PLATE CXLI. FIG. II. 
The Glaucous Gull, which breeds in Iceland, Spitz- 
bergen, and many other parts of the far north, selects 
places for its nest similar to those chosen by the gulls 
with which we are familiar, sometimes making its nest 
upon the sea-beach, and at other times upon the ledges 
on the face of a precipice or at its summit. Dr. Richard¬ 
son states that the Glaucous Gull is a common species in 
Greenland, Baffin's Bay, and the Polar Seas, where it 
breeds upon the precipitous rocks which form the coast. 
It will be seen by the egg of this species, figured in the 
plate, that it bears a near resemblance, both in size and 
colouring, to those of the greater black-backed gull: so 
much so, that both the figures will faithfully represent 
each species.
