Summary
[edit]DescriptionBEAUTY of RED - VENTED BULBUL.jpg |
English: Scientific name: Pycnonotus cafer
Higher classification: Pycnonotus Rank: Species Did you know: Red-vented bulbuls feed on fruits, petals of flowers, nectar, insects and occasionally geckos. IDENTIFICATION Red-vented bulbuls are slim, starling-sized songbirds with predominantly dark plumage. They are typically bold and conspicuous, with repetitive, monotonous calls. Their slim build and curved bill are reminiscent of a honeyeater (e.g. bellbird or tui), although they are not closely related. The two most distinctive identification features are a small erectile crest on the crown (giving them a square-headed Roman helmet look when the crest is raised) and the diagnostic bright red patch between the base of the legs and the undertail. The head, hindneck and upper breast are glossy black, with a circular brown patch over the ear. This dark hood becomes streaked or scaly on the lower breast and merges into the pale grey belly. The upper wings and mantle are mid-brown with pale margins when in fresh plumage, creating a scaly appearance. The rump is white, and the tail is long and blackish with a prominent white tip. The bill, eyes and legs are dark. The sexes are alike, although males are slightly larger. Juveniles are dull brown with an orange or pinkish (cf. red) vent. Voice: a wide range of calls, from clear whistles to harsh chattering. The usual calls are a 2-3 syllable whistle pee-plo, pee-pee-plo or 'ginger-beer', and a harsh double croak cark-cark. Loud scolding or chattering alarm calls may be directed at predators. BEHAVIOR and ECOLOGY Red-vented bulbuls are active and restless. They have a direct flight with rapid wingbeat, or may undulate over short distances, displaying the bold white rump. They often hawk for insects, with conspicuous fluttering beyond the foliage of shrubs and trees. Once established, red-vented bulbuls form flocks when not breeding. Food Red-vented bulbuls are omnivorous. The main diet is fruit, but insects are also taken, particularly during the breeding season. Flowers and nectar are also consumed, and there are records of small lizards being taken on Pacific islands. In New Zealand they were recorded eating introduced wasps, native bees, cicadas and fruit, including plums and apples. |
