Conservation

Conservation Low ConcernThe American Three-toed Woodpecker populations are difficult to estimate, though they appear to be stable according to the North American Breeding Bird Survey. Partners in Flight estimates a global breeding population of 1.1 million with 21% living in the U.S., and 79% living in Canada. They rate a 10 out of 20 on the Continental Concern Score and are not on the 2014 State of the Birds Watch List. These woodpeckers are sensitive to forest fragmentation, and timber harvest may lead to a decline. The American Three-toed Woodpecker is of concern in several states.Back to top
