132 C. H. Merriam Birds of Connecticut. 



268. Lams marinus Linne. Great Black-backed Gull. 



A winter resident; not rare. Linsley records it from Stratford, 

 Conn. During January, February and March, one frequently sees 

 two or three Larus marinus flying about the Harbor in company 

 with the common Herring Gulls. 



269. Larus argentatus, var. Smithsoniaiins Coues. Herring Gull. 



An abundant winter resident. Arrives from the North in October, 

 remaining till April or May. Have seen hundreds of them together 

 in New Haven Harbor in February and March. Mr. Thomas B. 

 Osborne has seen them in June and early September, and a few 

 doubtless spend the summer, but they are probably young birds and 

 do not breed. Dr. Wood occasionally finds it about the Connecticut 

 River above Hartford. On June 29th, 187 7, T saw five together near 

 Faulkner's Island, Conn. Four of these were in the young (gray) 

 plumage, while one was white. 



270. Larus Delawarensis Ord. Ring-billed Gull. 



Not rare. Linsley found it at Stonington, Conn. The young of 

 this species, easily recognized by having " a broad, subterminal band 

 of black" across the tail (Coues), may frequently be seen in winter 

 associated with the foregoing. My attention was first called to it by 

 Mr. E. P. Bicknell, of Riverdale, N. Y. 



271. Larus tridactylus Linne. Kittiwake Gull. 



Occurs in winter, but is not common. Linsley gave it from Ston- 

 ington, Conn. Mr. Osborne has seen it from March 8th till April 

 14th. 



272. Larus atricilla Linne. Laughing Gull. 



Not common. Possibly a few breed on some of the islands oif 

 our coast. Linsley states that they were occasionally killed at Ston- 

 ington, Conn. Mr. Osborne informs me that he saw one June 1st, 



1876. 



273. Larus Philadelphia (Ord) Gray. Bonaparte's Gull. 



Is tolerably common in fall. Captain Brooks writes me that they 

 are " quite common about Faulkner's Island, Conn., in October and 

 November," and that he occasionally sees them " with Terns at Goose 

 Island, Conn., in summer." Linsley states that he "obtained an
