a disproportionately loud song. The booming hoots the female gives during the breeding season are often the easiest way to find this species in the open grassy habitats it occupies. Females are more vividly colored than males, with a bright orange breast and nape, yellow belly, white throat, and speckled gray upperparts. Males have a faded version of the same general color scheme, but have less spotting on the breast and a tan throat.
