Birds of Pakistan Series Red Vented Bulbul, July 01, 2013 (2013-18)

RED VENTED BULBUL:- The Red Vented Bulbul (Pycnonotus cafer) is a member of the bulbul family of passerines. It is resident breeder across the Subcontinent, including Pakistan, Sri lanka extending east to Burma and parts of Tibet. It has been introduced in many other parts of the world and has established itself in the wild on several Pacific islands including Fiji, Samoa, Tonga, and Hawaii. It has also established itself in parts of Dubai, the United Arab Emirates and New Zealand. It is included in the list of the world's 100 worst invasive alien species.

The Red-vented Bulbul was originally described by Linneaus in 1766. Several populations of this widespread species have been named as subspecies (or races). The nominate race is found in Pakistan and India, also found in Kashmir and Kohat down to the Salt Range along Hamalayas.

The Red-vented Bulbul is easily indentified by its short crest giving the head a squarish appearance. The body is dark brown with scaly pattern while the head is darker or black. The rump is white while the vent is red. The black tail is tipped in white. The Himalayan races have a more prominent crest and are more streaked on the underside.

Sexes are similar in plumage, but young birds are duller than adults. The typical call has been transcribed as ginger beer but a number of sharp single note calls likened as pick are also produced. Their alarm calls are usually respond to and heeded by many other species of bird.

Habitat and distribution

This is a bird of dry scrub, open forest, plains and cultivated lands. In this native range it is rarely found in mature forest. A study based of 54 localities in Pakistan and India concluded that vegetation is the single most important factor that determines the distribution of the species.

Behavior and ecology:- Red-vented bulbuls feed on fruits, petals of flowers, nectar, insects and occasionally geckos. They have also been seen feeding on the leaves of Medicago sativa.

Red-vented bulbuls build their nests in bushes at a height of around 7 to 10 ft. Two or three eggs is a typical clutch. Nests are occasionally built inside houses or in a hole or in mud bank. In one instance, a nest was found on a floating mat of Water hyacinth leaves and nests in tree cavities have also been noted.

They breed from June to September. The eggs are pale-pinkish with spots of darker red more dense at the broad end. They are capable of having multiple clutches in a year. Nests are small flat cups made of small twigs but sometimes making use of metal wires. The eggs hatch after about 14 days. Both parents feed the chicks and on feeding trips wait for the young to excrete, swallowing the faecal produced.

In culture:- In Pakistan these birds were frequently kept as cage pets and for fighting especially in the Carnatic region. They would be held on the finger with a thread attached and when they fought they would seize the red feathers of the opponents.

They are frequently tamed and carry it about the bazaars, tied with a string to the finger or to a little crutched perch, which is often made of precious metals.
