White-capped Tanager

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.”

Long-legged songbird found in semi-arid parts of southern Australia. Grayish above, paler gray below, with faint wingbars and long tail, often flicked upward. Very subtle dark mark through the eye and cheek. Usually seen running around on the ground in open woodland, although male also sings from higher perches. Main call is a repeated three-note rising whistle, "chip-dee-deee," but also makes rough, buzzy alarm calls.

Distinctive streaky brown bird of riverine habitats of the Orinoco Delta. Most of body brown with buffy streaks (tear-shaped on underparts). Rich chestnut on chin, wings, rump, and tail. Sexes similar. Locally common and often in pairs, found from understory to canopy in riverine forest where often climbs trunks like a woodcreeper. Voice is an explosive group of short notes, mostly in duet. Similar to Orinoco Softtail (no range overlap), which is less streaked and has a buff eyebrow; Rusty-backed Spinetail is unstreaked. Endemic to the Orinoco River of northeastern Venezuela.
