分布与栖息地
Where the green oriole specialises in damp, thickly vegetated habitats in the tropical far north, the olive-backed oriole is more versatile, preferring more open woodland environments, and tolerating drier climates (but not desert). While common to very common in the north, olive-backed orioles are less frequently seen in the south, but nevertheless reach as far as south-eastern South Australia. Their range is from the very north of Western Australia across the east and south coasts to Victoria and the corner of South Australia. Most birds breed during the tropical wet season, but some migrate south to breed in the southern summer.

Cinnamon-breasted Warbler
Euryptila subcinnamomea
A furtive dark brown warbler of rocky gorges, dry river valleys, and boulder-strewn outcrops in semi-arid terrain. At close range, the gray throat in combination with the rusty crown, rump, and variable breast band are diagnostic. It actively hops on rocks and low bushes, sometimes vanishing into a pile of boulders or vegetation only to reappear some distance away. It is scarce and unobtrusive unless vocalizing, when it perches prominently to sing a series or repeated phrase of long, often slurred clear whistles, sometimes mixed with dry rattling buzzy notes.
Brown-headed Honeyeater
Melithreptus brevirostris
Small honeyeater with brown cap. Primarily gray-brown with olive back and lighter underparts. Eye patch and band leading from the eye to back of the head are cream-colored. Juveniles have pale blue coloration around the eye and a yellow bill. Take care to separate from juvenile White-naped Honeyeater, which lacks the pale half collar around the side of the neck. The plumage of this species varies geographically. Common in eucalypt forests, where it is usually very vocal and active. Forages in small groups.
Pinnated Bittern
Botaurus pinnatus
Cryptic heron of freshwater marshes in tropical lowlands. Usually in areas with tall grasses or rushes, rarely in open situations. When alarmed, often freezes motionless with neck upstretched. The neck is finely barred horizontally, but the body plumage is vertically streaked (not horizontally barred and banded, as on immature tiger-herons). Compare with immature night-herons, which have streaked, not finely barred necks.
