This bird's call is a sustained laugh, ki ki ki ki, quite different from that of the pileated woodpecker (Dryocopus pileatus).

[13] In an intraspecific conflict, red-bellied woodpeckers usually make a loud "chee-wuck, chee-wuck, chee-wuck" sound ...
The red-headed woodpecker was historically a common species in southern Canada and the east-central United States. Consistent long-term population declines have resulted in red-headed woodpecker's threatened status in Canada and several states in the US. Throughout most of its range, it inhabits areas that have been heavily altered by humans.
