The red-headed woodpecker relies on habitat with dead and dying trees for a couple of reasons. First of they are cavity nesters, they typically nest in dead trees that have little bark left on them. They are very territorial when breeding and will often destroy the nests and eggs of other birds, especially other cavity nesters. Red-heads are also one of only four types of woodpecker that are known to cache food. They usually cache food, (seeds, acorns, or insects) in cracks and crevices in the dead wood. Unlike the other woodpeckers that cache food the red-head will sometimes cover their cache with bark. So it is important to leave enough dead trees in the forest because by removing all of them we may inadvertently remove another species of birds from our planet such as the red-headed woodpecker.
