Hairy Woodpecker
(Picoides fillosus) Y |
 |
RANGE: Breeds from western and central Alaska, northern
Saskatchewan, and Newfoundland south throughout most of North
America to Central America and the Bahamas. Winters generally
throughout the breeding range, with the more northern
populations partially migratory southward.
STATUS: Stable population throughout most of its range.
HABITAT: Inhabits nearly all types of forest within its range,
preferring bottomlands with large mature trees. Generally more
abundant at the edge of woodlands.
SPECIAL HABITAT REQUIREMENTS: Nest trees over 10 inches dbh.
Strongest nesting habitat associations in (1) Mountain
hemlock montane forest, (2) Ponderosa-pine-dominant mixed
conifer forest, (3) Jeffery and Lodgepole pine forests, (4)
Ponderosa-lodgepole pine on pumice, (5) Subalpine scattered
trees and shrubs, and (6) Western riverine woodland.
NEST: Excavates cavities in snags or in live trees with decaying
heartwood. Usually chooses deciduous trees such as aspens,
ashes, elms, or cottonwoods.
FOOD: Consumes a diet that is about 80 percent animal food
(wood-boring beetles removed from dead and diseased trees are an
important source of food). Also eats other insects, fruits,
corn, nuts, and cambium.
