Young birds are duller than adults and have brown eyes. The populations south of an area around the border of Honduras and Nicaragua are sometimes separated as a subspecies P. w. ridgwayi, but the separation of this form has been questioned.

The populations in southern areas, adjacent to the Honduras-Nicaragua border, are occasionally regarded as a subspecies P. w. ridgwayi, although the classification of this form has been subject to debate.
