Mr. Selby on the Birds of the Farn Islands, 461 



For many years these birds bred upon one of the outer islands, 

 called the Longstone ; but having been repeatedly disturbed and 

 deprived of their eggs, they removed this last season to the 

 northern Walmsey. They breed in company, and their nests are 

 frequently close to each other ; they are composed of a great mass 

 of sea tangle, and are frequently two feet in height. They lay 

 from four to six eggs, of a small size in proportion to the size of 

 the bird, thickly coated with a rough, white, calcareous deposit. 

 The young, when first excluded, are blind, and covered with a 

 blueish black skin j in the course of a few days they acquire a 

 thick covering of black down, and are sufficiently fledged to take 

 to the water, though still unable to fly, in the space of three 

 weeks or a month.

A few pairs annually breed in the clefts and upon the ledges 

 of the Pinnacles, and the rock opposite to them ; their eggs are 

 very like that of the Great Cormorant. The large projecting 

 crest upon the forehead, a distinguishing character of this species, 

 is confined to the breeding season. It was long confounded with 

 the Carbo Graculus (Shag) of authors.

This species which has long been confounded with Sterna 

 Hirundo (the Common or Greater Tern) was first indicated and 

 described as a distinct species by M. Temminck, in the 2d edit, 

 of the Manuel d'Ornithologie. It differs from it in having a bill 

 somewhat shorter, and generally wholly red ; shorter tarsi, and 

 the breast and under parts of as deep a grey as the back. The 

 outer tail feathers are also longer, and project further beyond the
