Eggs of the Common Magpie are generally of a regular oval 

 shape, but some specimens are more elongate and somewhat 

 compressed towards the smaller end. They are distinctly glossy. 

 The ground is almost invariably pale green or greenish-white, 

 occasionally pale bluish-white, and is usually marked all over the 

 shell with spots and small blotches of umber-brown, or dark brown 

 and pale lavender-grey. The markings vary a good deal in size, 

 being very small and numerous in some examples and larger and 

 fewer in others ; while in some they obscure the greater part of 

 the ground. In one rather peculiar clutch from Alton the ground 

 is of rather bright a olive-green, and the markings are mostly 

 concentrated at the larger end, forming a dark cap. The markings 

 are occasionally most numerous at the smaller end. They vary in 

 length from 1-22 to 1-47, and in breadth from -92 to 1-0.
