THE O. & O. SEMI-ANNUAL. 21 
back to the hotel, ordered my horse and drove homeward. On 
arrival home there was a letter from a friend, stating he had a 
white owl for me. Two weeks later I received a fine specimen 
from Yorktown, N. Y. It is now mounted and in my collection. 
The measurements were as follows: extent, 5 ft. 8 in. ; length, 
28 in. ; tail, 9 in.; male. 
The plumage of this species is almost pure white, marked by 
dusky-brown on some of the feathers of head and back. The fe- 
male is much darker than male, only the face, fore neck, middle 
of breast and feet being white; the other parts being heavily 
barred with dusky. 
The eggs are 5—10, 1.76x2.24, pure white. 
AMONG THE GULLS AT DUCK ISLAND. 
BY CHAS. S. BUTTERS, HAVERHILL, MASS. 
My article in the last number of the Srm1-ANNUAL, described 
a visit I made to an island off Portland Harbor, and securing a 
number of eggs of the Common Fern and Leach’s Petrel. 
After leaving that island, we started down the coast, headed 
for Mt. Desert, Me. It must be remembered that this was a fish- 
ing trip, and being the only oologist on board, I could not spend 
the time collecting that I wished to. 
The coast from Portland to Mt. Desert is lined with islands, 
large and small. I think these islands would make good collect- 
ing grounds, but as it was rather late in the season I could not do 
much. I heard that on one of the islands, the year before, the 
American Herring Gull had been found breeding in large num- 
bers. That was the island I wished to visit. 
During the next few days I went ashore on quite a number of 
islands, finding a few Tern’s eggs, and on one island I found a 
solitary nest of the Herring Gull, containing two eggs, which I 
collected. Not far from this nest some of the men found a_ pair 
of young gulls, about two-thirds grown. After a long chase they 
were captured and brought on board.
