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 

 purplish-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 irom -8 to -9 

 in breadth.
