The eggs of the Caspian Tern are very much larger than the eggs 

 of the Gull-billed Tern, but resemble them closely in shape and 

 coloration. They pass through the same variations as the eggs of 

 that species taken in Europe and Asia. Specimens measure from 

 2'3 to 2'75 in length, and from 1"7 to 1-9 in breadth.
