识别特征
The yellow-rumped thornbill is the largest species of thornbill, 9.5–12 cm (3.7–4.7 in) long and weighing 9 g (0.32 oz). It has a short tail and a long slender bill. The species has a distinctive yellow rump, a black forehead with white spots, grey head and neck, a white line above the eye and white throat. The belly is white with light buff below the wings. The wings are grey and the tail is black. The plumage varies somewhat, depending on subspecies.<p>The yellow-rumped thornbill has a distinctive song described as "twittering, musical, sweet, high-pitched". The species is also reported to be an accomplished mimic of other birds, in particular mimicking the alarm calls of the noisy miner.
分类信息
The yellow-rumped thornbill was described as Saxicola chrysorrhoa by the French naturalists Jean René Constant Quoy and Joseph Paul Gaimard in 1830, from a specimen collected in King George Sound. The specific epithet derives from Ancient Greek khrysos 'gold' and orrhos 'rump'. Four subspecies are recognised: the nominate chrysorrhoa of Western Australia, leachi of Tasmania, leighi of eastern Australia, and normantoni of central and northern Australia. Butterbum is a colloquial name used by Australian birdwatchers.<p>A 2017 genetic study using both mitochondrial and nuclear DNA found the yellow-rumped thornbill was an early offshoot within the thornbill genus, its ancestor diverging from that of all other thornbills just over 10 million years ago.

Rufous-faced Crake
Rufirallus xenopterus
Very secretive crake with a relatively long tail and a stout bill. Note the rufous neck and crown that contrast with a black back, the thinly barred black-and-white sides, and the white belly. Inhabits shallow flooded marshes with tussocky or matted grasses. Compare with Red-and-White Crake, which lacks barred wings and has a white (not black) vent, a yellowish (not gray) bill, and gray (not red) legs. Song is a long descending trill.
Little Ground-Tyrant
Syrtidicola fluviatilis
Small tan flycatcher of river beaches; terrestrial, or perches on low shrubs. Tan above, lighter whitish below, with a black tail with white outer tail feathers. Overlaps with the similar and often more common Drab Water Tyrant. Compared to that species, Little Ground-Tyrant has lighter underparts, no facial pattern (unlike the black eye line and pale eyebrow of Drab Water Tyrant) and white outer tail feathers contrasting with black inner tail feathers (as opposed to uniformly brown). They often flush and move in low flight along river banks, exposing their diagnostic tail patterns. Prefers wide, open beaches and mudflats along rivers to steep river banks. Known to wander when not breeding, when it can be found in a variety of open habitats.
Pringle's Puffback
Dryoscopus pringlii
A small bushshrike in which males and females are strikingly different. Males are black and gray on the upperparts, whitish below. Females are gray-brown on the upperparts, pale gray below. Local and generally uncommon in dry savanna and thornscrub. Usually in pairs. Similar to Black-backed and Northern Puffbacks, but noticeably smaller, with a pale base to the bill. The most common vocalization is an explosive, repeated “kweea,” but the species also gives scolding and ratcheting calls.
