Eggs of the Snow-Bunting are of a pointed oval shape and are 

 moderately glossy. The ground-colour is generally pale bluish- 

 white, but in some specimens it is yellowish-white or cream-colour. 

 The surface-markings, consisting of streaks, spots, and blotches, 

 are reddish- or orange-brown, and there are generally, in addi- 

 tion, some sharply-defined markings of deep chocolate-brown, but 

 these are almost entirely confined to the larger end of the egg. 

 The underlying markings, which are usually large and conspicuous, 

 consist of blotches and clouds of rich lilac-grey and pale purple. 

 The markings are always densest at the large end, where they are 

 often confluent and form a zone or irregular cap. 



The eggs measure from '8 to T05 in length, and from -6 to *68 

 in breadth.
