YOUNG BIRDS IN THE NURSERY 85 



colonies an unavoidable necessity. The sooty-grey chicks 

 in the third week in January, Dr. Wilson tells us, were 

 almost as big as their parents, and quite as active ; they 

 swarmed in thousands, and all were hungry, many very 

 hungry. 



" Moreover, each individual chicken acted on the 

 assumption that every old bird, as it came from shore, was 

 full of shrimps. On this assumption it had no choice but 

 to run the gauntlet. Chased incontinently ... by the 

 unfortunate infants, the fond parent ran hither and thither 

 with a keen eye for the chicken it had once called its own. 

 Driven at last to bay, it could only turn to swear, and

 a vicious peck ; but the moment its search again com-

 parent, with its little following of hungry chicks, intent 

 on one thing only, rushed quickly by, and the starveling 

 dropped behind to gather strength for one more effort. 

 Again it fails, a robuster bird has forced the pace, and 

 again success is wanting to the ' runt.' Sleepily it stands
