Black-capped Bulbul
Rubigula melanictera
Medium-sized greenish bird with a bright yellow underside and black head. Occurs in a variety of habitats, wherever there are trees, including forest, open woodlands, and gardens, in the lowlands and foothills. Usually encountered in pairs or small groups. Yellow throat and lack of black in the wing separates this species from Black-hooded Oriole. Unmarked, black head identifies Black-capped Bulbul from Yellow-eared and Yellow-browed Bulbuls. Song is series of warbling whistles, rising at the end, “wet-wet-wet-wer-wer-wer-weer.” Also gives churring calls.
Identification
The black-capped bulbul is virtually crestless and has a yellow throat and brownish eyes. It is yellowish green above and yellow below. The tail is brownish and ends in a white tip. The male has red irides and the female has brown irides. Calls include a broad repertoire of sweet, mellow, minor-key piping whistles and sharper calls. Breeding records are from March to September.
Taxonomy
The black-capped bulbul was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatchers in the genus Muscicapa and coined the binomial name Muscicapa melanictera. The specific epithet combines the Ancient Greek melas meaning "black" with ikteros meaning "jaundice-yellow". Gmelin based his description on the "yellow-breasted fly-catcher" from Sri Lanka that had been described and illustrated in 1776 by the English naturalist Peter Brown.<p>The black-capped bulbul was formerly placed in the genus Pycnonotus. A molecular phylogenetic study of the bulbul family published in 2017 found that Pycnonotus was polyphyletic. In the revision to the generic classification the black-capped bulbul and four other species were moved from Pycnonotus to Rubigula.Until 2008, the black-capped bulbul was considered as conspecific with the black-crested, ruby-throated, flame-throated and Bornean bulbuls. Some authorities have considered the ruby-throated, flame-throated and Bornean bulbuls to be subspecies of the black-capped bulbul.

Other Birds
Hoary-throated Spinetail
Synallaxis kollari
A skulking, mostly rufous bird with a gray crown and a white throat bordered by black. Throat pattern and long, rufous tail are distinctive. Occurs only in understory of gallery forest in savanna regions along tributaries of the Rio Branco in northern Brazil and western Guyana. Usually in pairs, which clamber through low vegetation searching for insects. Almost always first detected by voice: a hard, doubled note, often given in alternation by members of a pair, and occasionally extended into a longer series, especially in response to playback. No similar species are likely to occur in same habitat.
Rusty-fronted Canastero
Asthenes ottonis
Small, long-tailed bird of high-elevation scrub. Light brown, with reddish wings and tail and small reddish patches on the throat and forehead. Prefers dense shrubby areas, including Polylepis woodland, where it forages secretively within bushes. Its small size, lack of strong streaking, and long, reddish tail distinguish it from similar species within its range. Listen for its energetic song, an accelerating series of high, harsh notes.
Black-crowned Palm-Tanager
Phaenicophilus palmarum
A slow-moving and occasionally tail-twitching species of woodland thickets and dense cover; often found in mixed-species flocks. Note its black face and crown that is boldly marked with white spots and contrasts sharply with an entirely white throat. The similar Gray-crowned Palm-Tanager has a gray crown and a gray center to the throat. Vocalizations include a high thin “tseeoo” and “ts” as well as a nasal “byu.”
