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 oécasionally 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,” 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 (’98, Blogg). 
“One of the most abundant gulls at Cobb’s Island, where 
numbers commence to breed about the 20th of June” (Birds 
Vas., 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 (’93), 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).
