Abstract

Methods of locating pileated woodpeckers (Dryocopus pileatus) are described, including imitating pileated woodpecker vocalizations, identifying nest and roost trees, and finding foraging signs. Populations of pileated woodpeckers can be monitored by using (1) density of breeding pairs, (2) reproduction, and (3) presence or absence of birds. The size of area being monitored, the amount of resources available for the work, and the amount of information desired determine which monitoring method is appropriate.
