Pacific-Slope Flycatcher
Empidonax difficilis
Also known as: Western Flycatcher, Cordilleran Flycatcher
About This Species
This small flycatcher inhabits shaded, moist forest along the US Pacific coast, perching on low branches and sallying out to catch flying insects before returning to the same perch. Listen for its soft, upslurred call and sharp position sense as it works forest edges and streamside vegetation. Spring and summer, during the breeding season, are the best times to see it, when males call frequently from territorial perches in the forest canopy and understory.
Ethical Viewing Guidelines
- Its habit of returning to a favoured perch makes for easy, low-disturbance viewing if watchers stay still rather than following the bird between sallies.
- In the US it is protected under federal migratory bird law, which covers nests and young as well as adults.
- Observing quietly from one spot along a forest trail, rather than moving toward a calling bird, gives the best view of its flycatching behaviour without displacing it.
