The eggs of the Little Gull are very varied. Many are of a 

 regular oval form, but the majority are pointed at the smaller end. 

 The ground varies from pale buff to brown and olive-brown. The 

 markings are dark brown, frequently approaching black, and under- 

 lying pale purple. They vary in size from spots to large blotches, 

 and are fairly equally distributed over the whole shell. The eggs 

 measure from 1"5 to 1'75 in length, and from 1-13 to 1-23 in 

 breadth.
