THIS Skua Gull breeds on the shores of the sea, and those of the 

 larger rivers, as also on barren heaths at some distance inland: many- 

 birds build together. The nest is composed of dry grass. 



The eggs are in number two, of a pale olive green colour, with 

 irregular blots of reddish brown.
