Golden Greenbul
Calyptocichla serinus
A golden-green bird of forest and forest edge, often seen high above the ground in fruiting trees with other species. Mostly uniform golden-yellow below and yellow-green above with a distinctive pale pinkish bill that is often darkest towards the tip. Gives a drawn out, descending “TSCHEEeeeeew!”, often preceded by a sharp “chup!”
识别特征
The golden greenbul is brightly coloured for a greenbul due to its bright yellow belly and white throat; otherwise it is not particularly distinct in plumage, with unmarked olive upperparts, tail and wings. It has a long slender pinkish-brown bill, a feature not shared by other greenbuls.
分类信息
The golden greenbul was originally described in the genus Criniger. It is not closely related to any of the other greenbul species, forming a separate clade from the two main clades which make up the bulbul family Pycnonotidae. Alternate names for the golden greenbul include the serene bulbul and serene greenbul.

White-spectacled Warbler
Phylloscopus intermedius
Medium-sized warbler with prominent pale “spectacles.” Extent of gray crown coloration is geographically variable; Himalayan birds average the darkest and Chinese birds the palest. Himalayan and Vietnamese birds’ dark gray crowns may recall Gray-cheeked Warbler, but both forms of White-spectacled Warbler have a much more contrasting crown pattern and bright yellow throats. White-spectacled’s eye-ring is broken at the top instead of at the back as it is in Golden-spectacled and Gray-crowned Warblers. Forages at lower levels of the forest, often making sallies after mobile prey. Breeds at medium altitudes in broadleaf hill and montane forest, with Chinese and Himalayan birds moving to lower altitudes in the non-breeding season. Song is distinctly broken and hesitant, slowly picking up as it progresses and ending with a variable trill; contains more trilling than Gray-cheeked Warbler’s song. Lower in pitch and more faltering, less accelerating, than the songs of Gray-crowned and Martens’s Warblers. Presence of any trilling components at all distinguishes this species from Bianchi’s Warbler.
Pale-vented Bush-hen
Amaurornis moluccana
Very secretive medium-sized rail that inhabits dense vegetation around wetland habitats in northern and northeastern Australia. Rarely seen away from cover. Dull gray-blue body, brown wings and tail, with reddish-brown undertail, yellow-green bill with small shield, and long yellow legs. Gives a variety of calls, usually a loud, repeated, squawky "wark-wark-wark" or an agitated "wark-woop, wark-woop, wark-woop."
Javan Banded-Pitta
Hydrornis guajanus
Beautiful ground-dweller with black mask, clean white throat, and finely barred underparts. Male has an egg-yolk-yellow eyebrow, royal-blue “bib”, and black crown. Female has a dull tan-yellow eyebrow and brown crown. Both sexes have a bright blue tail and a white “racing stripe” down the edge of the wing. Inhabits a range of wooded habitats, from primary wet forest to overgrown plantations and dry scrub, in the lowlands and foothills of Java and Bali. Forages on the ground, either singly or in pairs. Gives a loud, bright “whOW!” and a low rolling trill.
