Tooth-billed Wren

Overview

The tooth-billed wren (Odontorchilus cinereus) is a species of bird in the family Troglodytidae found in Bolivia and Brazil. It is a monotypic species that shares its genus with the grey-mantled wren.

Identification

• Adults measure 12 cm (4.7 in) in length with an approximate male weight of 11 g.
• Plumage features a grayish cinnamon crown, grayish brown face, and medium gray back, with buffy gray throats and breasts and pale buff bellies.
• The typical song is described as a short, simple trill sung by both sexes.

Habitat

Found primarily in Brazil but extending slightly into the Santa Cruz Department of Bolivia, the species inhabits tall humid lowland forest at elevations up to 600 m (2,000 ft). Its range is located south of the Amazon River, between the Madeira River on the west and the Xingú River on the east.

Diet

Although its diet is not known in detail, the tooth-billed wren is insectivorous. It forages in the canopy 15 to 30 m (49 to 98 ft) above ground by exploring and probing foliage along branches and in vine tangles, usually as part of a mixed-species foraging flock.
