_Food._--Mr. Howell (1932) states that “this large woodpecker
is a decidedly useful species. It never injures farm crops, but
feeds entirely in the forests, rendering good service there in the
destruction of wood-boring beetles. It eats, also, ants and wild fruits
and berries, including the fruit of the sour gum, tupelo gum, dogwood,
persimmon, frost grape, holly, poison ivy, sumac, and hackberry.” C.
J. Maynard (1896) says that they “are partial to the berries of the
palmetto, feeding, in Florida, upon little else when these are in
season.”
CEOPHLOEUS PILEATUS PICINUS (Bangs)
WESTERN PILEATED WOODPECKER
HABITS
In describing and naming this large, dark-colored race from the
Northwest coast region, Outram Bangs (1910) says that it is “as large
as, or even larger than, _P. pileatus abieticola_ (Bangs), but color
sooty black as in _P. pileatus pileatus_ (Linn.), the throat usually
much marked with sooty, and the sides and flanks but slightly marked
with grayish.”
Major Bendire (1895) writes of its haunts: “In the mountains of Oregon,
and presumably in other localities, the pileated woodpecker is most
frequently met with in the extensive burnt tracts, the so-called
‘deadenings,’ where forest fires have swept through miles of fine
timber and killed everything in its path. Such localities afford this
species an abundant food supply in the slowly decaying trees, and are
sure to atract them.”
Grinnell, Dixon, and Linsdale (1930) say that in the Lassen Peak region
in California “individuals of this woodpecker were found in or among
white firs, red firs, incense cedars, and yellow pines. Foraging birds
were often working on rotting stumps or logs close to the ground.
Almost invariably, even when in the tops of tall trees, the birds were
on dead or softened wood.”
_Nesting._--J. A. Munro (1923) says: “In southern British Columbia
nesting begins early in May. The nest is a chiselled hole in a
tree, fourteen to eighteen inches deep, cut occasionally in a green
cottonwood or poplar, more often in a dead pine or fir, and rarely in
any but the tallest trees and at a considerable distance above the
ground. On a cushion of fine chips three or four rose-white eggs are
laid.”
Carriger and Wells (1919) give an interesting account of the nesting
of the western pileated woodpecker in Placer County, Calif. The first
nest, containing young birds, was found early in June 1915. “The tree
stood about fifteen feet from the shore of the lake and in about five
feet of water. At its base the diameter was about eighteen inches, at
the nest entrance about ten. The tree was a live aspen. * * *
“The nest cavity was eighteen inches deep and six inches in diameter,
while the entrance was three inches in width. The entire excavation had
been made in live wood although there were plenty of large dead trees
near by.”
