402 TEN YEAES IN SWEDEN. 



certain localities. One thing, however, is certain, that in 

 1862, we had a migration of lemmings at Quickiock, and 

 that year in one fell meadow, a little distance from the 

 village I shot about twenty-five old birds, and procured 

 above thirty eggs. I got the first nest on June 3rd. I never 

 but once found more than two eggs in a nest ; the nest is 

 nothing more than a few pieces of dry hay scratched 

 together on the ground, generally near water, never on 

 the real snow fells. Although they breed in colonies, I 

 never found two nests close together. In the young birds 

 just flyers, the plumage much resembled that of the common 

 skua, and the tail was perfectly even.

Much resemble the gulls; the beak, which is as long 

 as the head, is in shape more like that of the skua, but 

 the nail or hook on the end is much more developed, 

 and the nostrils form a single tube, which opens out in 

 the middle of the upper mandible; wings long, first 

 feather longest; tail rounded, or wedge shaped, fourteen 

 feathers ; the sexes do not differ in plumage, and the young 

 are more grey, but much resemble the old birds.

 mar Petrel. D. F. 



Ash blue above, with dark wings; below white; 

 point of the beak, legs, and feet, yellowish ; eye brown, 

 becomes yellow with age ; primaries dark grey ; beak 

 1 in. 4 1. long at the root, thick and round, 6J 1. high 

 and the same broad; about the size of the common 

 gull; length 18 in. ; tail 5 in. shorter than the wings; 

 tarsus 2 in. ; nasal tube 3|- 1. broad. 

 Is not seen on the Swedish coasts in summer, but occa- 

 sionally in autumn and winter. Never further south on 

 the Norwegian coast than Trondtheim. Breeds in the far 

 North in the islands off Norrland and Finland, but Iceland 

 appears to be the principal breeding place of the fulmar 

 petrel. The female lays one white egg, without any nest ; 

 3 in. long, 2 in. broad.
