Light-vented Bulbul
Pycnonotus sinensis
Common songbird of gardens, parks, and forests. Adult dark olive above, white below, with black-and-white head pattern. Hainan subspecies has a blackish head with white limited to ear patch. Juvenile dull brown above (greenish in wings), white below, lacking head pattern. Hybrids with Styan’s Bulbul appear intermediate, with the moustachial stripe and white feathers around the eye of Styan’s but at least partly white nape of Light-vented. Common song is a ringing series of four notes, “wee-wee-der-wee.”

分类信息
The light-vented bulbul was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with the flycatchers in the genus Muscicapa and coined the binomial name Muscicapa sinensis. The specific epithet is Modern Latin for "Chinese". Gmelin based his entry on "Le gobe-mouches verdâtre de la Chine" that had been described in 1782 by the French naturalist Pierre Sonnerat. The type location has been restricted to Guangzhou (Canton). The light-vented bulbul is now one of 32 species placed in the genus Pycnonotus that was introduced in 1836 by the German zoologist Friedrich Boie.<p>Four subspecies are recognized:

分布与栖息地
It is found in:<p>In Hong Kong, the light-vented bulbul is abundant in lightly wooded areas, cultivated land and shrubland, whereas the red-whiskered bulbul is the common bulbul of suburbs and urban parks.[1]<p>In Taiwan, however, the light-vented bulbul dominates all of these habitats, though it is replaced along the east coast by Styan's bulbul. Chinese bulbuls are seen frequently in Shanghai, where it is perhaps the third most common bird after tree sparrows and spotted doves.[8]

Red-necked Nightjar
Caprimulgus ruficollis
Resembles Eurasian Nightjar, but larger with a rufous collar and upper breast and lacks the dark “forearms” seen on Eurasian Nightjar. Note the prominent pale tips on the wing coverts. Most active at dusk when hawks for flying insects. Voice is a distinctive repetitive “tuok-tuok-tuok” rising and falling in volume. Haunts sparsely to moderately vegetated open areas such as rocky hillsides, pinewoods, and semidesert in the breeding season and winters in similar habitats in West Africa.
African Darter
Anhinga rufa
A long and slender cormorant-like waterbird that often swims with its body submerged and only the “S”-shaped neck protruding from the water. Adults are mostly black with white flecks and streaks. Males have a rusty neck and a white stripe running from the eye down the side of the head, which is duller when not breeding. Females and juveniles are muted and brown. African Darter is widespread in freshwater wetlands, preferring placid to fast flowing waters. Cormorants have proportionately larger heads, bulkier necks, and hooked rather than bayonet-shaped bills.
Tasmanian Boobook
Ninox leucopsis
Small brownish owl with dark ‘glasses’ surrounding eyes. Fairly common in a wide variety of habitats on Tasmania. Similar to Southern Boobook, and range overlaps in southern Victoria during the winter; Tasmanian Boobook is smaller, darker, and has more extensive spotting and a different voice. Call is a familiar ‘boo-book’ with the second note lower pitched than the first, higher-pitched and smoother than Southern Boobook.
