Australian Swiftlet

Aerodramus terraereginae

Small plain grayish swiftlet with a pale rump and a slightly darker cap. Almost always seen in flight; note slender wings, very quick stiff wing beats. Possible confusion with Tree Martin, which is much paler below with a paler rump, plumper body, and shorter wings. Abundant in tropical north Queensland.

Identification

It is 11–12 centimetres (4.3–4.7 in) long with a wing length of 107–118.2 millimetres (4.21–4.65 in) and a weight of 10.5–12.5 grams (0.37–0.44 oz). The upperparts are dark grey-brown while the underparts are a uniform greyish. There are pale feathers on the forehead and lores. The rump is normally pale greyish but can occasionally be darker. The tail is slightly forked. The form chillagoensis is smaller and paler with a weight of around 9.39 grams (0.33 oz).<p>It has a high-pitched flight call. In its breeding caves, it utters a metallic clicking call, used for echolocation.

Range and habitat

A. t. terraereginae occurs in tropical north-east Queensland from the Claudie River on the Cape York Peninsula south as far as the Eungella Range near Mackay. It is mainly found near the coast including a number of offshore islands. It occurs up to 1,000 metres (3,300 ft) above sea-level but is commonest below 500 metres (1,600 ft). A. t. chillagoensis is found further inland in the area around Chillagoe, west of the Great Dividing Range.

Gray-headed Bushshrike

Gray-headed Bushshrike

Malaconotus blanchoti

A large, robust bushshrike with a chunky hook-tipped bill, a bright yellow eye, and a massive gray head with a small pale patch in front of the eye. Singles and pairs inhabit arid thornveld, broadleaf woodland, riverine forest, and thickets, seldom joining flocks. The species forages slowly and deliberately, hopping along branches diligently searching for large insects and small vertebrates. A low-pitched, extended sorrowful “whhooooooo” song is given up to 50 times in succession, along with other harsh clicks and rasps. Other similar large bushshrikes are rainforest specialists and have more pale in front of the eye.

Manus Dwarf-Kingfisher

Manus Dwarf-Kingfisher

Ceyx dispar

A small blue-and-orange kingfisher with a bright waxy orange bill, ginger underparts, a white throat, and blue upperparts with a bright white neck spot. Female has a bright orange, not blue, head with a blue crown. Found in forest habitats, not necessarily near water, tolerating plantations and degraded forest. No other dwarf-kingfisher shares its range. Told from Common Kingfisher by smaller size and entirely red bill. Call apparently nearly identical that of other Melanesian dwarf-kingfishers: a high-pitched, weak repetitive whistle, often given in flight.

Chestnut-collared Swallow

Chestnut-collared Swallow

Petrochelidon rufocollaris

Handsome swallow restricted to relatively dry regions of western Ecuador and western Peru. Plumage is blue and white with chestnut collar, breast band, sides, rump, and forehead. Similar to Cliff Swallow, which is a rare migrant within the range of Chestnut-collared, but note the chestnut breast band and lack of white on the forehead. Most often encountered around cities and towns, where it nests colonially in the eaves of buildings.
