Baya Weaver
Ploceus philippinus
A widespread weaver that is known for its nest—a long hanging nest with a bulbous chamber and a narrow tubular entrance. Breeding males have yellow forehead and crown, a dark throat that contrasts with yellow underparts. Nonbreeding males and females are similar except they have buffy colors where breeding males are yellow; also note the dark streaks on the back and the broad buffy eyebrow on females. Juvenile resembles female, but lack the female’s obvious eyebrow. Baya Weavers lack the strongly streaked appearance of Streaked Weavers. Regional variation in plumage exist mainly in the amount of yellow and black in breeding plumage. Occur as flocks, particularly in breeding season. Advertising calls of males are an easy way to detect the species as several males in the flock call together creating a cacophony of a series of rasping chatters followed by a buzzing whistle interspersed with long chatters.
识别特征
These are sparrow-sized (15 cm [5.9 in]) and in their non-breeding plumage, both males and females resemble female house sparrows. They have a stout conical bill and a short square tail. Non-breeding males and females look very similar: dark brown streaked fulvous buff above, plain (unstreaked) whitish fulvous below, eyebrow long and buff coloured, bill is horn coloured and no mask. Breeding males have a bright yellow crown, dark brown mask, blackish brown bill, upper parts are dark brown streaked with yellow, with a yellow breast and cream buff below.
分类信息
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the baya weaver in his Ornithologie based on a specimen that he believed had been collected in Philippines. He used the French name Le gros-bec des Philippines and the Latin Coccothraustes Philippensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition, he added 240 species that had been previously described by Brisson. One of these was the baya weaver. Linnaeus included a brief description, coined the binomial name Loxia philippina and cited Brisson's work. It was subsequently realised that Brisson was mistaken in believing that his specimen came from the Philippines and the type locality was redesignated as Sri Lanka. This species is now placed in the genus Ploceus that was introduced by the French naturalist Georges Cuvier in 1816.<p>There are five subspecies:

Bar-tailed Trogon
Apaloderma vittatum
Typically beautiful green-and-red trogon. The bottom of the tail is heavily barred black-and-white, and this pattern can also be seen along the edges of the top of the tail. Found in moist montane forest. Usually seen singly or in pairs. Quiet and inconspicuous bird of the mid-story. Usually detected by song: a series of 6-15 downslurred “teew” notes, which becomes louder as the series progresses. Separated from other African trogons by the barred tail.
Village Indigobird
Vidua chalybeata
Nest parasite that lays its eggs in the nests of Red-billed and Brown firefinches. Breeding males are glossy black, while females and non-breeding males are streaky and brown on the back and pale below, with a bold facial pattern. The color of the bill is red in southeast Africa and whitish in western, northern, and central Africa. Found in savanna, scrub, farmland, and towns. Mimics the vocalizations of its host firefinches: low rattling series and high-pitched whistled notes. In southeast Africa, can be separated from other indigobirds by its red bill. Very similar to other indigobirds elsewhere on the continent. Breeding males can be separated by their all-black wings that lack a pale brownish panel. The mimicked vocalizations of its host species can also help confirm identification. In non-breeding plumage, similar to non-breeding Pin-tailed Whydah but separated by red legs.
Common Eider
Somateria mollissima
Flocks of these large sea ducks enliven northern coastlines. Males are white and black with a soft suffusion of green on the nape. Immature males are variable and messy-looking with patches of black and white. Females vary from rich rufous-brown to cold grayish, always with extensive black barring covering body and wings. Slight variation in bill shape and color across subspecies, especially obvious on males; Pacific birds have brightest orange bills, most others have greenish bills. Dives to feed on mollusks and other crustaceans. In late summer, look for flocks of females with dozens of ducklings; broods often join together. Compare females with other eider species, and note details of bill and head shape.
