Larus leucopterus. Iceland Gull. On April 19, 1915, I saw a 
beautiful entirely snow white Iceland Gull sitting beside a Herring Gull, 
on the breakwater off Rockport, Mass. At the distance seen, about fifty 
yards, the bill was conspicuously all black, the back looked the same as 
the breast snow white and when the bird flew I saw that the ends of the 
wings were white. 
On Jan. 22, 1916, near the Salvages off Rockport, Mass., I saw six Iceland 
Gulls. The birds were flying about, among a large number of Herring 
Gulls, and were seen near enough to positively identify them, allowance 
being made for seeing the same bird twice, in giving the probable number 
of six. Two of the birds were taken, both males, one of which was an adult, 
with mantle pale pearl-blue and fresh color of bill a very delicate shade of 
fight green, with yellow spot, almost an orange shade, on the lower mandible 
near angle, and a fighter yellow spot, somewhat diffused and not as pro¬ 
nounced, on the upper mandible just over the spot on the lower mandible. 
The measurements and weights of the two birds were practically the same. 
On May 13, 1916, near the Salvages off Rockport, Mass., I saw an Ice¬ 
land Gull, near enough, several times, to positively identify the bird. 
On Feb. 22, 1917, in the same locality, I saw an Iceland Gull, which came 
within thirty-five yards of the boat. 
On Feb. 4, 1918, a short distance off Rockport, Mass., I saw three Ice¬ 
land Gulls, two of which were taken, both immature males. 
On Feb. 11, 1918, same locality, two immature female specimens taken.
