St. Vincent Wren

A small, chunky, wren-like understory warbler that often leans forward and cocks its short tail. This species has brown eyes, olive-green wings and tail, and white underparts. Found in evergreen forest understory, plantation, and thickets along the Angolan escarpment. Usually in pairs, hopping about, often low to the ground, searching for small insects. The two common vocalizations are a nasal “meehrrp” alarm call and a strident repeated snapping “strik-strik-strik-strik-strik” song. Very similar to Green-backed Camaroptera, but tail is brighter green, rather than gray or gray-green, and underparts are cleaner white, rather than grayish, especially on the breast. 

Small, warbler-like flycatcher found in the Andes and coastal hills. Mostly gray and white with whitish wingbars, white eyebrow, and rufous wing patches. Similar to Rufous-winged Antwren but lacks yellow on belly and has a gray crown. Actively forages at middle to upper levels of forest, and may join mixed-species flocks. Gives quiet but sharp notes, either alone or in a short series. Erratic in its occurrence and may seemingly be absent from some sites for months at a time; its movements have not been studied extensively.

A slender, long-tailed bird of dense gallery forests and river islands in northern Brazil and extreme southwestern Guyana. Male is mostly black with tail feathers tipped white and with white scalloping on wings. Female is very different: brownish-gray above and buffy below, with a black tail and white throat streaked black. Like other Cercomacra, tends to stay concealed in dense vine tangles in the canopy and midstory, where it clambers slowly about, usually in pairs, searching for insects. Best detected by voice; two-noted song is given in series of 3–5 phrases, with hiccupping effect; similar to song of Gray Antbird but higher-pitched, faster, and less hoarse. Female is unlike any other species in range. Male is darker than Gray and Blackish antbirds, which do not occur in the same habitat and have different voices. Plumage recalls Dot-winged Antwren, but Rio Branco Antbird is considerably larger.
