Long-billed Crombec

Sylvietta rufescens

A tiny, rotund, virtually tailless warbler with buff-orange underparts, gray-brown upperparts, and a dark eye-stripe that forms a buffy eyebrow. Pairs often join mixed-species flocks actively hopping along branches, occasionally hanging like mini-nuthatches, searching for invertebrates, and occasionally eating plant matter. Occupies broadleaf woodland, savanna, and arid scrub, where it is often detected by its quiet but distinctive faltering “chree-chirrit, chree-chirrit, chree-chirrit” song. The Red-capped Crombec has paler light gray upperparts and lacks the Cape Crombec’s eye-stripe, giving it a more open tawny face.

The long-billed crombec is a small, nearly tailless bird 12 cm long and weighing around 16 g.

The long slightly curved bill is blackish.<p>The sexes are similar, and the juvenile resembles the adult. The call is a variable series of trilled notes including trreee-rriiit trreee-rriiit and a harsh pttt.

行为

The long-billed crombec's nest is a large, hanging bag of grasses, spider webs, and plant fibres, which is attached to the lower limbs of a tree, often an Acacia. The one to three white eggs are incubated for two weeks to hatching, and the chicks are fed by both parents for another two weeks to fledging. This territorial species is monogamous, pairing for life.<p>This bird is usually seen alone, in pairs, or in family groups as it forages methodically from the bottom to the top of bushes and trees for insects and grass seeds. It will join mixed-species feeding flocks.<p>It moves between trees with a bouncy flight.

保护状况

This common species has a large range, with an estimated extent of 4,500,000 km². The population size is believed to be large, and the species is not believed to approach the thresholds for the population decline criterion of the IUCN Red List (i.e. declining more than 30% in ten years or three generations). For these reasons, the species is evaluated as least concern.

Cinnamon Attila

Cinnamon Attila

Attila cinnamomeus

Medium-sized sluggish flycatcher of riverine and disturbed habitats. Key marks are entirely cinnamon plumage and large-headed, plain-faced appearance; bill seems heavy and is entirely black. Sits still, peering about, before sallying to foliage for insects. Inhabits mid-story and understory, often at forest edge. Found in forest along rivers and oxbow lakes, in abandoned plantations, and at savanna edges, usually near water. Similar to Dull-capped Attila but has dark eyes and different voice. Most common calls are various mournful whistles.

Moluccan King-Parrot

Moluccan King-Parrot

Alisterus amboinensis

A brightly colored, slender, long-tailed parrot of forest and clearings from the lowlands to mid-mountains in the northwest. Red head and underparts, long bluish tail, blue back, and green or bluish wings depending on the race. Similar to Papuan King-Parrot with little overlap, but Moluccan lacks the pale green shoulder bar of the male and green head of the female. Somewhat similar to Chattering Lory but Moluccan King-Parrot has a blue rather than red back and a longer tail. Gives clear, high-pitched, upslurred piping and harsh scolding calls.

Gray-headed Canary-Flycatcher

Gray-headed Canary-Flycatcher

Culicicapa ceylonensis

An unmistakable, dainty woodland flycatcher with a slightly peaked head shape. It has a gray head and upper breast with a narrow white eyering. Upperparts are olive-green; breast and belly are bright yellow. An active member of mixed-species foraging flocks, but also seen singly or in pairs. Quite vocal, with a loud, squeaky whistled song delivered throughout the year: “wi-tu-wi-tu-wee!” or “wi-wuh-wuh-wee!!”. Frequently gives a rapid-fire series of high bouncy notes that rises quickly, then trails off. Other calls include sharp “chilup,” “kitwik,” or “chit” notes repeated a few times.
