It is among the largest of the Asiatic woodpeckers and nests in large dead trees, often beside rivers. It has 14 subspecies, and many of its island forms are endangered, some are extinct. Populations differ in the distribution and extent of white. Its drums and calls are louder than those of the smaller woodpeckers.
