The eggs of the Collared Crow-Shrike are of an oval shape and 

 exhibit a considerable amount of gloss. They are very variable in 

 colour. The ground-colour in some eggs is olive-grey, in others 

 pale buff, and in others again olive or olive-buff. The markings 

 generally form a zone or cap at the broad end and consist of specks, 

 spots, blotches, and smears of deep purplish red, reddish brown, 

 umber-brown, and underlying lavender or lilac-grey. Specimens 

 measure from 1'17 to 1'25 in length, and from -87 to "92 in 

 breadth.
