Mountain Fulvetta

Overview

The mountain fulvetta (Alcippe peracensis) is a 14 to 15.5 cm long species of bird in the family Leiothrichidae. It is found in Cambodia, Laos, Malaysia, Thailand, and Vietnam in subtropical or tropical moist montane forests.
The black-browed fulvetta, Alcippe grotei, is sometimes considered to be conspecific with mountain fulvetta, but the two forms differ in morphology and vocalisations, and are separated altitudinally. Black-browed fulvetta occurs primarily below 400 m, and mountain fulvetta above 900 m.
