Life histories of North American woodpeckers

Birds -- North America; Woodpeckers -- North America
The range of the downy woodpecker is =north= to Alaska (Russian
Mission, Tanana, and Fort Egbert); southwestern Mackenzie (Fort Simpson
and Fort Providence); northern Alberta (Fort McMurray); central
Saskatchewan (Big River and Prince Albert); southern Manitoba (Lake St.
Martin, Shoal Lake, and Indian Bay); Ontario (Lac Seul, Gargantua, and
Sudbury); Quebec (Lake Mistassini, Godbout, and Natashguan River); and
Newfoundland (Nicholsville and probably St. Johns). The =eastern= limit
of the range extends =south= along the Atlantic coast from this point
to southern Florida (Miami, Royal Palm Hammock, and Flamingo). From
this southeastern point the species is found westward along the Gulf
coast to Mississippi (Biloxi) and Louisiana (New Orleans), thence in
the interior to south-central Texas (Giddings and Pecos); southern New
Mexico (Mayhill, Cloudcroft, and Silver City); Arizona (San Francisco
Mountain and Fort Valley); and southern California (Escondido). The
=western= limits extend nearly or quite to the Pacific coast north
through California, Oregon, Washington, and British Columbia to Alaska
(Sitka, Sitkalidak Island, Bethel, and Russian Mission).
The range as above outlined is for the entire species, which has been
separated into six subspecies. The typical form, the southern downy
woodpecker (_D. p. pubescens_), is found in the South Atlantic and
Gulf States north to North Carolina and Oklahoma; the northern downy
woodpecker (_D. p. medianus_) ranges north from Virginia, Tennessee,
and Kansas (casually eastern Colorado) north to southern Alberta,
Manitoba, Quebec, and Newfoundland; Nelson’s downy woodpecker (_D. p.
nelsoni_) ranges southeast from northwestern Alaska to central Alberta
and is found casually even farther east; Batchelder’s woodpecker (_D.
p. leucurus_) is the Rocky Mountain form and is found from the Kenai
Peninsula of Alaska south to New Mexico and Arizona, casually east to
Nebraska and on the coast of British Columbia; Gairdner’s woodpecker
(_D. p. gairdneri_) is found on the Pacific coast from British Columbia
south to northern California; and the willow woodpecker (_D. p.
turati_) is confined to California, being distributed rather generally
over the State except in the desert areas and the northwestern part.
While the downy woodpecker is not migratory in the accepted sense of
the term, and during the months of November and December has been
recorded north to Mackenzie (Fort Simpson) and central Quebec (Lake
Mistassini), it appears to have some local movements and seems given
to a certain amount of wandering after the close of the breeding
season. In some of the more northern areas it is commoner in winter
than in summer, while in the mountainous regions of the West there is
apparently a vertical movement in winter to the valley floors.
