TUBE-NOSED SWIMMERS 



8()1). Pacific Fulmak. Fulmarus glaci- 

 alis glwpischa. 



This sub-species of the preceding, has a darker 

 mantle than the common Fulmar; it is found on 

 the northern Pacific coasts where it breeds on 

 the high rocky cliffs, the same as it's eastern 

 relative. They nest in large colonies, every 

 crevice in the rocks having its tenant. Their 

 flight is graceful like that of the Gulls, whiil 

 they closely resemble. They lay but a single 

 white egg, the average dimensions of which are 

 slightly smaller than those of the common Ful- 

 mar. Data. — Copper Is., Alaska. May 14, 1880. 

 Egg laid in a crevice among the cliffs. 



86". 1. Rodger's Fulmak. Fnlmarus 7-o(Igcrs. 



Range. — North Pacific, breeding in large nunv 

 hers on some of the islands in Bering Sea; soutli 

 to California in winter. Very similar to the two 

 preceding species except that the back is mixed 

 with whitish, it is not believed to have a dark 

 phase. Their breeding habits and eggs do not 

 differ from the common Fulmar. The eggs are 

 laid on the rocky cliffs during June.

87- Slender-billed Fulmar. Priocella glacialoides. 



Range. — Southern seas, appearing on the Pacific coast of the United States 

 in the summer. This species has a paler mantle than the others of the family, 

 and the primaries are black. The make-up and plumage of the whole bird is 

 more like that of the Gulls than any of the others. They probably breed in 

 the far south during our winter, although we have no definite data relative 

 to their nesting habits.
