Common, medium-sized mostly brown hummingbird of rainforest understory; also occurs in secondary forests. Moves constantly among widely separated patches of flowers, pausing en route to investigate brightly colored objects, including clothing. Typical call is a loud, single squeak, given as birds move between foraging spots. Displaying males occupy low perches and give a long series of squeaks while pumping their tails. Similar to several other hermits in general appearance and behavior; note lack of white tips on outer tail feathers, curved bill, and generally brownish coloration without strong facial markings.
