Pycnonotus goiavier, Yellow-vented Bulbul

They are found nPycnonotus goiavier01-400early everywhere except in the deep forest. Originally from the mangroves and coastal scrub, they have adapted to become one of the most common birds in cultivated areas (parks, gardens, plantations).

The success of the Yellow-Vented Bulbul is probably due to their wide ranging diet of both plants and animals.

They are fond of berries and small fruits, especially figs and cinnamon tree fruits. They sip nectar, nibble on young shoots, and snack on insects. They forage in bushes and trees for berries and insects, and may even catch swarming insects on the wing.

They also investigate bark for titbits. Unlike other Bulbuls, they forage on the ground, picking grass seeds and titbits, even from roads and pavements.

Yellow-Vented Bulbuls are solitary and feed alone or in pairs, although fruiting trees may attract a flock of them. But they roost in small communities in dense bushes or trees.

Breeding: Yellow-Vented Bulbuls breed widely in Singapore in February to June. Courtship involves wing and song displays. They raise and lower the crown crest as they sing.

Yellow-Vented Bulbuls build well-camouflaged but flimsy, loose, deep, cup-shaped nests. They use grass, leaves, roots, vine stems, twigs. The nest may be untidy on the outside but are neatly lined with plant fibres. They nest in a wide range of places from low bushes, creepers to high trees. They are so used to humans that they may even nest in ornamental plants in residential gardens and even balconies! 2-5 eggs are laid, variable in colour from white to pinkish, with lots of reddish-brown to lavender spots. Both parents incubate and raise the young.

Migration? Yellow-Vented Bulbuls don’t migrate seasonally, but they appear to be high nomadic, moving from place to place regularly.

Status and threats: Yellow-Vented Bulbuls have adjusted well to humans and are not at risk.
