Glossy-backed Becard

Small hummingbird found in dry, scrubby regions of the Andes; also in coastal deserts in Peru. Male has a glittering blue throat bordered below by purple. Female lacks this and has a rusty wash on white underparts; the extent of this rusty color varies between individuals. Also note slightly curved bill. Male performs swooping U-shaped display flights, alternately giving high-pitched twitters and low-pitched mechanical sounds while doing so. Not known to visit feeders.

A glossy-black starling with a big permanently raised crest that gives it a unique, broad-headed profile. Also note prominent whitish markings on sides of neck and breast, which appear like one large patch. Juvenile shorter-crested, with a brown chin and a bicolored bill. Frequents the canopy of lowland and hill forest in small groups or pairs, preferring pristine areas, but straying into edges and degraded patches too. Complex song involves whirring “weee-ow-weee-ow” mixed with “chur” and “chip” notes. Also gives a single, strident metallic “chip” call.

This antwren is known only from a small area in northeastern Peru and adjacent border areas of Ecuador. It is confined to rainforest that grows in nutrient-poor soils with a specific mineral composition. Note the yellowish underparts, black crown and black eye-stripe separated by a pale eyebrow, and bold white wingbars and tail edges. Similar to Dugand’s Antwren, but male has yellowish underparts and female has a black (not brown) crown. Stays quite high in the trees and often joins mixed-species flocks. Song is decelerating series of notes that rises and then falls.
