Status:

This species is an uncommon passage migrant in Maryland as it migrates between its breeding grounds in the Boreal forest (fir/spruce habitat) and wintering grounds in the Caribbean and Central and South America. Its numbers fluctuate significantly based on outbreaks of the Spruce Budworm (moth larvae). In fall migration, adults are more likely to migrate west of the Appalachians. First-year birds are more common east of the Appalachians and along the coast. So it isn't just our imagination that this species is easier to see in Maryland in fall!

There are 175 records in the project database.
