Eggs of the Urraca Jay vary in shape from a broad to a somewhat 

 pointed oval, and are slightly glossy. The ground varies from 

 greyish-white to creamy-white and whitish-buff, and is generally 

 thickly freckled all over with yellowish-brown and lilac-grey, the 

 markings being usually most numerous at the broad end. In some 

 clutches the markings are small and comparatively speaking few, 

 in others they are much coarser and have a somewhat blotched 

 appearance. In one abnormally coloured set the ground is pale 

 bluish-white with small very dark brown spots and ash-grey under- 

 markings, mostly concentrated about the large end. They vary 

 in length from 1-18 to 1-4, and in breadth from -88 to -98.

Two eggs of the Colombian Jay do not differ in any way from 

 typical examples of C. chrysops, with the ground-colour whitish- 

 buff. They measure respectively : 1-36 by -96, and 1-32 by -99.
