Obi Paradise-crow

A sparrow-sized, resident pipit with brown plumage that varies in tones in different parts of its range. All birds have a bi-colored bill with a curve to the tip of the upper bill. The breast is streaked and the upperparts have variable amounts of streaking. Juveniles show distinct and dark mottling on the upperparts. It is common in open habitats such as wetlands, farms, fields, and even large parks. Very similar to Blyth’s and Richard’s Pipits, but relatively compact and has a more distinct eyebrow, fainter or no streaking on the back of the neck, a larger head, and a shorter tail than either Blyth’s or Richard’s. Calls include short “tsip” and “tissip” notes.

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.

Inconspicuous and rarely seen bird of rainforest canopy. Small and slender with a long tail; mostly dark gray with a broken white eyering, white belly, and white outer tail feathers. Inhabits canopy of tall forest, especially in regions with sandy soils, and also occurs in shorter-stature forests on white sand. Usually seen with mixed-species flocks as it forages actively in outer foliage, sallying for insects and gleaning from leaves, moving long tail from side to side, like other gnatcatchers. Thin and indistinct call notes are easily overlooked among calls of other species in flocks, but distinctive shape, active behavior, and long tail with much white should clinch identification. Distinguished from Tropical Gnatcatcher by uniform gray body plumage and lack of a black cap.
