RED-BACKED WOODPECKER (Dinopium benghalense psarodes) The commonest of nine woodpeckers, the red-backed is a frequent visitor to gardens in the residential areas of Colombo, but is equally abundant in the more remote jungles and well-wooded districts. Generally its presence is advertised by its loud trilling call. It is then seen hopping up or down the trunk of a nearby tree or palm. Usually it starts at the bottom and hops its way up, examining the trunk for ants, beetles, and other insects. Then, having finished one tree it flies to the next, with a jerky, undulatory flight, the noise of its rapid wing beats being audible at a distance.
