The eggs of the Yellow-billed Coot are oval, fairly smooth, and 

 almost devoid of gloss. They are of a rich creamy-buff colour, 

 speckled all over with pale purple and rich chocolate-brown. The 

 markings are very small and evenly distributed over the shell. The 

 three examples in the Collection measure respectively : 1'85 by 1*'5 ; 

 1-7 by 1-22; 1-85 by 1-28.

The eggs of the Grebes are of a lengthened elliptical or biconical 

 shape, the two ends being closely alike in contour. Some are of an 

 oval form, but they are in the minority. 



The true shell is generally of a very pale greenish-blue colour, 

 but in fresh eggs it is covered with a thin coat of chalky white 

 matter, which obscures or completely conceals it. At first the eggs 

 have little, if any, gloss. As incubation proceeds, however, the 

 calcareous covering is worn away, the shell turns to a yellowish- 

 brown, and eventually to a dark earthy-brown, colour, so that in 

 most cases the egg becomes very smooth and highly glossy. 



The eggs of the various species of Grebes resemble each other 

 closely, and they cannot be separated in any way except, in some 

 instances, by their size.
