Citron-crested Cockatoo

This flightless South American relative of the ostriches stands about 5 feet tall with a body about the size of a sheep; no similar species in its range. Rheas roam widely on open Patagonian steppe and also occur locally in open habitats of the Andes, mainly at very high elevations. Can be confiding where used to people, but in other areas wary, running strongly and quickly. Rheas occur singly or in groups, and males take care of the young. Adults have bold pale spots on the body, first-year birds are plainer overall.

Scarce flycatcher found along the west slope of the Andes in northern and central Peru. Like other chat-tyrants, it features a black mask and a long white eyebrow. Chestnut wing stripes and the lack of any yellow in the eyebrow help separate it from other species in range. Inhabits dry and semi-humid forest. Typical song is a dry, toneless trill, sometimes with a staccato quality.

Little-known medium-sized owlet-nightjar restricted to the mountainous Karimui Basin of eastern Papua New Guinea. Dark gray overall with fine barring; note chevrons on breast, thick black “eyebrows” that wrap around the head, and a black crown stripe extending down between the eyes; compare with other quite differently-marked montane owlet-nightjars, such as Mountain and Feline. Vocalizations poorly known.
