Varied Sittella
Daphoenositta chrysoptera
Tiny, short-tailed bird with a thin, slightly upturned bill. Yellow eyering in all plumages, but different subspecies vary tremendously in plumage, ranging from black-headed to white-headed, streaked and unstreaked; in flight all, show prominent pale wingstripe. Inhabits woodlands, where usually seen in small flocks that methodically clamber along tree trunks, probing for insects in bark. Birds give frequent “chip-chip” call as they forage.
Identification
Its crown and head can be white, grey or black, and its body is either whitish or grey often streaked with black and grey. Its wings are black, with a broad bar in either white or cinnamon. The iris is dark orange, and the eye-ring, legs and feet are orange-yellow. The beak is orange with a black tip that can extend as far as the base. Colouration completely depends on the subspecies, and certain subspecies are known to hybridize. In the future, some subspecies may become species in their own right.
Taxonomy
The varied sittella was first described by the English ornithologist John Latham in 1801 under the binomial name Sitta chrysoptera. The generic name Daphoenositta is derived from Greek daphoinos/δαφοινός, 'blood-red, tawny' and sittē, a bird like a woodpecker mentioned by Aristotle. The specific name chrysoptera is from Greek khrusopteros/χρυσό-πτερος, 'golden-winged'. <p>The species inhabits a broad range, and its appearance changes depending on its location, hence the name varied sittella. There are five subspecies:

Behavior
Flocks of the birds forage in trees of all heights, often descending erratically down the trunks in a rather nuthatch-like fashion. Their diet consists of spiders and insects, usually prised from beneath the bark.<p>Calls are a thin, high-pitched chwit becoming the louder, metallic tchweit-tchweit-tchweit of many birds combining in a constant call-and-response as they move towards another tree.<p>In spring and summer (August to October in the north; September to December in the south), larger flocks break up into smaller breeding flocks, typically composed of a breeding pair, along with several unmated adults and immatures from the previous season. The nest is cone-shaped, made of bark, fibres and spider-webs, and placed 5 to 25 m above ground in the fork of a branch or on an exposed limb. A clutch of two or three blue-spotted, white eggs, measuring 17 mm × 13 mm (0.7 in × 0.5 in), is incubated by the female for 18 to 20 days.

Taiwan Fulvetta
Fulvetta formosana
Very small endemic songbird with tiny bill and disproportionately large head. Gray above and below, with rich rufous wings, tail, and lower flanks, white throat stippled in brown, and yellow eye. The throat may appear puffy white (without stippling), depending on the bird's posture. Inhabits shrubbery, brushy areas, and bamboo stands in higher montane forests. Gives simple, high-pitched, two-note calls.
Parasitic Weaver
Anomalospiza imberbis
Odd little short-tailed and chunky-billed member of the indigobird family. The male is yellow, with dark wings and tail, while the female is brown and streaky on the back and buff on the face and underparts. Found in moist grassland and open savanna. Uncommon across its range. Indistinct song consists of short, rasping phrases. Male could be confused with canaries but has an all-black bill. Female resembles female bishops but has a shorter and thicker all-black bill.
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.
