108 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
Seasonal variations : — Spring, autumn, and winter specimens are essentially 
similar to one another, but the birds taken in October and early November 
have the general coloring clearer, and that of the head and under parts a trifle 
ashier, than in those collected at other seasons. 
In the Cape Region the Gila Woodpecker has apparently much the same 
distribution as Dryobates lucasanus. Neither Mr. Belding nor Mr. Frazar 
found it in the higher mountains, but both note its abundance throughout the 
low country, and Mr. Frazar obtained many specimens at Triunfo which is 
within the lower edge of the oak belt. Mr. Belding traced it to about thirty 
miles north of Todos Santos on the Pacific coast, but it extends still farther up 
the Peninsula, for Mr. Bryant ‘found a few on Santa Margarita Island, and 
met with them generally along the overland route” —just how far to the 
northward he neglects to state, however. Mr. Anthony says that “the range 
of this species along the Pacific slope [of the Peninsula] is exactly coéxtensive 
with that of Cereus pringlei, becoming common with that cactus a short distance 
below Rosario and seldom if ever being seen at any distance from the shelter 
of its mighty branches.” 4 
The Gila Woodpecker is not, of course, confined to Lower California. Else- 
where it occurs more or less numerously in southeastern California, southern 
Arizona and western Mexico. It is apparently resident wherever found.

My Lower California specimens appear to be in every way identical with birds 
from Arizona and northern Sonora, Mexico. A pair from Alamos, southern 
Sonora, are much darker above, with the ashy of the throat and breast deeper 
and duller, and the under parts browner. If additional material from Mexico 
should show that these color peculiarities are constant they would be quite 
sufficient to warrant the separation of the birds which inhabit the region about 
Alamos. 
Individual variations: — Both sexes. The rump and upper tail coverts are 
sometimes distinctly (but always finely) barred with black, sometimes immacu-
