Gray-chinned Hermit

A small, inconspicuous hermit hummingbird of dry and humid forests in the Andes from Colombia to Bolivia, gray-chinned hermits have brownish upper parts, grey chin, and pale buff underparts with a white-tipped central tail — a subtle palette compared to many hummingbirds. They inhabit forest understorey and shrubby forest edge at elevations of 300–1,600 meters, following systematic trap-line routes to visit flowering plants. Males gather at leks to attract females through persistent vocalization.
