THIS Skua is a rare visitor on migration, breeding only 

 in the circumpolar district 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 a slight hollow in the ground lined sparingly with a little 

 dry grass. The old birds are very daring in defence of 

 their young. 



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

 with irregular blots of reddish brown.
