Andean negrito Lessonia oreas

Tiny little terrestrial flycatcher, fairly common locally in open habitats of the high Andes, especially bogs and lakeshores. Feeds mainly by hopping on the ground, but perches readily on posts and fences. No similar species in range: male is black with a bright rusty back; female is dark sooty brown with a dull rusty back. In flight both sexes show whitish flash in wings (absent in Austral Negrito, which occurs in lowlands to the south).
