Yellow Bishop
Euplectes capensis
Chunky and large-billed bishop. Male shows yellow shoulders and rump in all plumages, but is otherwise the black in breeding plumage and streaky brown in non-breeding plumage. The female is brown and heavily streaked below, without yellow highlights. Found in grassland, open woodland, heathland, and cultivation. Usually in flocks, especially when not breeding. Song consists of simple twitters and sizzling notes. Females could be confused with many other species but usually associate with males, which show distinctive yellow shoulders and rump.
识别特征
The yellow bishop is a stocky 15 centimetres (5.9 in) long bird. The breeding male is black apart from his bright yellow lower back, rump, and shoulder patches, and brown edging to the wing feathers. He has a short crest, thick conical black bill, and a relatively short tail. His bill size varies dramatically between races.<p>In non-breeding plumage, the black plumage is replaced by heavily streaked buffy-brown, and the bill is pale. The yellow shoulders and rump remain, and are a distinction from the female which lacks the contrasting colour patches. The juveniles and females are notoriously difficult to identify in the field, appearing identical to the juveniles and females of several other bishops and widowbirds as well as some seedeaters.<p>In the breeding season they are usually solitary or in pairs, but the non-breeding yellow bishop is gregarious, often forming flocks with other 'mixed euplectes'.<p>They feed on seed, grain and some insects.

In 1760, the French zoologist Mathurin Jacques Brisson included a description of the yellow bishop in his Ornithologie based on a specimen collected from the Cape of Good Hope. He used the French name Le pinçon du Cap de Bonne Espérance and the Latin Fringilla Capitis Bonae Spei. 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 yellow bishop. Linnaeus included a brief description, coined the binomial name Loxia capensis and cited Brisson's work. The specific name capensis denotes the Cape of Good Hope. This species is now placed in the genus Euplectes that was introduced by the English naturalist William John Swainson in 1829 with the southern red bishop as the type species. There are six subspecies.

Cave Swiftlet
Collocalia linchi
Typical “white-bellied” swiftlet, endemic to Java, Sumatra, and smaller adjacent islands. Dark above, with a gray-brown breast and white belly. Note squared-off tail and green gloss on the back (only visible in good lighting). Rapid flight is erratic and bat-like. Can generally be seen over a range of habitats from lowlands up into highlands, but restricted to highlands in Sumatra. Extremely similar in appearance to Plume-toed Swiftlet, which has a bluer gloss (though lighting can make this tricky) and feathered hind toes (typically only visible in the hand). Gives a dry, scraping chittering, particularly at roosts.
Red Bird-of-Paradise
Paradisaea rubra
A large bird of lowland forests on the northwest islands. Both sexes have yellow bill, chest and back of the head. Male has 2 long black tail streamers, chestnut wings and red plumes which he spreads in his display. Face is bottle green in males and black in females. Doesn’t overlap with any other similar birds-of-paradise. Male gives an often repeated, nasal “caw!”.
Pel's Fishing-Owl
Scotopelia peli
A giant, round-headed, ginger-rufous owl covered by dusky bars, spots, and chevrons. Quite shy; day-roosts are well-hidden in huge trees along permanent rivers and forested swamps with sluggish backwaters. The call is a deep, low, horn-like “Ooom”; also produces a series of grunts. Young birds sometimes emit an eerie screeching: “wheeeuuu”. Similar Rufous Fishing-Owl is smaller and brighter; it lacks bars and chevrons on the underparts. Vermiculated Fishing-Owl has a heavily-streaked upper breast and a pale-yellow (not black) beak.
