Shy Heathwren

Hylacola cauta

Small bird of open mallee and heathland in southwestern Australia and southern South Australia. Medium gray-brown above, whitish below, with distinct pale supercilium, red-brown rump, large white spot in the primaries (surrounded by black), dark chest streaking, and long, cocked tail. Forages quietly on the ground. Compare Chestnut-rumped Heathwren, which has a smaller pale wing spot, no black in wing, and paler legs. Despite the name, this species is not particularly shy.

Identification

The birds are cock-tailed with a chestnut rump that darkens towards the tip. Their feathers are white with brown streaking underneath and greyish-brown on the back and crown. They have a white eyebrow, tail tip and patch on the flight feathers, and a black bill. Their eyes are brown to yellowish-brown and legs are slate-brown. Females have slightly duller colouring, and immature birds are duller again with some of these being fawn-coloured underneath. They have a total length when adults of 12–14 cm (4.7–5.5 in).

Taxonomy

Their taxonomic name was formerly Calamanthus cautus—classing them as fieldwrens—until they were renamed in 2008. The generic name Hylacola derives from the Greek hylē 'woodland' and the Latin -cola 'dweller'. The specific epithet derives from the Latin cautus 'shy, wary'. Common names for the species include shy hylacola and mallee heathwren. Four subspecies have been recognised: the nominate subspecies Hylacola cauta cauta in South Australia and Victoria; H. c. macrorhynchus in New South Wales; H. c. halmaturina on Kangaroo Island; and H. c. whitlocki in Western Australia.

Blue-faced Parrotfinch

Blue-faced Parrotfinch

Erythrura trichroa

Colorful small finch, usually found in grassy forest clearings or forest edge habitats, often in close association with bamboo. Favors foothills and montane areas throughout much of its range, but descends into coastal lowlands on small islands and in the far eastern end of its range, on Australia’s Cape York Peninsula. Bright green plumage, with an obvious blue face and red tail and rump. Juveniles lack the blue face and are slightly duskier below. Forages at all levels of forest, from the ground up into the canopy, often taking seeds from grasses and bamboo. Call very thin and high-pitched.

Slender-billed Tyrannulet

Slender-billed Tyrannulet

Inezia tenuirostris

Very active, a small, greenish-brown flycatcher with yellowish underparts. Shows a short bill with orange base, faint whitish eyebrow, and contrasting white wing bars. Sexes similar. Common, often alone or in pairs foraging; territorial, found in dry areas with scrub and small trees or mangrove border. Song is a fast trill “tr’r’r’R’R’R’R’r’r’r’r.” Similar to Southern Beardless-Tyrannulet, which shows more of a crest, less contrasting wing bars, and heavier and more curved bill. Found in northeastern Colombia and northwestern Venezuela.

Ochre-throated Foliage-gleaner

Ochre-throated Foliage-gleaner

Automolus ochrolaemus

Skulking and generally inconspicuous brown bird of humid tropical forest. Found as singles or pairs, clambering in vine tangles or other dense understory, at times in leaf litter on the forest floor; usually difficult to see clearly. Note the rich buffy throat, conspicuous buffy eyebrow and eyering, and rusty tail on an otherwise plain dark brownish bird. Song is a descending series of nasal notes, speeding up and often sputtering at the end. Occurs from central Panama (where approaches the range of Fawn-throated Foliage-gleaner, and best distinguished by voice) throughout much of northern South America, to central Brazil.
