All these forms are very similar in appearance, and 
it is not unusual to find in one locality a bird which, in 
color, may closely resemble those of some far distant 
locality. The most that can be said for these races is 
that they average lighter or darker—as the case may 
be—than certain other relations, the center of whose 
abundance may be far distant.
