Sapsucker sap wells provide a food source for migrating hummingbirds. They drill wells and eat sap from 246 native tree species. The young learn sapsucking by observing their parents once they leave the nest. Male and female sapsuckers perform drumming duets to strengthen their courtship bond. Ivory-billed Woodpecker Campephilus principalis Extirpation means no longer living in a certain location or place.
Extinction is forever.
Extinct animals or plants no longer live anywhere. Until recently, the ivory-billed woodpecker was believed to be extinct. Although this sleek and secretive giant no longer graces the forested swamps of the southeastern U.S., a few individuals may have managed to hang on in the mountains of eastern Cuba. In the U.S., extensive logging of bottomland and virgin cypress forests during the late 1800s and early 1900s led to the demise of the ivory-billed woodpecker, which once lived in southeastern Missouri. The species decline was especially swift because a single breeding pair needs about three square miles of undisturbed forest for its territory.
