This warbler of the boreal forest breeds in Alaska and across northern Canada to the east coast and south to Pennsylvania. It migrates along the east coast to winter in South America. It is a regular transient elsewhere east of the Rocky Mountains and in California.

In Oregon it is reported in small numbers almost annually with most records being immatures from Harney County and along the immediate coast.
