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:

Spix's Guan
Penelope jacquacu
Large, stocky brown bird. Largely arboreal, but often seems too large or clumsy for its tree-dwelling habits. Calls loudly when flushing from a tree and makes crashing noises as it lands roughly in another tree. Found around forest edges and young forest as well as in more mature forests. Typically found singly or in pairs, occasionally in larger groups. Larger and darker than chachalacas with more prominent red skin on throat.
Golden-crowned Kinglet
Regulus satrapa
Tiny, hyperactive songbird usually found in conifer trees. Look for black stripes on the head and bold wing pattern. The namesake golden crown is usually just a small stripe, but can be flared into an expressive fiery-orange crest when agitated. Breeds in coniferous forests, usually staying high in trees. In migration and winter, often joins mixed flocks of other songbirds in a wider variety of wooded habitats. Very active; often hovers and flicks wings as it forages. Listen for extremely high-pitched call notes.
Red-cowled Cardinal
Paroaria dominicana
A conspicuous inhabitant of woodland in the Brazilian caatinga, but it is also found in scrubby areas and urban parks where it forages on the ground in pairs or small groups. Note the red head and throat, mostly gray back, black wings, and black tail that is white below. Immatures have a duller orange head. The song is a series of fast melodic whistles.
