, CATALOGUE OF CANADIAN BIRDS. 45 



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 franklinii. No doubt the two are often 

 confounded. Its breeding range is in the 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 

 lOth and July lOth, 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 nth, 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. {Raine.) 



I noticed one of these birds flying overhead among a num- 

 ber of common Terns on the nth 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
