Green-backed Flycatcher

Small leaf warbler with many extremely similar relatives. Like other “Pallas’s-type” leaf warblers, has olive-yellow upperparts, pale underparts, prominent brow and crown stripes, double wingbars, and a pale rump. Unlike Ashy-throated and Buff-barred Warblers, lacks any white on outer tail edges. Pallas’s averages yellower-headed and brighter overall. Gansu and Chinese Leaf Warblers can be incredibly similar, but Lemon-rumped averages whiter-browed and yellower-bellied than the former, more contrastingly-marked on the head than the latter, and darker-billed than both. As with many other physically similar leaf warblers, best distinguished by voice and habitat. Breeds in coniferous and mixed forests at mid- to high-elevation forests, though may descend into foothills in the winter. Two song types are both highly distinctive; one is a buzzy, descending rattling trill and the other is a series of high-pitched clicking twitters. Call is a loud, strident pair of notes: “pse-tew!”

Small songbird with long, pale-tipped tail, slim bill. Grayish brown above, pale below, with striking red-brown rump and white throat with black border, speckled at lower edge. Frequently cocks and fans tail. Actively forages near the ground in wetter areas with dense vegetation, including mangroves. Song is a short, descending series of high-pitched squeaks. Calls include a metallic “pink!” Previously considered the same species as the now-split “Rufous Fantail.”

Males are unmistakable snow-white cotingas with a greeny-blue bare face and throat. Females are olive-green above with a streaked belly and gray-brown head. The song is a metallic, explosive and massively loud “boink” delivered from high perches in the canopy of humid forests.
