Calls
Call is a nasal tooting kent often described as the sound of a “tin trumpet” or of blowing on a clarinet mouthpiece. The call could be given singly or as two notes together, and was often given while feeding. The sound was not nearly as loud as a Pileated Woodpecker’s call, and was estimated to be audible from a quarter-mile away at best.
Other Sounds
The Ivory-bill made a very fast double tap with its bill, with the second tap being slightly quieter than the first, and sounding almost like an echo. The closely related Pale-billed Woodpecker of Central America makes a similar double-tap. It did not have a rolling drum like the Pileated and many other woodpeckers.
