Sub-Family ANSERINtE. 



The eggs of the Geese of this Sub-Family are typically of a broad 

 oval form, but elliptical examples also occur. The shell is strong, 

 granulated, rather rough and fairly glossy. The eggs vary from a 

 nearly pure white to a pale cream-colour, but they soon become 

 stained with incubation. It is unnecessary to describe the eggs of 

 each species separately.
