White-winged Widowbird
Euplectes albonotatus
The breeding male is black with a pale blue bill, brightly-colored shoulder epaulets (chestnut in northeast Africa, yellow elsewhere), and diagnostic white wing panels that are most obvious in flight. The distinctive display is a slow butterfly-like flapping. The non-breeding male is buffy and streaky, but retains the shoulder epaulets and wing panel. The female lacks the wing pattern and has a pale unstreaked belly. Pairs and flocks are resident with local movements in open savanna, brushy grassland, swamps, and cultivated areas.
识别特征
The white-winged widowbird is 15 to 19 cm (5.9–7.5 in) in length and about 23 g (0.81 oz) in weight. The male is the only short-tailed widowbird in its region with white on its coverts. The breeding male is distinguished from the yellow-mantled widowbird by its shorter tail, wing color, lack of yellow on its back, and paler bill. Females are pale below.
分类信息
The white-winged widowbird was first described by the American ornithologist John Cassin in 1848. Hybrids with "red bishops", probably northern red bishop (E. franciscanus), have been reported in captivity. Non-captive interbreeding of race eques with nominate appears to occur in southern Tanzania, but they appear to stay segregated in Burundi and western Tanzania. A proposal has been made for race sassii, which is found along the northwestern shore of Lake Tanganyika. Alternate common names include: white-fronted/white-shouldered widowbird, white-winged/white-shouldered whydah, long-tailed black whydah.<p>Three subspecies of the white-winged widowbird are now recognized.

行为
The white-winged widowbird is polygynous, with one male mating with 3–4 females, and lives in flocks. Oval nests, built solely by the male, are located in the branches of trees or shrubs. Nesting takes place from November to May, peaking from December to March. The female will lay a clutch of two to four white eggs, which she will incubate for 12–14 days. Feeding of chicks is done by the female in the nest for 11–14 days, with chick independence coming 22–25 days later. This bird mainly eats grass seeds, nectar, and insects.

Northern Rosella
Platycercus venustus
Pale yellow rosella with black crown contrasting with white cheeks. The only rosella found in Northern Territory and northwestern Western Australia, where it inhabits open forests and woodlands, often near creeks and streams. Primarily pale yellow and black above, with blue wings and tail and red under the tail. Usually observed in pairs or small groups, generally difficult to find. Call is a clear double note (often repeated); also gives chattering, rattling calls.
Taveta Golden-Weaver
Ploceus castaneiceps
Breeding male is rich yellow with darker orange patches on the breast and the rear part of the crown. The female is dark on the back and buffy yellowish below with a pale base to the bill. Both sexes show a dark eye. Breeds in and around reedbeds, but ranges into surrounding savanna and woodland. Very similar to Golden Palm Weaver, but there is no overlap in range. Also similar to Holub’s and African Golden-Weavers, but usually separated by the black eyes. Females can be confusing, but almost always associate with the more distinctive males. The calls include a dry rattling that is combined with typical weaver “radio static” in the song.
South Island Robin
Petroica australis
A small charcoal-colored songbird endemic to New Zealand. Confined to the South and Stewart Islands. Favors native and exotic forest stands. Males have a more distinct separation between dark gray and cream on their chest than females. Juveniles mirror the look of a female but with less to no cream underneath. Can be incredibly confiding and curious about humans. It is possible to bring individuals out into the open by disturbing leaf litter and then sitting quietly. Actively flushes out prey with foot trembling and by flicking its wings and tail. Male song is a loud and simple phrase of notes including “pwee-pwee-pwee.”
