White-bearded Greenbul
Criniger ndussumensis
A medium-sized greenbul often found in flocks in forest and forest edge with other bearded-greenbuls. Like all bearded-greenbuls, will sometimes puff out throat feathers. Often forages actively along trunks and large branches. Shows a grayish head, a bright white throat, yellow-green underparts, and olive-green upperparts with a reddish tail. Nearly identical to Red-tailed Greenbul, and can occur with it in the same mixed-species flocks in Central Africa. Not all individuals can be safely identified. Listen for White-bearded Greenbul’s distinctive calls as it forages on large branches and trunks, and look for its duller red tail and, at close range, its thinner, smaller bill and more slender build. A vocal species, frequently giving “hut-TYER-CHUR!” or similar short, gruff calls.

Tawny-bellied Hermit
Phaethornis syrmatophorus
Large forest hummingbird with long decurved bill and long tail. Rich buffy belly and rump, obvious pale eyebrow and mustache stripe. Elongated central tail feathers with white tips, like many other large hermits. Found in subtropical forest understory in the Andes from Colombia to northern Peru, usually from 1,500–2,300 m. Higher elevation than other hermits. Usually flies by quickly in the dark forest understory uttering a piercing “tseet!” call, occasionally stopping to feed at flowers, especially Heliconia. Rarely visits feeders.
Olive-spotted Hummingbird
Talaphorus chlorocercus
Medium-sized, drab-greenish hummingbird. Dull green above, with diffuse olive spotting underneath, and a white belly. Sexes similar. Found in riverside habitats, especially in cane and other dense vegetation on river islands.
Black-throated Blue Warbler
Setophaga caerulescens
Striking warbler with vastly different male and female plumages. Males are unique deep blue above with black face and sides and white belly. Females are plain brownish-olive with dingy buffy underparts and subtle face pattern. Always look for small white patch on the wing, lacking only on the dullest immature females. Breeds in the understory of mixed forests, favoring hills with dense vegetation. Found in nearly any wooded or shrubby habitat during migration. Winters primarily in the Caribbean. Listen for lazy buzzy song, usually a series of notes with a final long buzz.
