The behavior of Dusky Hummingbird is not described in much detail. This hummingbird forages at mid- to upper strata in trees, and persistently wags and spreads the tail when feeding (Howell and Webb 1995).

Wagner (1946) observed Dusky Hummingbirds capturing small insects at "the burst open fruits of the candelabrum cactus (Cephalocereus)" and at blooming Inga trees.


No information.

Sexual Behavior

Little information. Dusky Hummingbird presumably is polygynous, as are most if not all species of hummingbirds (Schuchmann 1999: 509).

Social and interspecific behavior

Dusky Hummingbird usually is solitary, as is typical of hummingbirds.


No reported instances of predation on Dusky Hummingbird?
