120 AMERICAN SQUAB CULTURE 



The fact that a female will mate up about two weeks younger 

 on an average, than a male, reduces the chance for brother to 

 mate with sister. This is caused by the habits of birds more 

 than by the age that male and female mate. A male will gen- 

 erally get a home or a nesting place before he gets a mate. In 

 fact, this is generally the way he gets a mate (see article on 

 mating), while a female will mate up with some older male that 

 has a home to take her to about the time her nest brother is 

 thinking of getting a home.
