Eggs of Sumichrast's Crackle vary from a regular oval to a 

 pointed oval shape, and are moderately glossy. One is blue, marked 

 at the broad end with a few black blotches, spots, and intertwined 

 lines which form an irregular wreath. It measures 1*17 by *8. 

 Some eggs have only a few spots and closely resemble eggs of the 

 Song Thrush (Turdus musicus). They vary from 1'04 to 1*16 in 

 length, and from '77 to '81 in breadth.

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 T3 in length, and from -8 to -9 

 in breadth.
