The snag’s the limit: Habitat selection modeling for the western purple martin in a managed forest landscape

•Purple martins are uncommon but widely distributed in western Oregon.•Purple martin habitat is the presence of moderately decayed snags in early seral forest.•Snags located >100 m from closed-canopy forest are more often chosen for nest sites.•Previous forest management has reduced the availability of nesting habitat.•Infrequent, but major stand-replacing events are likely the key to habitat creation.
