In North America this Woodpecker is considered a race of Dendrocopus villosus 
(Linn.), a very variable form divided into six subspecies by Mr. Ridgway, and an equal 
number by Mr. Hargitt, but of rather different relative value. Thus D. villosus, besides 
the typical bird, has a large northern and a small southern form, called respectively 
by Mr. Ridgway D. villosus, D. v. leuwcomelas, and D. v. auduboni, the other three forms 
being subsp. « D. maynardi, Hargitt,=D. v. maynardi, Ridgw., subsp. B. D. harrisi, 
Hargitt, = D. v. harrisi, Ridgw., and subsp. y. D. jardinii, Hargitt, = D. v. jardinit, 
Ridgw. We have here only to do with the two latter birds, which we may call 
Dendrocopus harrisi and D. jardinii, nothing resembling the true D. villosus occurring 
within our limits. 
D. harrisi is restricted to the Northern and Western States of Mexico, as far south 
as the sierras of Jalisco; birds from this district can be distinguished without much 
difficulty by the lighter purer white of their light markings, which show but a slight 
tinge of the smoky tint which pervades D. jardinit. 
Specimens from the more southern districts of Jalisco and Colima are slightly darker 
than more northern birds, and thus there is an area within which D. harrisi passes 
into D. jardinit. In Eastern and Southern Mexico all the birds are undoubtedly 
D. jardinit.
