The Iceland Gull builds on the face of a precipice 

 or cliff, but at a rather low height. It shares the place 

 with other species. 



The eggs are of an olive green colour, spotted with 

 two shades of brown. 



The Rev. H. B. Tristram has favoured me also with 

 the egg of this bird to be made use of for the plate. 

 It was procured from the White Sea in 1852.
