Xingú River on the east. It inhabits tall humid lowland forest at elevations up to 600 m (2,000 ft).^[2]

Behavior

Feeding

The tooth-billed wren's diet is not known in detail, but the species is insectivorous. It forages in the canopy, 15 to 30 m (49 to 98 ft) above ground, exploring and probing the foliage along branches and in vine tangles. It usually is part of a mixed-species foraging flock.^[2]

Breeding

Vocalization

The tooth-billed wren's typical song is "a short, simple trill" [1]; both sexes sing it.^[2]
