Twenty-two eggs of this species taken in a marshy lake near 
Crane Lake, Assa., on June 14th, 1894, by Spreadborough. 
60. Bonaparte’s Gull. 
Larus philadelphia (ORD) GRay. 1863. 
Frequent on the Atlantic coast as far north as Newfoundland. 
Apparently quite common in the Gulf of St. Lawrence and not 
rare in Hudson Bay. A spring and fall migrant in Ontario. 
This species is found from Manitoba to the Pacific and a few 
doubtless breed in the prairie region, but its range is generally 
north of that of Larus franklini. No doubt the two are often 
confounded. Its breeding range is inthe wooded country extend- 
ing from Hudson Bay westward to the marshes of the Yukon 
where Dall found it breeding. It is rare on the coast of Alaska 
but common along the British Columbian coast and very common 
on all the lakes of the interior of that province. 
BREEDING Notes.—Thirty-seven nests were taken between June 
1oth and July roth, in the wooded country, in the vicinity of 
Fort Anderson and on the Lower Anderson River. The nests 
were all built on trees,from four to twenty feet from the ground, 
and with one exception were made of small sticks and twigs 
lined with hay and mosses. (Macfarlane.) 
Dippie reports this species breeding at Buffalo Lake, Alberta, 
July, 1895. 
On June 11th, 1891, I found a few pairs of this little gull 
breeding in company with Herring Gulls, Avocets and Common 
Terns on an island in a small lake north of Rush Lake, Assini- 
boia. (See “ Birdnesting in North West Canada,” page 57.) One 
specimen of the bird was procured to prove identity. This bird 
usually makes its nests in bushes and willows near the water, 
but in localities where there are no bushes it makes its nest on 
the ground like the other gulls. The eggs are similar to those of 
Franklin’s Gull, but are smaller in size. (Razne.) 
I noticed one of these birds flying overhead among a num- 
ber of common Terns on the 11th June, 1893. I was visiting some 
rocks on the St. Lawrence below Rockport, Ont., at the time, and 
from the way in which it hovered along with the Terns thought
