Canary Mules. 363 



of this sort, but I am convinced that the one was a flecked 

 canary with a malformed bill, and the other a mule between 

 a canary and a greenfinch. 



For further information on the subject of hybrids, see the 

 chapter devoted to " Mule Breeding." 



The bullfinch and brown or grey linnet will breed together, 

 but their produce are rather rarce aves than specimens of 

 elegance. I have likewise seen a bird exhibited as a hybrid 

 between a yellow-hammer and a canary. I examined it very 

 carefully and could trace no characteristics of the last-mentioned 

 species. It appeared to me to be a yellow-hammer pure and 

 simple. I have never observed any amatory tendency to exist 

 between the yellow-hammer and canary, but the reverse.
