This form has heretofore been confounded with penicillata or diluta., 
or both, and though to some extent intermediate between these two, is 
easily recognizable upon comparison. It seems to be nearest penicillata., 
from which it differs in the slightly paler, more uniform upper surface, 
and in the strongly cinnamomeous shade of the same parts, the exposed 
surface of the upper tail-coverts being cinnamon, instead of pinkish 
vinaceous. From hicornis it may be distinguished by its larger size, 
less uniform upper parts, more pinkish nape and occiput, and much 
more grayish coloration.
