Standard-winged Nightjar

A sparrow-sized dark warbler with an often scruffy-looking, graduated tail. Has dark chestnut-brown upperparts, a whitish eyebrow, a distinct white throat, and dull grayish underparts. Formerly grouped with Buru Bush Warbler and Seram Bush Warbler under the name “Chestnut-backed Bush Warbler.” A secretive inhabitant of montane and foothill forest, often creeping around on or near the ground. Darker above and dingier below than Gray’s and Middendorff's Grasshopper-Warblers, and also has a clean-cut white throat; almost identical to Sulawesi and Seram Bush Warblers, but ranges do not overlap. Calls include a sharp metallic “chit” and a drawn-out, wavering buzzy note, “tzeeoooreee.” There is some variation in songs, which usually comprise three high-pitched buzzing notes, “tzeeee-tzeee-tzeee,” higher-pitched on the final note. Song includes a high, liquid-sounding “tzi-tzee”, as well as a longer, more repetitive “tzi-tzee, tzi-tzee, tzi-tzee.”

Fairly large tanager found in open habitats in lowlands and foothills below 1,500 m. Male is all black with contrasting rump varying from lemon yellow to red. Female is dark blackish-brown above and yellow below, sometimes with an orange breast band. She also has a contrasting rump varying from lemon yellow to red. On both sexes, note stout silver bill with dark tip. Common and conspicuous in clearings, gardens, shrubby areas, and second growth, usually in pairs or small groups.

Mostly dark grayish-brown with a pure white undertail, a black tail, a variable white or smudgy pale throat, and a fleck of white behind the eye. Long tail is often fanned. Prefers primary and secondary rainforest, but tolerates plantations and gardens. Common call is a quiet twitter. Sometimes imitates other bird species.
