Picoides arcticus
- legendaris
- 92 km/h
- Risiko rendah
Specialist of recently burned forests. Three toes, jet-black back, and a taste for charred-wood beetles.
- Populasi
- ~1.7 million mature individuals; trend considered stable overall (slight increase, though 2012-2022 shows decline, with ~7.3% forest-cover loss over three generations)
- Habitat
- Boreal and montane/temperate coniferous forests (sea level to ~3,100 m elevation, high forest dependency); a fire-specialist that concentrates in recently burned stands, feeding on the wood-boring beetle outbreaks that follow forest fires and bark-beetle kills
- Fakta menarik
- Along with the American and Eurasian three-toed woodpeckers, the Black-backed Woodpecker has only three toes instead of the four found on most woodpeckers, an adaptation linked to its habit of clinging to and stripping bark from fire-killed trees.
- Sebaran
- Non-migratory resident across the North American boreal zone: Alaska and Canada south through the northwestern US, the Rocky Mountains and Sierra Nevada, and the northern Great Lakes/New England region (Wisconsin, Minnesota, Michigan's Upper Peninsula, the Adirondacks, New England); also occurs on St. Pierre and Miquelon. Extent of Occurrence of ~15,200,000 km².
- Makanan
- Primarily larvae of wood-boring beetles (families Cerambycidae and Buprestidae) and engraver/bark beetles (including mountain pine beetle), obtained mostly by scaling bark and pecking into dead/burned trees, with a smaller amount gleaned from branches
