Yellow-fronted Barbet

A tiny, stubby, plump dark songbird with a bold red throat in males. Female is nondescript, all gray with a clean white throat. Juveniles resemble female but have a pale-based bill and a green-washed breast. Singles and pairs can be found in lowlands and foothills in a variety of habitats, including forest, forest edge, scrub, and gardens. Male can be separated from male Crimson-crowned Flowerpecker by red throat and lack of red crown. Female Gray-sided differs from female Crimson-crowned in absence of red rump. Song is a thin, high-pitched “see-se-sooo.” Also gives a buzzy “tzjit” note.

Rather large, dark, yellow-tailed bird of humid evergreen forest and edge in tropical lowlands. Where present, colonies of large pendulous nests adorn tall trees. Often in flocks, usually in forest canopy at fruiting trees. Male is much larger than female, but sexes look similar, with a dark, rich brown head and body, blackish upperparts, pale yellowish bill, and bold yellow tail sides. Flight much quicker than larger Montezuma Oropendola, with deep, rather swooping wingbeats that produce a rushing sound.

A fairly small bird of lower montane forest. Both sexes look like a typical female whistler. Yellow belly, olive upperparts, gray head and diffuse band across the chest contrasting with very pale gray throat. Told from the usually higher Regent Whistler female by its plain, pale gray throat and from Sclater’s female by its gray head. Song, a short, whistled, medium-pitch phrase, increasing in volume. Also, an accelerating series of rising, identical-pitch notes with an explosive quality.
