The appropriately named sapsuckers are highly specialized woodpeckers that use their sharp beaks to drill neat rows of small holes in the bark of trees. Then, with brush-tipped tongues, they lap up the sap that oozes out and eat the insects it attracts. They sometimes snatch insects in midair, as well, and occasionally feed on wild fruit. In typical woodpecker fashion, sapsuckers excavate nest holes in trees, often dead. Females incubate the eggs during the day, and males take over at night. Both parents share in feeding the young. Unlike other woodpeckers, the sapsuckers are strongly migratory: Yellow-bellied sapsuckers, for instance, travel thousands of miles when the seasons change.
