Black-faced Solitaire

Overview

The black-faced solitaire (Myadestes melanops) is a bird in the thrush family endemic to highlands in Costa Rica and western Panama.
This is a bird of dense undergrowth and bamboo clumps in wet mountain forest, normally from 750 to 3,000 m (2,460 to 9,840 ft) altitude. It disperses as low as 400 m (1,300 ft) in the wet season, when it may form loose flocks. It builds a cup nest of mosses and liverworts in a tree crevice, hole in a mossy bank, or concealed amongst mosses and epiphytes in a tree fork up to 3.5 m (11 ft) above the ground.
