Variations in both coloration and dimensions, according to locality, indicate the 
possibility that further subdivision of the species may be required. Specimens 
from St. Michael and one from St. Lawrence Island have very dark upper parts, the 
dorsal region being mostly black, with very little of rusty. Examples from Bering 
Island, Commander group, represent the opposite extreme, rusty predominating on 
the upper parts, except one specimen, which is almost precisely like one from 
Muller Bay, Alaska Peninsula.
