识别特征
This little-known astrapia is a medium-sized bird-of-paradise species, excluding the tail. The males reach up to around 69 cm (27 in) long and weigh up to 205g, including the tail, while the smaller female is around 47 cm (18.5 in) long and weighs slightly less at 200g. The males' head to the breast are black with a velvety-blue iridescence, bordered by a characteristic iridescent, coppery-orange gorget-band; the hindneck is an elongated erectile cape with iridescent blue-green plate-like feathers, tipped pinkish-violet (cape may appear fully violet in some views.); upperparts, including wings, are black with a slight bronze-green sheen, underparts are a deep oily green, with larger, scale-like feathers down the sides a shiny lime-green; the impressively long tail feathers are purplish-black with a bluish sheen. The less-impressive females are mainly a dull brownish black, with slight, narrow pale barring ventrally; the upperparts are a lighter brown compared to the blackish head; and the tail is greatly shorter than the males' and generally similar in color, though drabbier and browner. It takes around 5–6 years to reach full adult plumage, like its congeners.<p>The vocalizations of the Huon astrapia are vaguely known, though its calls are described as a rough "jj jj jj"; However, when adult males take flight, their wings produce a "shek" noise akin to a sprinkler, like other members of the genus. Otherwise, they are generally silent and shy.

White-collared Pigeon
Columba albitorques
A dark pigeon that is endemic to the Abyssinian highlands. There is a white mark on the back of the head, and white patches in the wings that are conspicuous in flight. Found at middle and high elevations. Nests in rocky areas as well as in towns and cities, and feeds mainly in grassland and cultivated areas. Can be similar to the highly variable feral Rock Pigeon, but distinguished by the white mark on the head. Not very vocal, but does sometimes give a low cooing call.
Sudan Golden Sparrow
Passer luteus
An unusual small sparrow of dry country. Males have a yellow head and underparts and a chestnut back. Females are much plainer, sandy brown on the back and pale below with a yellow wash. Found in dry thorn savanna, thorn scrub, and semi-desert. Nests colonially, and usually found in flocks, sometimes large, and sometimes mixed with other bird species. Similar to Arabian Golden Sparrow, but almost does not overlap in range. Male is separated by his chestnut back, and females by being duller and less yellow. The common calls include chirps and chatters.
Tufted Tit-Tyrant
Anairetes parulus
Active little bird found in wide variety of scrubby, brushy, and lightly wooded habitats from lowlands to the high Andes. Often in pairs, hopping in bushes and brush with tail often held cocked; can be difficult to see well as it constantly flits about. Best identified by small size, recurved “devil horn” crest, and staring pale eyes; breast streaking finer and less striking than on Yellow-billed Tit-Tyrant, which has limited range overlap with Tufted Tit-Tyrant.
