Borneomistelfresser

Bestimmung

The black-sided flowerpecker is a very small passerine, measuring a mere 8 cm (3.1 in) in length. Its weight has not been recorded. Like many flowerpeckers, it is sexually dimorphic; the male is considerably more colourful than the female. The male has glossy blue-black upperparts. His face and the sides of his neck are black, his chin is white, and he has a scarlet throat and breast surrounded by a greyish-black border. His upper flanks and upper belly are dark grey, while his lower flanks are olive, and his lower belly white. His vent and undertail coverts are buffy-yellow. His underwing coverts are white, as are his pectoral tufts. The female has olive-green upperparts and greyish underparts, with buffy flanks, a yellowish rump, a whitish throat and white pectoral tufts. Immature birds are like the female, but more olive-grey below. They are finely streaked with dark from their chin to the breast, and males may show some crimson on the breast. Both sexes have dark brown irises, black bills, and feet variously described as brown or dark grey.<p>The black-sided flowerpecker has a number of vocalisations, including a high-pitched zit, a high, weak tseeep, a quick tsit-tsit, a slurred tsweet tsweet, and a loud, steady clicking.<p>The female can be confused with the plain flowerpecker, but is larger and has a whiter throat. Her back is also more olive-toned, as compared to the browner-backed plain flowerpecker. All other similar species are allopatric—not found on Borneo—so not likely to be confused.

Taxonomie

When Richard Bowdler Sharpe first described the black-sided flowerpecker in 1887, using a specimen collected on Borneo's Mount Kinabalu, he named it Dicaeum monticolum. It is closely allied to, and forms a superspecies with, four other species: blood-breasted flowerpecker, mistletoebird, grey-sided flowerpecker, and fire-breasted flowerpecker. At points in the past, it has been considered conspecific with one or more of those other species in a variety of combinations by a variety of authors. The grey-sided flowerpecker, which is endemic to Sulawesi, is its closest relative. There are no subspecies.<p>The genus name Dicaeum is an Ancient Greek word, perhaps for an Indian bird mentioned by Aelianus. The species name monticolum is Latin for "mountain dweller" or "mountaineer". It is also known as the Bornean flowerpecker.

Verbreitung und Lebensraum

The black-sided flowerpecker is endemic to the montane forests of Borneo. It is typically seen above 1,000 m (3,300 ft) and as high as 2,540 m (8,330 ft) in some locations, though it also descends as low as 460 m (1,510 ft) on two of the island's bigger mountains (Kinabalu and Mount Trus Madi). There are far more records from Malaysia's states of Sabah and Sarawak than from Indonesia's Kalimantan provinces. It is found in primary and secondary forest, kerangas forest (heathland), scrub, and gardens.
