Patagoniensporntyrann Lessonia rufa

Tiny little terrestrial flycatcher, common in open habitats of southern South America in summer, migrates north in winter. Feeds mainly by hopping on the ground, but perches readily on posts, fences, and low bushes. During migration times, sometimes found in small flocks mixed with other migrants of open country. No similar species in range: male is black with bright rusty back. The much plainer female is easily overlooked, but size, shape, and behavior distinctive, and is often with males.
