Posted: Sat Mar 15, 2014 8:05 pm
Bulbuls are a family, Pycnonotidae, of medium-sized passerine songbirds. Many forest species are known as greenbuls, brownbuls, leafloves, or bristlebills. The family is distributed across most of Africa and into the Middle East and Asia. There are about 130 species in around 24 genera.
Bulbuls are short-necked slender passerines. The tails are long and the wings short and rounded. In almost all species the bill is slightly elongated and slightly hooked at the end. Overall the sexes are alike, although the females tend to be slightly smaller. The soft plumage of some species is colourful with yellow, red or orange vents, cheeks, throat or supercilia, but most are drab, with uniform olive brown to black plumage. Species with dull coloured eyes often sport contrasting eyerings. Some have very distinct crests. Bulbuls are highly vocal, with the calls of most species being described as nasal or gravelly.
Bulbuls eat a wide range of different foods, ranging from fruit to seeds, nectar, small insects and other arthropods and even small vertebrates. The majority of species are frugivorous and supplement their diet with some insects, whilst there is a significant minority of specialists, particularly in Africa. Open country species in particular are generalists.
The bulbuls are generally monogamous. Up to five purple-pink eggs are laid in an open tree nests and incubated by the female. Incubation usually lasts between 11–14 days, and chicks fledge after 12–16 days.
