PART II 



DOMESTIC LIFE OF THE 

 ADELIE PENGUIN 



Laying and incubation of the eggs : The Adelies' 

 habits in the water : Their games : Care of the young : 

 The later development of their social system. 



On November 3 several eggs were found, and on 

 the 4th these were beginning to be plentiful in 

 places, though many of the colonies had not yet 

 started to lay. 



Let me here call attention to the fact that up to 

 now not a single bird out of all those thousands 

 had left the rookery once it had entered it. Con- 

 sequently not a single bird had taken food of any 

 description during all the most strenuous part of 

 the breeding season, and as they did not start to 

 feed till November 8 thousands had to my know- 

 ledge fasted for no fewer than twenty-seven days. 

 Now of all the days of the year these twenty-seven 

 are certainly the most trying during the life of the 

 Ad^lie.
