Cave Swiftlet

Chunky, rounded songbird with heavy thick bill. Found across a wide range of habitats across its range: largely mangroves in Australia, but also inhabits freshwater swamps in New Guinea and forests and forest edge on smaller islands. Male has an olive-yellow back, black head, white chin, bright yellow underparts, and thick yellow hindcollar. Female plain gray above, paler gray below, with yellow undertail and in some subspecies a yellow belly. Overlaps very marginally with the very similar Golden Whistler in eastern Queensland, but note mangrove habitat as well as slightly longer bill and darker uppertail; also note significant yellow on underparts in female and different song. Vocalizations include variations on whistled songs, sometimes with a whip-like ending.

Endemic pipit found in open habitats from coastline to alpine shrublands. Scarce in intensively farmed areas. Prominent pale eyebrow with brown streaked upper body, pale underparts and brown streaking on breast. Distinctive 'tzweep' call given year round. Repeated high-pitched 'pip-it' territorial song heard mainly in August-February. Often seen walking rather than hopping, frequently flicking their long tail when they stop, or when perched. Can form loose flocks in autumn and winter. Very similar to introduced Eurasian Skylark. Note lack of large head crest, a more slender body, and distinctive habit of wagging its long tail up and down.

Rich chestnut-brown babbler with a bright white throat and chest. Inhabits dry scrubby areas, often fairly close to human habitation. Like other babblers, fairly social, gathering in small bands; birds often give a fairly high-pitched rolling chatter as they forage together.
