Woodpeckers tend to make simple calls, much simpler in structure than those of, for example, most passerines. Calls are highly functional and are made year round, by both sexes. But the extent to which the different species call varies greatly, some are rather taciturn, others (especially gregarious social species) are often noisy. In this photo a Cardinal Woodpecker Dendropicos fuscescens in Tanzania is in full voice (Gerard Gorman).
Here is an often silent, easily over-looked and seldom photographed woodpecker from Africa: Elliot's Woodpecker Dendropicos elliotii male. Photographed in the Bwindi Impenetrable Forest, Uganda, by Gerard Gorman.
