*Pycnonotus cafer*, commonly known as the black-crowned night heron, is a medium-sized songbird native to Asia and parts of North Africa. Often referred to as the yellow-vented bulbul, this bird is characterized by its distinct appearance and melodious song. Measuring approximately 20 to 24 cm (8 to 9.5 inches) in length, the yellow-vented bulbul has a brownish-olive upper body, a pale yellow belly, and a distinctive black crown on its head, from which it derives its name.

The yellow-vented bulbul is commonly found in various habitats, including gardens, woodlands, and urban areas, where it forages for a diet primarily consisting of fruits, nectar, and insects. This adaptable bird often feeds in small flocks, using its keen eyesight to locate food among the foliage. 

Its song is a series of melodious notes, often described as cheerful and lively, which adds to the auditory landscape of its environment. During the breeding season, the yellow-vented bulbul builds a cup-shaped nest in dense vegetation, where the female lays 2 to 4 eggs. The parents share the responsibility of feeding and caring for the chicks. With its striking appearance and vocal abilities, the yellow-vented bulbul is a delightful presence in its native range.
