Crested Oropendola
Psarocolius decumanus
Large blackbird with thick triangular bill. Dark blackish plumage, fading to paler reddish-brown at rear. At a distance, appears all black. Striking yellow tail and pale blue eye. Separated from other oropendolas by combination of large size and dark color. Often found in loose flocks anywhere with some trees, including forests, edges, and even disturbed open habitats. Oropendolas are colonial nesters that build hanging woven nests. Listen for bizarre gurgling noises.

Lemon-rumped Warbler
Phylloscopus chloronotus
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!”
Striped Kingfisher
Halcyon chelicuti
A small and dainty woodland-dwelling kingfisher with powder-blue tail and flight feathers, creamy collar, dark eye-stripe, and streaky brown crown. Singles and pairs are inconspicuous in the mid-canopy of parkland-like savanna and woodland, preferring more arid thornveld than other dryland kingfishers. It draws attention to itself with a loud, ringing “teeep-tiiii-rrrrrrr” and rollicking “trrreerrr-treeerr-treeer” calls.
Olive Manakin
Xenopipo uniformis
An inconspicuous, small, green bird of the tepui highlands. Key marks are entirely olive-green plumage and yellowish eyering. Inhabits humid, mossy forest undergrowth on tepui slopes, most commonly above 800 m but occasionally lower. Generally solitary, quiet, and easily overlooked; most likely to be seen feeding at fruiting shrubs. Calls include a high, wheezing note that may rise and fall in pitch. Distinctive eyering should easily separate this species from other manakins at higher elevations in the tepuis. Below 800 m, told from Olivaceous Schiffornis by smaller size, shorter tail, and strongly olive-green plumage. Told from female Black Manakin by eyering and olive plumage.
