The eggs of the Common Gull are not subject to any great 

 variation iu coloration. An occasional blue egg rnay be found, 

 but the majority are much of one type. The ground varies between 

 dark cream-colour and olive-buff and olive-brown. The surface- 

 markings are dark brown, sometimes approaching black, and the 

 underlying markings are grey or pale purple. In most examples 

 the markings, consisting of spots and blotches, are pretty evenly 

 distributed over the shell ; in a few, the blotches are larger and 

 collected together chiefly at the larger end. The eggs measure 

 from 2'15 to 2-6-5 in length, and from 1-6 to 1"75 in breadth.
