Blue-headed Coucal
Centropus monachus
Huge coucal with a hefty bill. The head often looks black, but can show a blue sheen. Found close to water in marshes, swamps, and wet scrub. Fairly skulking, though occasionally seen in the open. Massive size is obvious in flight. The call is a slow, deep version of the typical coucal descending and accelerating series of “boop” notes. Very similar to Coppery-tailed Coucal, but there is virtually no overlap in range, and Blue-headed is smaller, with a blue sheen to the head. Similar coloration to Senegal Coucal, but much larger.
识别特征
The blue-headed coucal is a medium-sized species growing to 45 to 52 cm (18 to 20 in) in length. The sexes are similar, the adult having the head, sides of neck and back black, glossed with blue, the lower back and rump black, the wings predominantly deep chestnut and the tail black, glossed with green or bronze. The underparts are white or pale buff. The eyes are dark red, the beak black and the legs and feet greyish-black. The juvenile is similar to the adult but the black areas are dull rather than glossy; the head is streaked with rufous-buff, the wings are dark chestnut heavily barred with dark brown, and the back and tail are barred with buff. The throat and breast feathers are spotted with black.

Violet Crow
Corvus violaceus
An entirely blackish short-tailed crow. Has a subtle purplish sheen that is visible in only certain lighting conditions. Juveniles lack purple gloss. Inhabits forest, edge, and plantations in the lowlands and foothills. Singles, pairs, or small groups can be found in the canopy. Recently described from Seram, and perhaps also occurs on Ambon and Buru. Unmistakable, being the only crow on these islands. Gives an odd call for a crow: a nasal, trumpeting “errr.” Gives more crow-like sounds too, but higher-pitched than many sounds of the family, including a high-pitched, guttural “kreh-kreh…”.
Chowchilla
Orthonyx spaldingii
Distinctive, sturdy terrestrial bird found in rainforest of northern Queensland. Mostly deep chocolate-brown, with a prominent pale eyering and robust tail with spiky ends. Male has white throat and belly, female an orange throat and white belly. Forages in rainforest leaf litter, usually in pairs or small family groups. Loud whistler-like calls can sound like "chow-chilla" and give the bird its name.
Banded Prinia
Prinia bairdii
Distinctive and unusual prinia with heavily barred underparts. The mountain-dwelling birds in the eastern part of the range show a dark throat, while in the rest of the range, the throat is barred like the rest of the underparts. Note the white wingbars and spotting under the tail. Skulks in the undergrowth of forest, mostly around clearings and edges. Usually in pairs. The song is a series of mettalic “plink” notes.
