What do woodpeckers do with seeds?

Woodpeckers primarily feed on insects found in trees, but they also consume seeds, especially from various nuts and fruits. They use their strong beaks to drill into tree bark or other surfaces to access seeds or to create holes where they can store food for later. Some species, like the red-headed woodpecker, are known to cache seeds in crevices or bark for winter sustenance. Overall, seeds are an important part of their diet, particularly when insect availability is low.
