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.

Black-capped Tanager
Stilpnia heinei
Small, active tanager with notably different male and female plumages. Male is steely blue overall with slightly darker wings. Look for sea-green throat and cheek, streaked upper breast, and contrasting black cap and nape. Female is mostly lime green with pale bluish head and breast; she has just a ghosting of the male’s black cap. Usually found in pairs, often following a mixed-species flock in the canopy. An Andean species, found in subtropical forest, edges, and gardens. Visits fruit feeders.

Mrs. Moreau's Warbler
Scepomycter winifredae
An unusual warbler with a restricted range in the central Tanzanian mountains. Mostly gray, darker on the back, with a rich rufous head and breast. Females are duller. A shy and skulking bird of the understory of montane forest. Usually found in pairs. Somewhat similar to African Tailorbird and Chapin’s Apalis, but chunkier, with more extensive rufous on the head and breast. Normally detected by voice: the male sings a well-spaced series of long, pure whistles, sometimes accompanied in a duet by the female, who gives lower whistles in simple patterns.

White-chinned Thistletail
Asthenes fuliginosa
A small bird that is warm brown above and gray below. Completely unstreaked unlike a canastero. Also note indistinct whitish eyering and short gray eyebrow. Namesake “thistle” tail refers to the long, thin, and pointed tail feathers. Occurs in the Andes from Colombia to central Peru from around 2,800 to 3,500 m. Look for singles or pairs skulking in shrubby areas or stunted woodlands near treeline, not often coming out in the open. Compare with Mouse-colored Thistletail, which is duller brown above and shows a less distinct eyebrow.
