White-bellied Woodstar

A tiny woodstar hummingbird inhabiting the Andes and inter-Andean valleys from Colombia to Bolivia, white-bellied woodstars are among the smallest hummingbirds with males weighing just 2.5 g. Males display a vivid amethyst-purple gorget and white belly with green flanks. Found at forest edges and gardens from 1,500–3,500 meters elevation. Despite their diminutive size, they are aggressive and highly maneuverable, entering torpor at night to conserve energy in cold Andean conditions.
