Beccafiore corona oliva

Identificazione

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.<p>Vocalisations include a short, insect-like buzzing note, a single, high upslurred note, and a drawn-out chew, repeated at intervals.

Tassonomia

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.<p>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).<p>There are two recognised subspecies of the olive-crowned flowerpecker:
