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 Ruff is one of the species.
NatureMapping observations reported by townships throughout the year.
The Ruff is an Old World species that is a casual migrant throughout North America, but it is rare along the coasts. It presents annual sightings in winter in California. Breeding sites have been found in North Alaska and east along the Arctic islands. The Ruff is a rare fall migrant in western Washington, peaking in August-September. Most Audubon sightings along the outer coast have been juveniles; Grays Harbor and especially Ocean Shores; Willapa Bay is the best site. It is casual in fall in the Columbia Basin.Text edited by Gussie Litwer
