Life histories of North American woodpeckers

The Gairdner, Willow, and Batchelder Woodpeckers in the
orchard are worth their weight in gold to the fruit grower.
They should be strictly protected, and every known means of
attraction should be used in the attempt to persuade them
to remain about the ranches.
_Winter._--Anderson and Grinnell (1903) say that, in the Siskiyou
Mountains, Calif., “the Gairdner woodpecker is usually to be found in
company with the flocks of mountain chickadees which frequent the black
oak groves all winter. The oaks are their favorite working places, but
they are also to be seen among the pines and spruces. Six specimens
brought home are all quite near _gairdneri_. The smokiness of the lower
surface is not so intense as in skins from western Oregon, but the
size, especially of the feet, is decidedly that of the northwest coast
form.”
DRYOBATES PUBESCENS LEUCURUS (Hartlaub)
BATCHELDER’S WOODPECKER
HABITS
The downy woodpecker inhabiting the Rocky Mountains and adjacent
regions from southern Alaska to Arizona and New Mexico is described by
Ridgway (1914) as “similar in large size and whiteness of under parts
to _D. p. nelsoni_, but with less of white on wing-coverts, sometimes
with none, the spots, when present, only on terminal or (usually)
subterminal portion, and on only a few of the covert features.” It
also differs from it in a “tendency to reduction or absence of bars on
lateral rectrices.”
The common name of this woodpecker is in honor of Charles F.
Batchelder, who first (1889) called the attention of American
ornithologists to the characters of this race under the name _D. p.
oreoecus_. Batchelder’s name was used in the 1895 A. O. U. Check-List,
but it was later found to be antedated by _Dryobates homorus_ of
Cabanis and Heine, which was adopted in the 1910 Check-List. This was
found to be still further antedated by the name _Picus leucurus_, given
to the downy woodpecker of the Rocky Mountains by Hartlaub in 1852. It
seems rather strange that this race remained so long unrecognized in
this country. This may be due to the fact that this woodpecker seems to
be a comparatively rare bird throughout most of its range.
The Weydemeyers (1928) say of its occurrence in northwestern Montana:
A rather rare permanent resident, irregular in winter.
Occurs throughout the county, but is rare at high
elevations. It frequents mixed broad-leaf and conifer woods
along the lower streams, where it undoubtedly breeds in
preference to other locations. During winter it is often
seen about farmsteads and pastures, and in bordering woods
of Douglas fir, yellow pine, and larch. In the Canadian
zone it occurs sparingly in lodgepole pine and alpine fir
(_Abies lasiocarpa_) woods, usually along streams.
