Red-whiskered bulbul (Pycnonotus jocosus), or also called Crested bulbul, is a passerine bird in Asia, a member of the bulbul family. It is a resident frugivore found mainly in tropical Asia.
In Hong Kong, it is more common than most of other bulbuls such as the Sooty-headed bulbul (Pycnonotus aurigaster).
