BIRD NESTING. 103 



August old and young all leave the cliffs and go out to sea 

 together. 



The wings of the Guillemot, though small, enable it to fly 

 with tolerable facility, but its true home is on the surface of the 

 sea and under its waters. No more interesting sight can be seen 

 than the movements of a Guillemot, as observed through the 

 glass sides of a tank. On the surface of the water it moves solely 

 by the action of the feet. When underneath, the feet are not 

 used, but the bird literally flies with great rapidity through the 

 water, capturing with the greatest facility any live fish that may 

 be put into the tank. As it proceeds a stream of air bubbles 

 escape from beneath the feathers, giving the bird a most 

 remarkable silvery appearance. Its movements under water are 

 quick and easy, and it usually remains submerged for about half a 

 minute.
