IUCN Conservation Status: Least Concern
A small drab flycatcher of wet, brushy areas, the Willow Flycatcher is best identified by its voice. Nearly identical to the Alder Flycatcher; the two species were considered the same until the 1970s.
Song a harsh "fitz-bew" or "rrritz-bew," accented on the first syllable. Call note a mellow "whit."
