The yellow-vented bulbul (Pycnonotus goiavier) is a member of the bulbul family of passerine birds. It is resident breeder in southeast Asia from southern Thailand and Cambodia south to Borneo and the Philippines. It is found in a wide variety of open habitats, but not deep forest. It is one of the most common birds in cultivated areas. They appear to be nomadic, roaming from place to place regularly.
The yellow-vented bulbul builds a well-camouflaged but fragile, loose, deep, cup-shaped nest from grass, leaves, roots, vine stems, and twigs. The nest is untidy on the outside, but it is neatly lined with plant fibers. It may be built in a wide range of places from low bushes to high trees. This is a species adapted to humans and may even nest in gardens. The yellow-vented bulbul lays 2–5 eggs in February to June.
The yellow-vented bulbuls eats berries and small fruits. They also sip nectar, nibble on young shoots, and take some insects.
