The olive-crowned flowerpecker (Dicaeum pectorale) is a small passerine bird in the flowerpecker family, Dicaeidae. It is found in far western New Guinea and on adjacent islands.

Contents

It is a small bird, with males having olive upperparts, greyish-green underparts, a white throat and a scarlet breast patch. Females are similar to males, but lack the scarlet breast patch. It is mainly frugivorous, also supplementally feeding on spiders.

Taxonomy and systematics

The olive-crowned flowerpecker is one of 41 species in the genus Dicaeum. It is sometimes considered to be conspecific with the red-capped flowerpecker, Louisiade flowerpecker, or the Halmahera flowerpecker. [2] [3]

The olive-crowned flowerpecker was first described by Saloman Müller in 1843. The generic name Dicaeum is from the Greek δικαιον (dikaion), most likely referring to the scarab beetle, while the specific epithet pectorale is from the Latin pectoralis (of the breast). [4]

Subspecies

There are two recognised subspecies of the olive-crowned flowerpecker: [5]

Description

The olive-crowned flowerpecker is a small bird, 9 cm (3.5 in) in length and weighing 7–7.8 g (0.25–0.28 oz). Nominate males have olive green upperparts and crown, yellowish rumps, grey-green underparts, yellowish-white central abdomen and undertail coverts, white throats, and a large scarlet patch on breast. Females are similar to males, but lack the scarlet throat patch and have yellower center of abdomen and undertail coverts. Juveniles are similar to females, but have more olive underparts. [3]

Vocalisations include a short, insect-like buzzing note, a single, high upslurred note, and a drawn-out chew, repeated at intervals. [3]

Distribution and habitat

The olive-headed flowerpecker is found throughout lowlands in western New Guinea and on nearby islands. It inhabits forest canopy up to altitudes of 1,500 m (4,900 ft), although it can be found up to altitudes of 2,350 m (7,710 ft). It is common to uncommon throughout its range. [3]

Behaviour and ecology

Diet

Like other flowerpeckers, the olive-headed flowerpecker feed mainly on fruit, especially figs and mistletoe. It also supplements its diet with spiders. Foraging is done in the canopy, either alone or in pairs. [3]

Like other flowerpeckers, this tiny bird feeds on fruits and plays an important role in the dispersal of fruiting plants. Unlike many other species in the genus, this species has marked sexual dimorphism with the male having contrasting upper and lower parts with a distinctive bright orange breast patch. The female is dull coloured.

<span class="mw-page-title-main">Black-sided flowerpecker</span> Species of bird

The black-sided flowerpecker, also known as the Bornean flowerpecker, is a species of bird in the family Dicaeidae. It is endemic to the island of Borneo, where it is found in the mountains, primarily above 1,000 m (3,300 ft) in elevation. The species is sexually dimorphic. The male has glossy blue-black upperparts, with a scarlet throat and breast, a dark grey upper belly, olive flanks, a white lower belly, and a buffy vent and undertail coverts. The female is olive-green above and greyish below, with buffy flanks and a whitish throat. It inhabits a range of forest habitats, including primary and secondary montane forest, kerangas forest, and scrub, and is also occasionally found in gardens. It feeds primarily on small fruits—particularly mistletoe berries—as well as seeds, nectar, and various invertebrates. It builds a nest of moss, camouflaged on the outside with lichens and lined with the pith of tree ferns. The International Union for Conservation of Nature rates it as a species of least concern. Though its numbers have not been quantified, the black-sided flowerpecker is said to be common throughout much of its range, and any declines are not thought to be precipitous. However, destruction of forest for palm plantations may impact it.
