Collared Sparrowhawk
Tachyspiza cirrocephala
Small, delicately-built gray raptor with orange barring on chest and belly. When soaring, tail-tip is notched when not fanned out. When perched, look for a tiny bill, blank-staring expression (no heavy brow), and very skinny legs. Much less likely to circle high in sky than Brown Goshawk, and tends to stick to cover.

The collared sparrowhawk is widespread through mainland Australia, Tasmania and New Guinea and is found in all habitats except the driest deserts. It can occasionally be seen in urban areas and even cities. Although widespread, they are generally uncommon.

Spotted Redshank
Tringa erythropus
Elegant wader with a long fine bill and long reddish legs (dark on breeding adults). Striking breeding plumage dark overall. Nonbreeding plumage is paler and grayer than smaller and chunkier Common Redshank. In flight often appears dark overall with narrow white oval up middle of back. Breeds in arctic bogs and swamps; migrants occur in varied wetland habitats. Usually seen as singles or small groups, though will sometimes congregate in large flocks, especially on wintering grounds. Feeds mainly by wading in fairly deep water, probing and picking with its bill, at times swimming.
Cryptic Warbler
Cryptosylvicola randrianasoloi
Plain, warbler-like tetraka. Uncommon Madagascar endemic that is found very locally in middle- and high-elevation rainforest. Canopy species that sometimes joins mixed flocks. Often sings from an exposed perch. Song is a series of high, thin notes that fades away. Similar to Rand’s Warbler, but eye-stripe is not as bold, and the color of the upperparts is more olive-green than gray. Larger than jeries, with pale legs, a pale lower half of the bill, and no streaks on the throat. Somewhat like Wedge-tailed Tetraka, but inhabits the canopy, is much paler, and lacks a gray ear patch.
Blue Rock-Thrush
Monticola solitarius
Medium-sized thrush-like bird, often seen on mountainsides, sea cliffs, quarries, ruins, and even towns. Males usually unmistakable: western birds are dark blue all over, but may appear all dark at a distance; eastern birds are blue with orange underparts. Females dark brown above, finely barred below. Long bill, wings, and tail make for a distinctive and very different shape than Rufous-tailed Rock-Thrush. Song is melodic and blackbird-like.
