The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.
The Washington Gap Analysis Project could not find any historical research records (i.e., Breeding Bird Atlas, Breeding Bird Survey, Bird Banding and Recovery) for 73 species of birds. The Northern Parula is one of the species.
NatureMapping observations reported by townships throughout the year.
This tiny warbler is a rare vagrant throughout the west during migration. It is found in winter far south in Florida and along the east coasts of Mexico. It nests from central to northeast Canada, along the eastern states of the US.Text edited by Gussie Litwer
