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.
