 breeding place seen. {A. P. Low.) These birds were first observed 

 at Bonne Bay, Newfoundland, in August, and from this point

 May 13th and became more common until the last of the 

 month ; abundant at St. Lawrence Island and everywhere in 

 Behring Strait ; very numerous along the Arctic coast on the 

 borders of the ice-pack. {Nelson.) Arrives at St. Michael

 the lowlands, usually solitary, but several may be seen together 

 at one time in the neighbourhood. {Turner.) A regular summer
