Rotflankenkolibri Oreotrochilus adela

Beautiful and distinctive hummingbird of Polylepis woodpland and adjacent scrub in the high Andes from the Argentina-Bolivia border to Cochabamba. Fairly rare. Male is the only hummingbird in range with a combination of rufous sides, black breast, and green throat. Female can be distinguished from other species of hillstars by her orange underparts.
