The eggs of the Sandwich Tern vary from a pointed oval form 

 to pyriform. The ground ranges from white, through cream-cojour 

 and pale buff, to brownish buff. The markings are very bold as a 

 rule and consist of spots and blotches of dark brown approaching 

 black, and underlying inky-purple. The size, shape, and distribu- 

 tion of the markings of both kinds present almost endless variations.
