Yellow-eared Barbet Psilopogon australis

Small leaf-green barbet, endemic to Java and Bali. Note bright sky-blue patches on face, shoulders, and undertail, as well as a bright yellow patch below each eye. Inhabits lowland and foothill forests, as well as forest edge. Like other barbets, can be difficult to see: listen for its song, an insect-like series of notes, given in groups of four. Also gives a high “whew’ew” and sharp pips.
