Chestnut-crowned Babbler
Pomatostomus ruficeps
Large, conspicuous songbird with long decurved bill, gray mask, whitish eyebrow, chestnut crown, pale wingbars, and dark eye. White throat and breast with black border extends to upper belly; lower belly and undertail dark. Forages mostly on the ground in noisy flocks, in dry open woodlands of southeastern Australia.
Identification
Chestnut-crowned babblers are dark, brown-grey birds with a white throat and breast, white-tipped tail and a long, black, down-curved bill. Wings are short and rounded and the tail is long with a rounded tip. Diagnostic features include two white wing bars and a rich, chestnut crown highlighted by long, white eyebrows. The birds have dark brown eyes and grey legs, while the wings, back and flanks are brown-grey to mottled dusky on the mantle. The white of the throat and breast is well-defined and narrower than that of the similar, white-browed babbler (Pomatostomus superciliosus). Combined, these characteristics give the chestnut-crowned babbler a rather unusual appearance.<p>At 21–23 cm and approximately 50 g in weight, the chestnut-crowned babbler is noticeably smaller than the grey-crowned babbler (Pomatostomus temporalis). It also gives the appearance of being slimmer than other babbler species. Adults are sexually monomorphic. Immature birds are like the adults but duller, with a pale rufous eyebrow and chest, brown crown and whitish patch behind the eye.

Range and habitat
Chestnut-crowned babblers are found in inland areas of south-eastern Australia, including parts of western New South Wales, south-western Queensland, eastern South Australia and north-western Victoria. Its distribution lies within the south-eastern Lake Eyre Basin and the western Murray-Darling Basin.<p>The species commonly inhabits mallee, mulga and belar woodlands that are drier and more open than those occupied by the white-browed babbler and Hall's babbler (Pomatostomus halli). Other habitats include acacia and cypress pine scrubs and woodlands, stony ground and sandhills, and lignum, saltbush and samphire.<p>Chestnut-crowned babblers are most readily sighted at Eulo Bore, Bowra Station and in Hattah-Kulkyne National Park, as well as along many outback roads including those between Quilpie and Windorah, and Bourke and Nyngan.

Behavior
Babblers are renowned for their cheerful, energetic, social behaviour. During the non-breeding season (December - June), chestnut-crowned babblers form cohesive social groups of 3 to 23 individuals that maintain a territory, roost and forage together. Dust-bathing and preening may also be undertaken as a group. At night, they crowd together in a communal roosting nest, built by the group in dead or partly living trees. These dormitory nests may also be disused breeding nests to which the group continues to add material.<p>If disturbed, individuals hop away behind cover, departing in long, low glides. When alarmed, they may huddle together under dense foliage or dash up the under-canopy of trees and shrubs, chattering noisily. They are playful and have been known to wear trenches in the ground from chasing each other around; however, they are shyer than other babbler species.
Conservation
Internationally, the chestnut-crowned babbler is listed as least concern on the IUCN Red List. It is not listed as threatened under Australia's national Environment Protection and Biodiversity Conservation Act 1999 or under Queensland, New South Wales, Victorian or South Australian legislation. Little is known about its movements but the species is thought to be sedentary and it is scarce to locally common.

Andean Pygmy-Owl
Glaucidium jardinii
Very small owl of the upper subtropics and temperate forest. Typical pygmy-owl plumage: mostly brown or rufous above, white below with messy brown stripes, and small whitish spots on crown. Sexes similar. Found at higher elevations than other pygmy-owls, mostly from 2,500–3,500 m. Usually seen in the daytime perched at middle or upper levels of forest, often being mobbed by hummingbirds or small passerines. Typically detected by song, which can be given at any time of day but mainly early and late: a series of whistled toots, sometimes with a few quavering notes at the beginning.
Scrub Greenlet
Hylophilus flavipes
Small vireo-like bird, olive above and yellowish below with a grayer head. Quite nondescript but look for pointy pink bill, and in most populations, a pale eye. Birds on Tobago have dark eyes. Sexes alike. Prefers scrubby second growth, usually low. Often seen in pairs. Listen for simple series of whistled notes.
Orange-crowned Warbler
Leiothlypis celata
Nondescript warbler, generally olive-colored overall, but different populations vary from grayer to brighter yellow. Overall very plain and unmarked, but note short darkish line through eye and thin pale eye arcs. Forages for insects in scrubby areas, woodland edge, and thickets. Namesake orange crown is very difficult to see, and usually only a faint wash at best. More common in western North America, from Alaska to Mexico, where populations are brighter yellow-green. Birds in eastern North America are scarcer and drabber, often with a more contrasting grayish head. Bright yellow undertail coverts help separate Orange-crowned from the similarly drab Tennessee Warbler.
