Life histories of North American woodpeckers
Bent, Arthur Cleveland
Birds -- North America; Woodpeckers -- North America
The range of the hairy woodpecker extends =north= to Alaska (Kenai
Peninsula, Fairbanks, and Fort Egbert); Yukon (Forty Mile, Fort
Reliance, and Macmillan River); Mackenzie (Fort Wrigley, Lake Hardisty,
and Fort Resolution); northern Saskatchewan (mouth of the Charlot River
and Poplar Point); northern Manitoba (Grand Rapids, probably Fort
Churchill, and probably York Factory); Ontario (Hat Island and Cobalt);
Quebec (Blue Sea Lake, Quebec City, Godbout, Eskimo Bay, and Anticosti
Island); and Newfoundland (Nicholsville and Raleigh). From this point
the range extends =southward= along the Atlantic coast to southern
Florida (Eau Gallie); the western Bahama Islands (Great Bahama, Abaco,
and Andros); and Panama (Boquete). The =southern= boundary of the range
extends westward from Panama (Boquete); Nicaragua (San Rafael); western
Guatemala (Tecpam); Chiapas (San Cristobal); to Guerrero (Chilpancingo
and Omilteme). From this point, =northward= through the mountains of
western Mexico, northern Baja California (Sierra San Pedro Martir
and Sierra Juarez); and the coastal districts of California, Oregon,
Washington, and British Columbia, to Alaska (Chilkoot, Chitina Moraine,
and the Kenai Peninsula).
As outlined, the range is for the entire species, which has, however,
been so divided that no less than 13 subspecies are currently
recognized as occupying the range north of Mexico, while still others
occur in Central American countries. The typical eastern hairy
woodpecker (_D. v. villosus_), occurs in the Eastern United States
and southern Canada west to Manitoba, North Dakota, and Colorado
and south to North Caralina and central Texas. The northern hairy
woodpecker (_D. v. septentrionalis_) occupies the zone to the north,
from southeastern Quebec, northwestward to western Mackenzie, Yukon,
and central Alaska. The Newfoundland woodpecker (_D. v. terraenovae_)
is found only on the island of that name. The southern hairy woodpecker
(_D. v. auduboni_) occupies the southeastern part of the range from
Missouri, Illinois, and western Virginia south to southeastern Texas
and southern Florida. The Sitka hairy woodpecker (_D. v. sitkensis_) is
found in southeastern Alaska and northern British Columbia. The Queen
Charlotte woodpecker (_D. v. picoideus_) is found only on the group
of islands of that name off the coast of British Columbia. Harris’s
woodpecker (_D. v. harrisi_) occupies the coastal regions of southern
British Columbia south to northwestern California. Cabanis’s woodpecker
(_D. v. hyloscopus_) is confined to certain coastal and mountain areas
of California, chiefly in the southern part. The Lower California hairy
woodpecker (_D. v. scrippsae_) is restricted to the Sierra Juarez and
the Sierra San Pedro Martir of Baja California. The Modoc woodpecker
(_D. v. orius_) is found in the Sierra Nevada of central California
north to Oregon and Washington and east to Nevada. The Rocky Mountain
hairy woodpecker (_D. v. monticola_) is found through the Rocky
Public-domain text, read in full here on John Shaqi.
