Peruvian Sheartail Thaumastura cora

Tiny hummingbird of desert lowlands and foothills; found in gardens, agricultural areas with flowers, and native scrub. Adult male with long black-and-white tail “streamers” is basically unmistakable, but greatly outnumbered by females and immatures, which look much like several other small hummingbirds. On females and immatures note the relatively long tail with pale edging to the shorter central feathers and lack of rusty tones to the plumage overall.
