EGGS OF THE GUILLEMOT 



These show an extraordinary range of variability, both in marking and in colour. Browns, yellows, reds, greens, blues, and white* 

 are found, and they may be blotched, spotted, lined, or streaked. The shape is believed to serve a useful purpose in preventing the egg 

 from rolling except in a small circle and thus from falling off the cliff ledge on which it is laid.

 STRANGE NEST MATERIALS OF A CARRION-CROW 



Some nests are composed of the bones of departed birds and mammals. There may be also 

 quantities of string, cigarette packets, and even, in one case, a lady's handkerchief.
