From May to August each year, this is one of the most characteristic birds of western forests—from near tree line down into broadleaf groves in the lowlands. The only requirements for nesting Western Wood-Pewees seem to be trees and aerial insects. Audubon's climate model forecasts a 74 percent loss of current summer range by 2090, mostly showing contraction, but offering some potential expansion to the north. As climate change disrupts forest health in the wood-pewee’s current range, movement to new areas to the north and east seems possible. There will have to be trees, however, and a robust aerial insect prey base—two uncertainties in the face of a changing climate.
