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.
NatureMapping observations reported by townships throughout the year.
This shearwater is a seabird that is abundant off the west coast and can often be seen from shore. It is also fairly common along the east coast. This shearwater is a common offshore visitor in warmer months, from just beyond the breakers to pelagic waters in Washington. It is rare in winter. It is the most seen shearwater from shore. Immense numbers pass by in August-September. Sometimes thousands enter Grays Harbor and Willipa Bay. It is uncommon in the Strait of Juan de Fuca and rare in Puget Sound, particularly during and after fall storms.Text edited by Gussie Litwer
