1 68 Braislin, Long Zsla/td, N. 2"., Birds. [a"* 



Larus kumlieni. Kumlien's Gull is herewith definitely 

 recorded for the first time as a bird of Long Island. Dr. Jona- 

 than Dwight, Jr., whose paper on the plumages and moults of 

 North American Gulls is, we believe, in press, has examined the 

 specimen which I recorded in ' The Auk,' April, 1899, p. 190, 

 as " Larus leucopterus (or kumlieni)" Dr. Dwight's investigations, 

 which will hereafter enable one to identify the immature as well 

 as the adults of L. leucopterus and L. kumlieni, have determined 

 the differential diagnosis of the two immature birds heretofore 

 impossible. The color of the shafts of the primaries are, he finds, 

 invariably distinctive. 



Larus marinus. The first Great Black-backed Gull observed 

 this autumn at the western end of Long Island was seen by Mr. 

 Robt. L. Peavey, on Nov. 20, 1904, at Rockaway. The earliest 

 fall record of this bird for this locality which the writer knows 

 is November 3. Both these dates are considered early, the birds 

 rarely occurring here in abundance much before Christmas. The 

 northward departure occurs correspondingly early, March 13 being 

 the date on which the last bird has been seen. 



Larus argentatus. The common Herring Gull has been 

 rather common the summer through for the past three or four 

 years from Rockaway Beach to Montauk. Before this, one saw 

 them regularly in Peconic Bay and but rarely elsewhere, in sum- 

 mer. They do not nest on Long Island but the increasing num- 

 ber of ' left overs,' as the baymen term them, is taken to indicate 

 their increasing numbers elswhere, which we regard as due largely 

 to the efforts of the Audubon Societies, through their Treasurer, to 

 extend absolute protection to them along the whole Atlantic 

 coast, especially during the breeding season. 



Larus delawarensis. The Ring-billed Gull is not uncommon 

 in our locality in summer. At least 50 were observed July 4, 

 1902, at Freeport. One killed there on Sept. 5, 1901, was in an 

 advanced stage of moult, the throat being nearly bare. Imma- 

 ture and adult Ring-billed Gulls pass along this part of the coast 

 in large numbers in October, when they are also common in our 

 harbors. The last one was noted on November 17. The writer 

 has no record of this bird in winter for this locality. 



Larus atricilla. The only gull for which evidence still exists 

 to support a claim for it as a breeding species on Long Island,
