Rufous-crowned Emuwren
Stipiturus ruficeps
Tiny buff-brown bird with enormously long, fine tail, found in arid parts of inland Australia. Crown a clean, rich brown, with streaked back, wings, and cheek; underparts buffy brown. Males have a sky-blue throat and upper breast. Tail is much longer and far more spindly than tail of fairywrens. The trick to finding this shy species is to find large unburned patches of spinifex, listening carefully for the species’ very thin, faint calls.
识别特征
The rufous-crowned emu-wren is the smallest and most brightly coloured of the three emu-wren species.The adult male has reddish upperparts with faint streaks, with a prominently rufous crown and grey-brown wings. It has a bright sky blue throat, upper chest, lores and ear coverts. The lores and ear coverts, and chest border are streaked with black. The tail is double the body length, and is composed of six filamentous feathers, the central two of which are longer than the lateral ones. The underparts are buff. The bill, feet and eyes are brown. The female resembles the male but lacks much of the blue plumage and redder crown. Its throat is a yellow buff, and it has some blue-tinged streaked ear coverts. Its bill is pale brown.
分类信息
The rufous-crowned emu-wren is one of three species of the genus Stipiturus, commonly known as emu-wrens, found across southern and central Australia. It was first described in 1899 by Archibald James Campbell, more than a century after its relative the southern emu-wren. Its species name is derived from the Latin words rufus "red" and caput "head". No subspecies are recognised, although birds from Western Australia may have redder plumage, and females more blue on the face and lores. It has been considered a subspecies of both the southern and mallee emu-wrens in the past. The common name of the genus is derived from the resemblance of their tails to the feathers of an emu.

分布与栖息地
The rufous-crowned emu-wren is found across the arid interior of northern central Australia, from the Simpson Desert in the southeast and Barkly Tableland in the northeast, across the centre to the Western Australian coast and the Pilbara in the northwest. There is also an isolated population found to the east in south-western Queensland bounded by Dajarra, Winton, Fermoy and Boulia. It lives in spinifex shrubland.

Sabine's Puffback
Dryoscopus sabini
A relatively large-billed shrike-like bird primarily found in lowland forest canopy. Male is white below and iridescent black above except for a white rump. The female is overall reddish brown, with more reddish wings and a grayish hood. Similar to several bicolored shrikelike birds in the region, but note Sabine’s Puffback’s large bill, striking sexual dimorphism, and unique song, which consists of a distinctive series of long whistles descending in pitch before arriving at a single repeated pitch, growing louder, and then ending suddenly. Songs can sometimes last several minutes, and are more reminiscent of some Yellow Longbill songs than of the songs of other puffbacks. Calls include typical puffback-like rattles and harsh calls.
Purple-throated Woodstar
Philodice mitchellii
Woodstars are tiny hummingbirds that fly like bumblebees. Purple-throated is restricted to the west slope of the Andes in Colombia and Ecuador, where it inhabits cloud forest, edges, and second growth from 800–2,000 m. Males have a glittering purple throat, white chest band, fairly long forked tail, and white patches on the sides of the rump. Unlikely to be confused within range. Females are trickier; note the orangey belly with a variable amount of smudgy white in the center (never as extensive as on female White-bellied Woodstar) and the thin whitish line that extends behind the eye and wraps around the neck (not as wide or buffy as on Little Woodstar). Often seen singly feeding in the canopy; visits feeders.
Velvet-fronted Euphonia
Euphonia concinna
Uncommon within restricted range of the Magdalena Valley of central Colombia, from around 200 to 1,000 m. Occurs in open woodlands. Males are dark steely-blue above and rich yellow below, with a yellow forecrown. Note entirely dark throat and dark underside of tail. Female is dull grayish olive above and yellow below. Note yellow forecrown on female. Could be confused with Orange-bellied Euphonia; male Orange-bellied has white underside of tail and females are grayer below.
