Double-barred Finch
Stizoptera bichenovii
Small white, gray, and black bird with a white rump and black tail. Adult has a thin black outline around pale face, lending a sort of "Barn Owl" look, as well as a second thin black breast band. Juvenile similar in pattern but dirtier gray. Inhabits open grassy habitats of far northern and eastern Australia, seen typically in pairs or small groups feeding on the ground.
识别特征
The double-barred finch is a 10–11 cm long munia-like bird. It has a white face bordered with black, brown upperparts and throat, and white underparts. The throat and underparts are separated by another black line. The wings are patterned in brown and white. The sexes are similar, but juveniles are duller and browner. The subspecies S. b. annulosa differs from the nominate in having a black rather than a white rump.
分类信息
The double-barred finch was formally described in 1827 by the naturalists Nicholas Vigors and Thomas Horsfield from specimens collected near Shoalwater Bay and Broad Sound in Queensland, Australia. They coined the binomial name Fringilla bichenovii. The species was formerly placed in the genus Taeniopygia. A molecular phylogenetic study of the Estrildidae published in 2020 found that the genus Taeniopygia was not monophyletic. In the reorganization to create monophyletic genera, the double-barred finch was moved to the resurrected genus Stizoptera that had been introduced in 1899 by the American ornithologist Harry C. Oberholser. The genus name combines the Ancient Greek stizō meaning "to tattoo" with pteron meaning "wing". The specific epithet commemorates James Ebenezer Bicheno, a colonial secretary of Van Diemen's Land appointed in September 1842.<p>Two subspecies are recognised:

Relict Gull
Ichthyaetus relictus
This small black-headed gull breeds on scattered saline lakes throughout central and northern Asia, as far east as Mongolia and northeastern China. However, it is seldom seen on its breeding grounds due to their remoteness. It winters in estuaries, beaches, and mudflats, where adults shed their handsome dark hoods for smudgy “earmuffs.” First winter birds are similar, but have light brown speckling on the wings (solid gray in adults, save for black-and-white tips). Stubbier-billed than Black-headed Gull and generally paler-headed than Saunders's Gull.
Red-capped Cardinal
Paroaria gularis
Small, boldly colored tanager found in vegetation around lakes and rivers. Bright red head and black-and-white plumage are instantly recognizable. Quite social and often found in pairs or groups as they forage low in waterside vegetation. Frequently perches on branches sticking out of the water.
Musk Duck
Biziura lobata
Large and chunky stiff-tailed diving duck with a heavy triangular bill. Floats very low in the water. Both sexes are dark grayish, but male has an obvious lobe of skin dangling from its chin. Usually observed on the water, regularly diving while feeding. Bill is much shorter and heavier than Blue-billed Duck.
