    Special needs

    Olive-sided Flycatchers are generally associated with open forests, often near water and with tall, prominent trees and/or snags. They may use open, mature coniferous forest, forested riparian areas, forest openings (e.g., burns, harvested forest), and forest edges. They prefer hemlocks or true firs for nesting and require abundant insects for prey.

    Limiting factors

    Olive-sided Flycatchers have relatively large area requirements (compared to other songbirds). They may experience increased predation rates in harvest units within a landscape of mature or highly-fragmented forests.

    Conservation actions

    Maintain scattered, large, dead trees in patchy wildfire zones. Maintain natural openings, but minimize harvested forest openings within mature forest landscapes.
