The eggs of the Rufous-winged Buzzard-Eagle resemble those of 

 B. teesa, being of a very pale bluish-white colour. One specimen, 

 however, is marked with a few grey spots at the larger end, but these 

 are probably nest-stains. Three examples measure respectively : 

 1-84 by 1-45; 1-8 by 1-45: 1-71 by 1-41.

The eggs of the White-tailed Eagle are chiefl)' of a broad oval 

 shape, but sometimes they are elliptical or spheroidal. The shell 

 is coarse in texture and often possesses a considerable amount of 

 gloss. All the eggs of this Eagle in the Collection are plain white, 

 except one specimen, which is marked with spots and scrawls of 

 rufous at the larger end. Numerous examples measure from 2'7 

 to 3-b in length, and from 2-1 to 2'45 in breadth.
