Brown-headed Crow
Corvus fuscicapillus
A large bird from localised areas of lowland forest canopy. Black body, brown head and chest, heavy bill and blue eyes. Immense bill is dark in adult males and yellow in adult females and juveniles. Similar to other co-occuring crow species, but Gray Crow has a bare, pink face and Torresian Crow has a thinner bill and is usually found in more open habitats. Typical crowlike cawing given while dipping its tail and lifting its wing tips.
识别特征
The brown-headed crow grows to a total length of about 22 in (56 cm) including a 7 in (18 cm) tail. It has the typical glossy purplish-black plumage of many of the crow genus apart from the head and neck which are a dark brownish-black. The tail has a squared-off end. The massive beak is compressed and has a high arch, being black in males and reddish or yellowish-white with a black tip in females and juveniles. The legs are black and the face is well-feathered. The nasal bristles are distinctly parted and the throat feathers are bristly. The call is a harsh caw, either in brief, two-syllable utterances or as longer, drawn-out sounds.

分布与栖息地
The species is endemic to eastern Indonesia; it has a fragmented range, perhaps because it has some, as yet unknown, specialised habitat requirement. It is present in northern Papua in the lower part of the Mamberamo River Valley and in the Nimbokrang region, near Jayapura. Also on the islands of Waigeo and Gemien in western Papua, and Nimbokrang and the Aru Islands in Maluku province. Its habitat is primarily virgin forest but it also inhabits secondary growth and mangrove areas, but generally avoids open countryside and the coast. Its altitudinal range is up to about 500 m (1,600 ft).

其他鸟类
Green Broadbill
Calyptomena viridis
Luminous green bird with an oddly umbrella-like head shape, found in lowland forests. Male has black wingbars and a dark “comma” behind the eye. Female is paler green and plainer overall, with no dark markings. In Borneo, overlaps with Hose’s and Whitehead’s Broadbills, both of which tend to be found at higher elevations. In Green Broadbill, note the lack of black on females in any plumage, the clear bars on the wings instead of spots, and the overall larger size. Gives soft, bouncy hooting notes, often in series.
Iberian Magpie
Cyanopica cooki
Unmistakable magpie with a black cap, sandy-brown body, white throat, blue wings, and long blue tail. Highly gregarious, gathers in noisy family flocks giving repetitive “krrr-krrr” calls interspersed with rattles. Usually found in open woodlands with grassy clearings, including orchards and olive groves, but prefers oak woodlands.
Golden-throated Barbet
Psilopogon franklinii
Large green barbet with a broad black bandit’s mask, a pale gray face, and a black-and-yellow crown. Yellow-orange throat patch is small and sometimes missed when seen poorly. Like most other barbets, sluggish and difficult to see, usually encountered foraging quietly or sitting still in the canopy. Song is usually a long steady series of loud hiccupping two-syllabled hoots, but these sometimes sound more plaintive and whistled.
