Stercorarius parasiticus (Linnaeus) 



This is a rare species to all our shores, but a few, chiefly 

 immature birds, visit the east coast yearly, and in some 

 seasons become quite common. It is a circumpolar species, 

 breeding on the tundras throughout Europe, Asia, and 

 America, and migrating in winter as far south as the basin
