Pileated Woodpeckers are our favorite woodpecker visitors to our winter feeder. Numbers of this crown-sized species depend on the presence of large, dead or deteriorating, trees. The birds use these trees for nesting and roosting. The woodpeckers suffer when forests are clearcut or if older trees are removed. Pairs defend their territory all year. Individuals do not abandon territories even if mates die (Bull and Jackson 2011).
