The pileated woodpecker, also called a logcock, is reclusive. It is more often heard than seen. It has a wingspan of 30 inches and flies with a swooping, undulating motion. Its size and red topknot make identification easy. It nests in holes in large trees and is a beneficial bird because it eats carpenter ants, caterpillars, cockroaches, and other wood-destroying insects but rarely eats berries.
