2 I have been unable to discover any infallible or positive difference in plumage between the females of A . 

 tricolor and A. gubernator, except that in the texture, which can only be depended on as a test after one has 

 become used to comparing specimens ; the female of A. gubernator averages decidedly browner, however, with 

 relatively shorter and stouter bill, usually more rounded tail, and slightly shorter tarsus.
