The eggs of the Purple Grackle, or Changeable Troupial, are 
mostly of a regular oval shape and moderately glossy. The ground- 
colour is of some shade of green, varying from greenish-white and 
greyish-green to pale greenish-blue. The markings are coarse and 
consist of blotches and thick twisted lines of black and deep 
purplisn-brown. Most specimens are also marked with smears and 
clouds of various shades of brown, chiefly pale, and some spots and 
blotches of underlying lavender. A few examples are mottled all 
over with pale reddish-brown to such an extent that little of the 
ground-colour is left visible. On these, the dark blotches and lines, 
so characteristic of most of the eggs of this species, are entirely 
absent. ‘They measure from 1-1 to 1:3 in length, and from °8 to -9 
in breadth.
