The White-throated Gerygone is a small bird with gray-brown upperparts and bright yellow underparts.
It has a thin bill, gray-brown upperparts, bright yellow underparts, a white throat and tail spots, and a red eye. Juveniles lack the white throat and can be difficult to distinguish from Fairy Gerygone, which lacks white tail spots.
It inhabits open forest and woodland and gives a sweet, descending trill.
