Yellow-green Tyrannulet

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.

Attractive, medium-sized crested woodpecker of humid tropical lowlands. Uncommon in evergreen forest and edge ranging into adjacent clearings with taller trees. Forages mainly at middle to upper levels, where often quite inconspicuous. Both sexes bright chestnut-brown overall with blond, shaggy, slightly wobbly crest. Male has big red mustache.

Chunky, stout-billed bird of humid evergreen forest and edge in tropical lowlands. Usually found in pairs, often skulking at low to middle levels in lush vegetation. In typical views, looks simply dark. Note the large size relative to buntings, very stout bill, and broad tail, which can be twitched side to side. Male is deep blue-black overall. Female is rich dark brown overall. Sharp squeaky call often doubled and rather distinctive.
