The Northern Flicker Woodpecker Call is a loud, clear note that often sounds like a sharp “kyeer,” making it easier to recognize once you know its tone. The bird also produces a rolling, rattling song that can last several seconds, along with a rapid drumming sound when communicating or defending its territory. To confirm the identification, listen for these distinctive sounds and look for a large brown woodpecker with black spots, a white rump, and colorful yellow or red wing and tail undersides, depending on the region.
