The Rockwarbler is a small bird restricted to the sandstone formations around the Sydney region of New South Wales. It is a dark brown-grey bird with a cinnamon-tinged face and forehead, a dull white throat speckled black, reddish-brown underparts, and a black tail, which is often flicked sideways. The wings are dark grey-brown. Young birds are similar to adults but duller. The Rockwarbler is found on sandstone and limestone formations. It is usually found around rocky outcrops, in steep rocky gullies and usually near water, including along sea-cliffs in coastal areas. The Rockwarbler mainly eats insects and sometimes seeds. It forages on the ground and in low branches, probing for insects in rock crevices, in caves and under ledges. Rockwarblers live in monogamous pairs in a permanent home-range. The nest site is usually in a sandstone (occasionally limestone or granite) cave, in total or near-darkness and is re-used each year. It will also nest in darkened buildings, under rafters, on verandahs or in house eaves. The nest is a suspended dome-shaped structure made from roots, moss, grass and bark bound together with spider webs, and has a round side entrance that is sometimes hooded. The inner nest chamber is lined with soft materials, including feathers, fur, grasses and plant down. Both parents feed the young, which stay with their parents for some time after fledging. Sometimes parasitised by Fan-tailed Cuckoo.(Source: Birdlife Australia, n.d.), (Image: Dean-Ingwersen).

The Spotted Pardalote is sometimes known as the "Headache Bird" because of the continuous "sleep-may-be" call it gives during the breeding season. It is a tiny bird that is most often high in a eucalypt canopy, so it is more often detected by its characteristic call. The wings, tail and head of the male are black and covered with small, distinct white spots. Males have a pale eyebrow, a yellow throat and a red rump. Females are similar but have less-distinct markings. The Spotted Pardalote is mostly found in eucalypt forests and woodlands but occurs in parks and gardens with well-established eucalypt canopy. The Spotted Pardalote forages on the foliage of trees for insects, especially psyllids, and sugary exudates from leaves and psyllids. Their call is a repeated three-note whistle, the second two notes higher than the first. Their nest is an enlarged, lined chamber at the end of narrow tunnel, excavated in an earth bank. Sometimes they nest in tree hollows and occasionally in artificial structures. Both parents share nest-building, incubation of the eggs and feeding of the young when they hatch.

The Striated Thornbill is a medium-sized thornbill with greenish upperparts, an orange-brown cap, streaked distinctively with white and off-white to cream underparts, heavily streaked on chin, throat and breast. The sexes are similar and young birds are only slightly different to adults, with less streaking on the underside. The Striated Thornbill is found in open forests and woodlands, mainly those dominated by eucalypts, with a well-developed understorey. Sometimes seen in parks and gardens, preferring areas that are more than ten years old. Also common in agricultural areas, particularly in areas with remnant patches or tree corridors near forests or woodlands. The Striated Thornbill feeds mainly on insects, but may sometimes eat seeds, nectar or fruit. They mainly feed in trees in small flocks, but may sometimes feed on the ground. Will be seen feeding in mixed flocks with other small insect-eating birds. Striated Thornbills may be important in reducing psyllid infestations after Bell Miners (which 'farm' the psyllids) have been removed from an area. Striated Thornbills breed in small related groups, defending a particular nesting territory. Both members of a pair of Striated Thornbills help to build the oval, domed nest, with a hooded entrance near the top, out of bark mixed with lichen, mosses and spider webs and egg sacs (the nest is commonly covered with white material), lining it with feathers, fur or soft plant down. The nest is usually in the outer branches of trees, shrubs and vine-covered saplings, mainly of eucalypts. The female incubates the eggs and both parents feed the young, along with other members of the breeding group. Nests may be parasitised by Horsfield's and Shining Bronze-cuckoos, as well as Fan-tailed Cuckoos. (Source: Birdlife Australia, n.d.).
