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

 when in his third year.

From 4/24/12 to 6/23/12 T. orientalis No. 101 was used as male parent; 6/25 to 10/11/12 T. orientalis 446, 

 a younger brother to 101, was used. With cf 446 it will be noted that this female was quite infertile. With 

 the more mature brother all her eggs (4) developed; two of these whose sex is known were males. Later in 

 the season this female (St. alba hybrid) mated to a St. alba produced mostly fertile eggs 4 of 5 tested and 

 3 young from this season and mating were females; a fourth young was probably a male. 



cf 26 has not a perfectly clear history; is probably a pure St. alba, about three years old; but possibly 

 he is a J alba, \ risoria hatched in 1906. Very pugnacious. 



9 414 = a J alba, 1 risoria. In breeding behavior these two birds resemble two pure alba (all of their 

 27 young, 1913 to 1914, were white).
