Biak Hooded Pitta

Pitta rosenbergii

Beautiful leaf-green pitta of Biak Island, off northwestern New Guinea. Like the other “Hooded-type” pittas with which it was formerly grouped, this species has a black head, powder-blue shoulder patch, and red on the lower belly and undertail. In addition, this species has a broad deep blue border to the red belly patch, much like the Eastern Hooded Pittas on neighboring Numfor Island. Song is a rather harsh, rolling “weer, weer.”

识别特征

The Biak hooded pitta (Pitta rosenbergii) is a passerine bird in the pitta family Pittidae that is endemic to the island of Biak, northwest of New Guinea. It is a green bird with a black head and chestnut crown. It forages on the ground for insects and their larvae, and also eats berries. It breeds between February and August, the pair being strongly territorial and building their nest on the ground. Incubation and care of the fledglings is done by both parents. It was formerly considered to be a subspecies of the hooded pitta, now renamed to the western hooded pitta.

分类信息

The Biak hooded pitta was formally described in 1871 by the German naturalist Hermann Schlegel from a specimen that had been collected by Hermann von Rosenberg. Schlegel coined the binomial name Pitta rosenbergii where the specific epithet was chosen to honour the collector. The Biak hooded pitta was formerly considered to be a subspecies of the hooded pitta (Pitta sordida) (renamed as the western hooded pitta). It is now considered as a separate species based on the genetic, morphological and vocal differences. The species is monotypic: no subspecies are recognised.

Golden Vireo

Golden Vireo

Vireo hypochryseus

Small, rather chunky but long-tailed bird of tropical forest and woodland in lowlands and foothills; endemic to western Mexico. Feeds at all levels, often at fruiting trees and bushes with other vireos and fruit-eating birds. Like most vireos, generally rather sluggish. Bright yellow-and-greenish plumage, plus cocked tail, strongly suggest smaller and more lightly built Wilson’s Warbler, but note the vireo’s broad pale eyebrow, stouter bill, and stronger blue-gray legs.

Red-legged Partridge

Red-legged Partridge

Alectoris rufa

Distinctive gamebird of farmland, grassy fields, and open heathland. Seen mainly as pairs and small groups, often along the edges of fields. Plumage is ornate and handsome, with a red bill, white throat, black streaked necklace, boldly barred flanks, and buffy belly. Other similar species (such as Chukar) do not overlap in native range, but can escape from collections or be introduced for hunting; all lack the diagnostic black-streaked necklace of Red-legged. Song is a dry, rasping “wa-cha-cha-wa-cha-cha” or “wi’ch-ch’ch.”

African Piculet

African Piculet

Verreauxia africana

A tiny woodpecker of forest and forest edge, more likely to be mistaken for a crombec than for another species of woodpecker. A squat bird with a round body, a large head, a short, stout bill, and a very short tail. Body is gray overall with greenish wings, white markings around the ears, and orange around the eyes. Males have an orange forehead. Voice is a weak trilling “si-si-si-si-si.”
