Kahverengi Gerigon Gerygone mouki

Small plain bird with thin bill. Upperparts brown, underparts whitish, with gray face, red eye, and distinctive patch of white in undertail. Juveniles lack red eye and have yellow gape (base of bill). Inhabits rainforest, wet forest, and surrounding habitats of eastern Australia. Song a rasping "which-is-it," very different from tinkling notes of Mangrove Gerygone.
