The eggs of Richardson's Skua are of a pointed oval form, some- 

 times broad and at other times lengthened and narrow. The ground- 

 colour varies from greenish grey to dark olive and russet-brown. 

 The markings consist of spots, blotches and smears, and are of a 

 yellowish brown or brown of various shades, sometimes approach- 

 ing black. The underlying markings are seldom conspicuous, and 

 are of a pale purple colour. The markings of both kinds are 

 generally evenly distributed over the shell, but in many cases they 

 are collected chiefly at the larger end, where they form an irregular 

 cap or zone. The eggs measure from 2 to 2-5 in length, and from 

 1-47 to 1-7 in breadth.
