THE GUIvL-BILLED TERN. 555 



Range in Ohio. — "Accidental in winter on Lake Erie" (Wlieaton). A 

 single specimen said to have been taken at Cleveland by Mr. Winslow, but no 

 longer extant. 



THE Fork-tailed Gull is a bird of the Arctic regions, and our knowledge 

 of it is obtained almost entirely from the journals of Arctic travellers, dating 

 from that of the discoverer. Colonel Edward Sabine, in 1818. In common 

 with several other birds of this group, its under parts are suffused with a 

 delicate pinkish .or rosy blush during the actual breeding season. One ob- 

 server. Captain McFarlane, describes a male taken in July as "deeply tinged 

 with crimson." 



The species retires from the higher latitudes with the approach of winter, 

 but only a scattering few come as far south as our northern borders. The 

 bird's claim to recognition here rests solely upon Mr. Winslow's record of 

 an immature bird, taken in Cleveland harbor many years since, and for a 

 time preserved in the museum of the Cleveland Medical College.
