Green-backed Tailorbird Orthotomus chloronotus

A small, long-billed, long-tailed bird of dense tangled undergrowth in lowland and foothill forest and bamboo in northern Luzon. Has olive-green wings, back, and tail, a pale gray belly, a gray chest with streaks, a rufous cap reaching below the eye, and orange legs. Very similar to Gray-backed Tailorbird, but has a white throat and a green back. Gives an explosive note followed by a rattling trill, “jwit! brrrrrrrrrr,” or a sharp note and a descending trill, “wik! Briii-yat!”
