The best known call of this very vocal woodpecker is a raspy “sklit” it gives when disturbed. Other calls include a “churt” (repeated every 2-4 seconds) when flying into a roosting and nesting area, and a rattle that ends with a drop in pitch. Foraging birds give a soft, melodious chortling call when close to each other.
Both males and females drum on tree trunks, although not often or loudly. While foraging they may produce a soft drumming sound, similar to the rattle of a rattlesnake, by vibrating their tongues on the tree surface.
