Breeding Range Map
The green area shows the predicted habitats for breeding only. The habitats were identified using 1991 satellite imagery, Breeding Bird Atlas (BBA), other datasets and experts throughout the state, as part of the Washington Gap Analysis Project. Habitats used during non-breeding months and migratory rest-stops were not mapped.

There is only one recent nest known for this species, near Monroe in Snohomish county, in western Washington, but most records are from eastern Washington.

No habitat was modeled for this species.

This species was first recorded in western Washington near Anacortes in 1958, to where it had probably spread from south-central British Columbia. Our map is based on a combination of data submitted to the BBA and published records from American Birds during the BBA period. The only recent nest known for Washington was seen in 1990 in Monroe. Least Flycatchers are known to become quiet during the nesting season, which may explain the scarcity of confirmed breeding records in Washington. The high number of possible and probable breeding records during the breeding season suggests that breeding occurs much more often than indicated by the low number of confirmed records. Most birds are known from hardwood riparian stands, although one at Hawk Creek Canyon in Lincoln County was observed throughout its stay in a dry Ponderosa Pine stand, from June 25 - 30, 1991.
