Conservation Concern: 5PIF, WL-Y, FW

Population Trend: Decreasing?
Credibility: Mod. Poor

The Red-headed Woodpecker is an uncommon breeder in the CW Region, common to the south.  This cavity nester typically breeds in dead trees near marshes or in mature oak woodlands.  Although data is somewhat limited, long-term BCN Census trends show a considerable annual decrease of 6%.  Habitat loss, competition with European Starlings, an increase in managed remove of dead trees, and tree loss during controlled burns of marshes and woodlands are all possible contributing factors to this species alarming declines in the CW Region, but more research is urgently needed.
