White-rumped Shrike

Eurocephalus ruppelli

A big fluffy shrike with unusual white and dark brown coloration. Note the white crown and the white rump patch that is conspicuous in floppy flight. Immatures look very different, with a dark crown and white cheek, but usually associate with adults. Found in dry savanna and woodland, usually in small flocks. Perches up conspicuously and swoops to the ground to catch prey. Similar to White-crowned Shrike, but ranges don’t overlap. Loud and unmelodious vocalizations include cawing and scolding notes. 

识别特征

The northern white-crowned shrike is a 19–23-cm long passerine. The adult has a white crown and rump, black eyestripe, brown back and wings and black tail. The throat, breast and belly are white, and the flanks are brown. The sexes are similar, but juveniles have a brown crown, white head sides, and grey breast. The flight is parrot-like.<p>Several subspecies have been described, but there is extensive individual variation in plumage. Although birds in the north of the range are larger than in the south, the difference is clinal and the northern white-crowned shrike may be monotypic.<p>The calls are high-pitched squawks, squeaks and chatters, including kek-kek and chee-chee.

行为

The northern white-crowned shrike is gregarious, occurring in groups of up 12 birds. It hunts from an exposed perch, feeding mainly on large insects, usually taken from the ground. It also will feed from the backs of large mammals, like an oxpecker, and occasionally will eat fruit which has fallen to the ground.<p>The neat thick-walled cup nest is constructed from grass and spider webs in a horizontal tree fork 4–6 metres above the ground. The two to four white or lilac eggs are blotched with grey, purple or brown. It is likely that cooperative breeding occurs, given the gregarious habits of this species and the known cooperative breeding of the closely related southern white-crowned shrike.

Philippine Cockatoo

Philippine Cockatoo

Cacatua haematuropygia

A rare large parrot of forest on Palawan and several other scattered islands. Heavily persecuted. Can roost on small islets or in mangroves and forage in more open areas, including agricultural fields. Mostly white with a pale yellowish cheek, undertail, and underwings and a red patch under the base of the tail. Note the pale bill and the bare white skin around the eye. Hidden crest is usually held flat. Unmistakable if seen well, but a distant bird in flight could be confused with an egret. Voice includes various nasal or rasping squawks.

Jameson's Snipe

Jameson's Snipe

Gallinago jamesoni

Chunky snipe of very high elevations in the Andes. Plumage has a complicated pattern of brown, buff, and black; note extensive barring on underparts and thick, drooping bill. Might be confused with Noble Snipe, but does not have a white belly. Compared to Imperial Snipe, it is smaller and lacks the warm, cinnamon coloration. Jameson’s Snipe inhabits paramo grasslands and stunted forest near tree line. Shy and rarely encountered unless flushed, when it gives a burst of sharp, abrupt “kek” notes.

Flores Jungle Flycatcher

Flores Jungle Flycatcher

Eumyias oscillans

A dark flycatcher of denser montane forest. Dingy brown above with a rufous wash to wings, rump, and tail. Dark gray throat and breast, whitish belly, and a buff base to the undertail. Singles and pairs are inconspicuous in the undergrowth and midstory, often joining mixed-species flocks. Separated from Asian Brown Flycatcher by larger size, entirely dark bill, duller underside, and lack of a white throat. Sings a jumbled, high-pitched warbling: “tiritirtir-tu…”
