Pacific-slope Flycatchers and Cordilleran Flycatchers are nearly identical sister species — only voice and DNA distinguish them.
Their position-defining ascending 'pweet' call is one of the most common sounds of Pacific Coast forests in summer.
They construct moss-rich cup nests in shaded crotches and on artificial ledges, often returning to the same spot for years.
If you live in the shade of West Coast conifer or oak forest, a covered ledge near water can host a pair.
Mount the open shelf 6–12 ft up in deep shade — under porch eaves, against a shaded wall, or under a pergola in a forested yard.
A garden stream, pond, or fountain is a strong draw. They're never far from moist habitat.
Aerial insects only — no feeders.
Tall conifers and shaded canopy nearby; they avoid sun-exposed yards.
Don't bother in suburban areas without forest within 100 yards; they need adjacent forest cover.
The coastal sister of the Cordilleran Flycatcher, breeding from southern Alaska down through the Pacific states.
Common breeder in coastal forests from southeast Alaska through BC, Washington, Oregon, and California.
Winters along the Pacific slope of Mexico south to Oaxaca.
Shaded coastal forest — Douglas-fir, redwood, mixed evergreen — and riparian corridors. They favor cool, moist, low-light microhabitats.
No entrance hole, no front wall — just a sheltered ledge. Includes drainage and the integrated mounting tab.
