Black-backed Woodpeckers occur in low densities, and the ephemeral nature of their preferred habitat make true population estimates difficult to obtain. The North American Breeding Bird Survey estimates that populations have been stable, with a possible increase, between 1966 and 2014. Partners in Flight estimates a global breeding population of 800,000 with 11% living in the U.S., and 89% in Canada. They are a U.S.-Canada Stewardship species and rate an 11 out of 20 on the Continental Concern Score. They are not on the 2014 State of the Birds Watch List. Black-backed Woodpecker are considered a species of special concern in some states. Back to top
