OTHER PIGEON HYBRIDS AND BREEDING OF CERTAIN SPECIES. 



169 



Phaps chalcoptera. — ^A small amount of data for bronze-wing and crested pigeons 

 is of interest in connection with the question of the sex produced by the first and 

 second eggs of the clutch. Both these Australian species lay 2 eggs in a clutch. In 

 the bronze-wing the slender data would indicate (table 171) a decided tendency for 

 the first egg to produce a male and for the second egg to produce a female. It 

 will be noted that the apparent exceptions to be seen in pair 2 {A 1 and B 1) are 

 nevertheless clutches in which the second egg seemed weaker than the first; one of 

 these failed to develop and the other yielded a bird of unknown sex that died 

 when a week old. 



Fewer still are the data for the crested pigeon (Oeyphaps lophotes) . The sex of 

 the birds from the 2 eggs of the same clutch was learned in 3 cases; only one sex 

 arose from each of these clutches. (Sh 18/13)
