' These birds were rather too young for fertility to be at its greatest height in either. But the male was a weakened 

 inbred from an egg produced rather late in the season from an overworked pair. The female of the above pair became tuber- 

 cular, probably after most or all of the above eggs were laid. During the season of 1914 this male was kept with a mature 

 female jS(. alba (682) without any eggs whatever being produced. Thus we see another evidence of the weakness of this male 

 when in his third year.
