A medium-sized predominantly brown and
white montane woodpecker, the Arizona Woodpecker is one of
several primarily Mexican species whose range barely extends
into the southwestern U.S. It is found from southeastern Arizona
and adjacent New Mexico south into Mexico along the Sierra
Madre Occidental. An uncommon species, it is found primarily
in dry pine-oak habitat and adjacent riparian woodlands, most
often at elevations of 1,500-1,700 m, but as low as 900 m
and as high as 2,500 m in Mexico.
Though resident in its range, it sometimes
moves downward into oak woodlands during the winter, possibly
in response to food shortage. Though the U.S. populations
seem to be relatively stable, living in rough terrain and
in woodlands of low commercial value, the habitat for the
bird in northwestern Mexico is being decimated by rapid growth
in human populations with a resultant rapid rate of deforestation.
In Arizona, it excavates nest cavities in evergreen oaks,
sycamores, walnuts, maples and cottonwoods but apparently
does not reuse these cavities. It is secretive and inconspicuous
during nesting.
There is no information on population trends
in the U.S. and little information in general about the species
in Mexico, though habitat fragmentation and lumbering resulting
from increased rural development there may result in diminishing
populations. Heavy grazing and lowering of the water table
may harm the bird in both countries, since sycamores, which
require a permanently high water table for seedling survival,
are particularly important to the bird.
