152 GULL. 



the others very slightly tipped with white; two or three of the 

 scapulars are also tipped with white. According to Brunnich, the 

 head and neck are marked in lines of ash-colour, but this is only 

 seen in incomplete birds. The female is smaller, and the young birds 

 at first are blotched, and spotted with brown, as in the Wagel. 



Inhabits Norway and Greenland ; in plenty at Lesser Cumbray, 

 in the Firth of Clyde; no other Gulls, not even the mottled ones of 

 their own species, on the Island.* Breeds in abundance on Ramsay 

 Island, in Pembrokeshire, and frequently with the Herring- Gull, but 

 less plentiful than the Black-backed, with which it never assoeiates.f 

 The eggs like those of the Herring Gull, but larger; the young of 

 both much alike: it is by far less numerous than the Herring Gull, 

 but much more plentiful than the Great Black-backed.

A bird under this title is mentioned by Capt. Sabine, which he 

 describes by comparison with the Herring Gull. In general character 

 of plumage they are not unlike, but without any black in the primary 

 quills ; the shade of ash-colour on the back, scapulars, and coverts, 

 varies in different specimens. The males about twenty-four inches 

 long, the females rather less ; extent of wing four feet and a half; 

 the wings longer in proportion than those of the Herring Species. 



These were abundant in Davis's Straits, and Baffin's Bay, sup- 

 posed to be specifically the same with the Herring Gull, but from 

 the effect of climate the black markings of the prime quills changed 

 to white. Mr. Pennant observes, that the Herring Gull inhabits 

 Greenland throughout the year ; but Mr. Sabine rather thinks that 

 it is not so, as not a single one has been seen there with the black 

 prime quill feathers; and that it is most probable to be the one he 

 here describes. These were seen near Bear Island, with their young, 

 the end of August. %
