Bulbuls (Pycnonotidae) are a family of medium-sized passerine songbirds. 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.
The Red-whiskered Bulbuls and Red-vented Bulbuls have been captured for the pet trade in great numbers and, has been widely introduced to tropical and subtropical areas, for example southern Florida, Fiji, Australia and Hawaii. Some species are regarded as crop pests, particularly in orchards.
