White-browed Gnatcatcher
Polioptila bilineata
Tiny gray-and-white bird with long cocked tail and rather long slender bill. Fairly common in humid tropical forest canopy and edge, from Mexico to northwestern Peru. Often in pairs, traveling with mixed-species flocks. Both sexes have a thick white eyebrow and ‘open’ face, unlike the narrow white eyebrow (and dark lores!) of White-lored Gnatcatcher, which overlaps in parts of Middle America. Male cap is black, female cap gray.
Taxonomy
The white-browed gnatcatcher was formally described in 1850 by the French naturalist Charles Lucien Bonaparte and given the binomial name Sylvia bilineata. Bonaparte specified the locality as Cartagena, a city on the Caribbean coast of Colombia. This species was formerly considered as a subspecies of the tropical gnatcatcher (Polioptila plumbea). The white-browed gnatcatcher was split from the tropical gnatcatcher based on morphology and phylogenetic data.<p>Five subspecies are recognised:

Tanimbar Corella
Cacatua goffiniana
Small white parrot with short crest, ring of grayish-blue skin around the eye, and pink patch between the eye and the bill. Yellow-tinged undersides of wings and tail often visible in flight. Endemic to the forests of the Indonesian Tanimbar Islands, where now uncommon and declining. Introduced populations are scattered widely around the world and have become established in suburban areas in Taiwan, Singapore, Puerto Rico, Indonesia's Kai Islands, and Japan.

Dayak Blue Flycatcher
Cyornis montanus
A medium-sized flycatcher with strikingly different male and female plumages. Male is beautifully colored, with deep blue upperparts, mostly orange underparts, and a white belly. Female is much duller, with a grayish head, gray-brown wings, a rufous tail, and rufous underparts. Scarce and local in the understory of hill forest. Song is jumble of melodious warbling and whistling notes. The calls are loud “chek” or “sit” notes, and are often mixed into the song. Similar to Bornean Blue Flycatcher, but darker, especially on the belly (in both sexes) and back (in the male). Also similar to Sunda Blue Flycatcher, but darker overall and shorter-billed. Dayak Blue Flycatcher is further distinguished by the less extensive black chin patch of the male and the rufous rather than blue tail of the female.

Golden-collared Manakin
Manacus vitellinus
A small, plump, and short-tailed manakin with a restricted range in Panama and western Colombia. Males are striking with a bright yellow throat and collar, a black cap, and a black back with greenish rump and belly. Females are entirely olive-green with red legs and dark bill and eye. Hybridizes with White-collared and White-bearded Manakins; hybrid males typically have yellow upper backs. Apparently no range overlap with similar Orange-collared Manakin. Occurs in dense understory of forest, second growth, and edges. Males gather in groups to display for females; otherwise most likely to be found at a fruiting tree or sitting quietly in the lower levels of forest.
