White-collared Foliage-gleaner Anabazenops fuscus

Large foliage-gleaner with a wedge-shaped bill. Found in the middle and lower levels of forests with bamboo where it acrobatically hangs upside-down on branches and searches for prey in clusters of dead leaves. Note the dark-brown face that is set off with a prominent pale eyebrow, a pale eyering, and a white collar. It is olive-brown on the back with a buff belly and rufous tail. The song is a loud and fast series of “jek-jek-jek” notes.
