Weißbrustnonne Heteromunia pectoralis

Small, grayish-brown bird with a scaly white bib, a dark black facial mask, buffy belly, and a gray bill. Juveniles very plain brown, with faint outline of adult's mask. Inhabits dry grasslands and edges of wetlands across northern Australia, including spinifex, and sometimes wanders far from core range. Gives a distinctive “teet” in flight or sparrow-like chip note.
