The buff-bellied hermit is found in the eastern Andean foothills of Bolivia from southern Beni to eastern Santa Cruz departments and into the Brazilian states of Mato Grosso and Mato Grosso do Sul. It has also been recorded as a vagrant in Paraguay. It inhabits the understory of several landscapes including deciduous and semi-deciduous forest, secondary forest, open woodland, and shrubland. In elevation it ranges from 150 to 800 m (490 to 2,600 ft).
Observations of the buff-bellied hermit in eastern Bolivia showed no evidence of movement.
The buff-bellied hermit feeds on nectar from a wide variety of flowering plants and also on small arthropods.
The buff-bellied hermit's breeding season has not been conclusively determined, but observations hint that it is during the November to April wet season. Males congregate at leks. The nest has not been described.
The IUCN has assessed the buff-bellied hermit as being of Least Concern, though its population size is unknown and believed to be decreasing. It is locally common but "oorly known, and should perhaps be classed as Data Deficient."
