Red-faced Pytilia

Chunky, medium-sized pigeon that has a green back and gray underparts. Also note the purple shoulders and the whitish bill with a red base. Flight is fast and direct. Sometimes alone, though more often in small groups. The species clambers around clumsily like a parrot but can remain well hidden. Found in the canopy of rainforest, secondary forest, and plantations. Most common at middle elevations. Voice is a quiet but maniacal combination of sputters, whistles, and cackles. Easily identified, as it is the only green pigeon on the island of Sao Tome. 

An active but easily overlooked long-tailed greenbul found in flocks in the understory and along the edges of montane forest. Can be found near ant swarms. Has a relatively long brownish tail, generally olive underparts, olive-green upperparts, a pale throat, and a gray face.  Usually found at higher elevations than other similar greenbuls. Foraging behavior and tendency to move tail and hold it lower than the body are distinctive. Often detected by its harsh chatter, “chuk-chuk-chuk,”  or its bubbling “chuk-CHURR-chrchr” song.

The largest nuthatch in North America, with distinctive white face, black cap, and blue-gray upperparts. Also note rusty lower belly and undertail coverts. Females have a slightly paler crown than males. Fairly common and widespread, usually in mature woodlands with large trees. Creeps along tree trunks and branches, often upside-down. Sometimes joins mixed flocks with other songbirds. Visits feeders. Listen for insistent yammering calls. Some subtle variation across range, mainly in the darkness of the sides and back, width of the black crown, and vocalizations.
