BirdNote: Woodpeckers as Keystone Species

Woodpeckers – including this Northern Flicker – are master carpenters of the bird world. They’re called “keystone species” for their crucial role in creating habitat suited to other woodland wildlife. Abandoned woodpecker nest-holes become nests or roosts for small owls, cavity-nesting ducks, swifts, bluebirds, swallows, wrens, and other birds, as well as many small mammals.
