- Populasi
- ~11 million global breeding individuals; range-wide trend stable to slightly increasing 1966-2019, with regional declines in parts of the interior US
- Habitat
- Mature and old-growth coniferous, deciduous, and mixed forests with large-diameter trees and deeply furrowed or loose/peeling bark for foraging and nesting; also uses parks and wooded suburban areas in winter
- Fakta menarik
- Brown Creepers forage by spiraling up a tree trunk probing bark with their thin, downcurved bill, then fly to the base of a neighboring tree to start the climb again, and build hammock-shaped nests tucked behind slabs of peeling bark rather than in cavities.
- Sebaran
