The Sooty-headed bulbul (Pycnonotus aurigaster) is a species of songbird in the Bulbul family. Other than Hong Kong, it is also found in most of south-eastern Asia. Its natural habitat is subtropical or tropical moist lowland forests.
In Hong Kong, it is far less common than its cousin the Red-whiskered bulbul (Pycnonotus jocosus).
