White-bellied woodpecker

Binomial name: Dryocopus javensis, Thomas Horsfield, 1821

The white-bellied woodpecker or great black woodpecker (Dryocopus javensis) is found in evergreen forests of tropical Asia, including the Indian subcontinent and Southeast Asia. It has 14 subspecies, part of a complex including the Andaman woodpecker (Dryocopus hodgei) (earlier treated as a subspecies). Many island forms are endangered, some are extinct. Populations differ in the distribution and extent of white. They are among the largest of the Asiatic woodpeckers and nest in large dead trees, often beside rivers. Their drums and calls are louder than those of the smaller woodpeckers.

Description

This species is one of the largest living species of woodpecker. Adults range in size from 40 to 48 cm and are second in size only to the great slaty woodpecker among Asian woodpecker species. The species is considered closely related to the more northern black woodpecker and the North American pileated woodpecker and is similar in size to these species. Body mass can vary from 197 to 350 g. Among standard measurements, the wing chord is 20.5 to 25.2 cm, the tail is 14.3 to 18.9 cm, the bill is 4.6 to 6 cm and the tarsus is 3.2 to 4.3 cm.

Subspecies hodgsonii has whitish underwing coverts and a white rump. The face lacks white but juveniles of the nominate race can have white streaks on the throat. Differences from the other Southeast Asian subspecies in the vocalizations and morphology of this species are suggested to be large enough to raise this to full species status. Solitary adults may spend an hour foraging at a suitable tree. Subspecies hodgsonii of India breeds from January to May, mainly in large dead trees, often using the same tree year after year. The normal clutch is usually of two eggs. They feed mainly on insects such as ants or grubs obtained mainly from under bark but sometimes take fruit. Although shy, they can nest close to well used tracks and human disturbed areas. They have a range of calls from a short, sharp "kuk" to more intoned "kyuk", "kew", "kee-yow" calls. The longer calls are given prior to flying off. They roost within holes.

Behaviour and ecology

This large black woodpecker is usually seen singly or as a pair that may sometimes be accompanied by a third bird. They have a dipping in which the loud single note laugh like chiank call is produced. They also produce loud drumming especially in the breeding season. The breeding season is mainly January to March. The nest is built in a large dead tree often in open forest. Two white eggs are the usual clutch. In Bastar in central India, the squabs are sought after by tribals leading to the rarity of these birds.
