Mrs. moreau's warbler Scepomycter winifredae

An unusual warbler with a restricted range in the central Tanzanian mountains. Mostly gray, darker on the back, with a rich rufous head and breast. Females are duller. A shy and skulking bird of the understory of montane forest. Usually found in pairs. Somewhat similar to African Tailorbird and Chapin’s Apalis, but chunkier, with more extensive rufous on the head and breast. Normally detected by voice: the male sings a well-spaced series of long, pure whistles, sometimes accompanied in a duet by the female, who gives lower whistles in simple patterns.
