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 Semi-palmated Sandpiper is one of the species.
NatureMapping observations reported by townships throughout the year.
This shorebird breeds in the tundra of northern Alaska and the Arctic. It is a common migrant through the center of the North American continent, from Alaska to Mexico. It is a rare migrant in the west, very rare in winter in Florida.Text edited by Gussie Litwer
