Overview

Distribution

Range Description

Troglodytes tanneri is endemic to Isla Clarin in the Revillagigedo Islands, Mexico. Only 20 individuals were recorded in 1986 (Everett 1988), but subsequent visits to the island have found the species to be common (Howell and Webb 1989, Santaella and Sada 1991, Wanless et al. 2009). The population was estimated at 170-200 pairs in 1988, with the highest densities around buildings and adjacent areas (Howell and Webb 1989).
