Swamp Greenbul
Thescelocichla leucopleura
A loud, boisterous greenbul that is dark gray-green above and pale below. The back, head, and cheeks are all brownish, but feathers on the head have white centers that give them a distinctly grizzled appearance. The underparts grow plainer and whiter toward the tail, which is long and brown with bright white outer feather tips. Most often found near wet, swampy forest, particularly in areas with Raphia palms. Swamp Greenbul flocks are often located by their cacophonous calls, which consist of a series of notes and cackles that are reminiscent of a recorded human conversation being played too quickly.

Ultramarine Flycatcher
Ficedula superciliaris
Incandescently beautiful male is resplendent in electric blue and snowy white. Female is dull gray-brown with paler underparts. Slight regional variation: “Western” males have a short white eyebrow and “Eastern” females have a faint rusty patch on the forehead. Male may be confused with Himalayan Bluetail, but lacks orange. Female is similar to females of Slaty-blue and Little Pied Flycatchers, but lacks any rufous tones on the tail. Breeds in hill and montane broadleaf and pine forests; descends into lower foothills in winter. Rarely heard song a complex series of whistles and chatters; more commonly heard is the call, a dry trilling chatter, sometimes preceded by a short whistle.
Channel-billed Toucan
Ramphastos vitellinus
Large toucan, widespread across South American lowlands. Mostly black with a dark bill (although some populations have a yellow ridge on top of the bill). Significant plumage variation across range: throat color varies from white to orange; bare skin around eye varies from blue to red. In the western part of its range, appearance is very similar to White-throated Toucan, but note voice: a grating croak, not a clear yelp. Singles, pairs, or small flocks are found in the forest canopy, often around fruiting trees. Named for the groove along the upper part of the bill, which is difficult to see in the field.
Gray Teal
Anas gracilis
Plain grayish mottled duck with a rounded crown. Note plain face lacking the bold stripes of Pacific Black Duck. White wing panels are distinctive in flight compared to purple/green of Pacific Black Duck. Told from female Chestnut Teal by the much paler neck/throat. One of the most common ducks in many waterways, forming enormous flocks numbering in the 1000s.
