Brown Boobook
Ninox scutulata
Brown hawk-like owl with large, unsettling yellow eyes. Note solid brown back, patchily brown-spotted white breast, and pale triangle above the bill. Adaptable, found in a wide range of forested habitats from primary rainforest to orchards and gardens. Most active at night and dusk; often hunts from an exposed perch. Gives a series of rising hoots: “woo-wuh! woo-wuh! woo-wuh!”
识别特征
The brown boobook is a medium-sized owl with a length of 32 cm (13 in). It has a hawk-like shape due to its long tail and lack of a distinct facial disk. The upperparts are dark brown, with a barred tail. The underparts are whitish with reddish-brown streaking, although the subspecies found in the Andaman Islands has dark brown underparts. The eyes are large and yellow. Sexes are similar.<p>This species is very nocturnal but it can often be located by the small birds that mob it while it is roosting in a tree. It feeds mainly on large insects, frogs, lizards, small birds, and mice. The call is a repeated low soft, musical oo-uk ...ooo-uk... which may be heard at dusk and dawn. This owl is quite common in towns and cities like Colombo, Sri Lanka, as well as suburban areas close to buildings.
分类信息
The brown boobook was formally described in 1822 by Stamford Raffles from a specimen collected in Sumatra under the binomial name Strix scutulata. The specific epithet is from Latin scutulatus meaning "diamond-shaped". The brown boobook is now placed with the other boobooks in the genus Ninox that was introduced by the English naturalist Brian Houghton Hodgson in 1837.<p>Nine subspecies are recognised:

分布与栖息地
The brown boobook is a resident breeder in most of tropical south Asia from the Middle East to south China. Its habitat is well-wooded country and forest. It lays three to five eggs in a tree hole.<p>There are two records of the brown boobook in the western hemisphere: an individual photographed on St. Paul Island, Alaska, on August 27, 2007, and a dead owl found on Kiska Island in 2008.

Southern Penduline-Tit
Anthoscopus minutus
A tiny, short-tailed bird with a small fine bill, yellowish underparts, a green back, and a gray head with fine grizzled black-and-white scaly patterning on the forehead. Pairs and small groups forage restlessly for invertebrates and fruits, dangling upside down while they search. The species occurs in desert and semi-desert scrub, preferring taller thorn trees for nesting. It is often detected by its song, a repeated series of 5-7 high-pitched “chiueew” notes. Multiple birds may also give simple high-pitched tinkling and rasping notes. The similar African Penduline-Tit differs from Southern Penduline-Tit in areas of overlap by being smaller, lacking a grizzled forehead, and having buff (not yellowish) underparts.
Pohnpei Lorikeet
Trichoglossus rubiginosus
Beautiful dark maroon parrot with a bright orange bill and yellowish tail. Found solely on the island of Pohnpei in the eastern Caroline Islands, where it is the only naturally-occurring parrot. Found in forested areas, both pristine and near human habitation and cultivation. Chatters shrilly and harshly; also gives a high slurred whistle.
Yellow-breasted Racquet-tail
Prioniturus flavicans
A large green parrot with a thin pair of tail rackets, confined to North Sulawesi and satellite islands. Entirely green, except for distinct yellow wash on breast and collar. Males show a small red crown patch. Juveniles lack rackets. Found in pairs and groups in canopy of forests and edges in lowlands and foothills. Prominent yellow breast and large size of this species distinguish it from Golden-mantled Racquet-tail. If rackets are not seen, note the silvery-gray bill, unlike Blue-naped Parrot. Noisy, giving varied vocalizations. Song is a high-pitched “kut-ut-ut-kler-kler.” Also gives screeches, squeaking, piping, and ear-splitting “kraa” notes.
