Yellow-mantled Widowbird
Euplectes macroura
The long-tailed breeding male is a spectacular and unmistakable black-and-yellow bird. Varies geographically, with some birds showing a completely yellow back, and others only a yellow shoulder. Females and non-breeding males are streaky and brown, though males retain their yellow shoulder. Found in many open habitats, including cultivation, moist grassland, marshes, and forest clearings. The song is a series of harsh “zhet” notes, which the male often gives in a display flight. Female can be confused with several other species, but is usually identified by association with yellow-shouldered males.
识别特征
Males are larger than females and acquire longer tails and striking black and golden yellow plumages in the breeding season. The mantle colour is either golden yellow, or in the case of the northeastern race, E. m. macrocercus, black. The yellow shoulders persist in all male plumages, whether breeding or non-breeding.
分类信息
The yellow-mantled widowbird was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the crossbills in the genus Loxia and coined the binomial name Loxia macroura. Gmelin specified the locality as "Whydah"; this is Ouidah on the coast of Benin is East Africa. The specific epithet is from Ancient Greek makros meaning "long" and -ouros meaning "tailed". The yellow-mantled widowbird is now one of 18 species placed in the genus Euplectes that was introduced in 1829 by the English naturalist William John Swainson.

Rufous-tailed Antbird
Drymophila genei
Medium-sized antbird with a long rusty tail and rusty wings. Found in the understory of dense humid forests with bamboo. Males have a black crested crown and a well-marked face with a black mask and a long white eyebrow. The face, breast, and back are spotted black and white while the rest of the body is rusty. Females differ in having a brownish crown with black streaks and are buffy on the breast, and nape with faint streaks and tawny buff below.
Dusky Robin
Melanodryas vittata
Medium-sized, rather long-tailed Australian robin, both sexes plain brown overall. Darker than similar species and lacking any pale wing panels. Often perches on a rock or stump, from which it pounces on prey on the ground. Endemic to Tasmania, where inhabits open forests, gardens, and coastal heathland.
Mangrove Pitta
Pitta megarhyncha
The huge crab-smashing bill of this mangrove specialist sets it apart from all other pittas. Brightly colored with a black mask, green-and-black wings, and a yellow belly. Similar in color to Blue-winged Pitta, but note Mangrove’s larger-headed appearance and habitat. Like other pittas, shy and difficult to see; listen for its throaty and fluid two-parted whistles.
