Saving the Red-cockaded Woodpecker
A woodpecker sets up a roadblock!

After carving a nest cavity in a living tree, which can take a year or more, Red-cockaded Woodpeckers peck holes around the nest, causing sap to flow downward. This creates a barrier to thwart hungry snakes. The mature longleaf pine woods where these endangered birds live are shrinking. Recovery efforts have been slow, but the birds will inhabit man-made nest cavities, resulting in an increase of nesting pairs in some areas.

Saving the Red-cockaded Woodpecker
Written by Bob Sundstrom
This is BirdNote.
[Southeastern forest ambient]
In a Southeastern forest, a six-foot-long rat snake slithers up the trunk of a large longleaf pine tree. The hungry snake is climbing the rough bark toward a woodpecker’s nest hole for a meal of eggs. But the snake’s in a sticky situation — literally. A few feet below the nest, the snake encounters a sheet of pine sap, a roadblock that sends it back down the tree, hungry.
The nest belongs to a family of Red-cockaded Woodpeckers. After excavating a nest cavity in a living tree — which can take a year or more — the birds peck holes around the nest cavity, causing sap to flow downward, a barrier to climbing predators.

The mature, open longleaf pine woods the woodpeckers require are largely gone, and the birds have been designated as endangered for more than 50 years.
There is some good news: the woodpeckers seem happy to inhabit man-made nest cavities cut into large trees. And the number of nesting pairs has increased in some areas.

If more of their forest habitat is protected, these rare woodpeckers will have an even better chance at survival. After all, they’ve already figured out how to deal with pesky snakes.
