29 ('95), but in fall they are noted near Fort McHenry from 

 September 26 ('94) to November 6 ('94). 



Mr. Ridgway writes me : "As to Larus delawarensis wintering 

 near Baltimore, it may occasionally do so, but not in any con- 

 siderable numbers. Here, on the Potomac, it is not considered 

 a winter resident, though it migrates northward very early in 

 spring/ 7 and Mr. C. W. Richmond writes: "Not a winter 

 visitant at Washington, it was common during March until the 

 30th, 1890. Noted from February to April 5, and again in 

 October and November." 



Larus atricilla (58). Laughing Gull. 



Common migrant from April 28 ('94, Wholey) to May 22 

 ('95), and from September 29 ('94) to October 12 ('94). 

 A few may spend the summer with us, two pairs being noted 

 at Patapsco Marsh on July 3 ('93, Blogg). 



" One of the most abundant gulls at Cobb's Island, where 

 numbers commence to breed about the 20th of June" (Birds 

 Yas., 41). I have been told they breed at Chincoteague Island, 

 and from the fact that I saw a few flying north in the morning 

 and south in the evening over Chincoteague Bay, in Maryland, 

 I presume they do, though a search of ten days (June 5 to 14, 

 '94) failed to locate a breeding site on the ocean front of 

 Maryland, and I also failed during two seasons ('92 and '93) 

 to locate a breeding site on the Chesapeake, though frequently 

 told of them by the fishermen, and frequently seeing paired birds. 



Larus Philadelphia (60). Bonaparte's Gull. 



A tolerably common migrant, noted from March 24 ('94, 

 Fisher) to May 17 ('9 3), -and from October 5 ('94) to November 

 9 ('92, Resler) ; a few may also winter with us (Birds N. W., 638). 

 While this species may come up the harbor with the Herring 

 Gulls, I do not think it ever comes beyond the broad water at 

 Broadway Ferry. At Washington they are given as "compara- 

 tively common in August and September" (A. C., 108).
