Join BirdNote tomorrow, November 30th!
Illustrator David Sibley and actor H. Jon Benjamin will face off in the bird illustration battle of the century during BirdNote's Year-end Celebration and Auction!
After a Northern Flicker carves out a nest cavity, chances are the birds will use the cavity for just one nesting season. But the cavity may have a prolonged career as a home for small owls, bluebirds, swallows, and other birds - including the Bufflehead. Buffleheads - like the family seen here - are the only ducks small enough to use the cavities of flickers. Clear-cutting in some northern forests has reduced nesting habitat for flickers and Buffleheads alike. Both benefit when consumers choose paper products made from recycled paper.
Flickers and Buffleheads

[Woodpecker excavating nest hole]
Listen to one of nature’s most skilled carpenters at work. [Woodpecker excavating nest hole] A woodpecker – a Northern Flicker – is carving out a nest cavity. Clinging halfway up an old, dead tree, the bird uses its chisel-like bill to chip out a round entrance hole three inches across. [Woodpecker excavating] The flicker then excavates a cavity a foot or more deep inside the trunk – a safe haven for raising its young.
Chances are, the flickers will use this cavity for just one nesting season. But that cavity may have a prolonged career as a home for small owls, bluebirds, swallows, and other birds – including one very special duck. [Splash of Bufflehead]
In the boreal forest of northern North America, the small black-and-white duck named the Bufflehead nests almost exclusively in old flicker cavities. [Bufflehead vocalizations] A number of other ducks also incubate their eggs in tree cavities, but Buffleheads are the only ones small enough to use the cavities of flickers. [ Northern Flicker calling]
Yet clear-cutting in some northern forests has reduced nesting habitat for flickers and Buffleheads alike. Both benefit when consumers choose paper products made from recycled paper. [Woodpecker excavation sounds]
