The Arctic tern is a rare bird in this State. It is barely mentioned 

 by Lawrence and DeKay, and Bergtold gives it as an accidental visitant 

 near Btoffalo. Mr Butcher has one specimen, a male taken on Ram island 

 shoals, July i, 1884. According to Brewster, [B. N. O. C, 4:15], the Arctic 

 tern bred along the entire New England coast in 1878. It is a bird of 

 holarctic distribution, breeding northward to unknown latitudes, and 

 migrating southward in winter as far at least as Virginia on the American 

 coast. It is remarkable that so few specimens have been taken on our 

 coast, and those in summer!
