  • Causes of change since first Atlas: Loss of habitat due to changes in forest management practices and fire suppression (?); decreased abundance of preferred prey such asHymenoptera species (?); increase in nest predation in managed forest stands compared to naturally burned stands (?). Possible reduced overwinter survivorship due to loss of habitat on wintering grounds (?).
  • Management/Monitoring recommendations: Retain snags in appropriate habitat; prevent conversion of coniferous forest to other land uses; maintain or mimic natural forest disturbance patterns that create suitable forest openings.
