Habitat Requirements of the Pileated Woodpecker in Northeastern Oregon
Nesting, feeding, and territorial activities of the pileated woodpecker (Dryocopus pileatus L.) were observed in the spring and summer of 1973 and 1974 in northeastern Oregon. The 13 nests found in a 28,000-acre area were in ponderosa pine (Pinus ponderosa Laws.) and western larch (Larix occidentalis Nutt.) snags greater than 23 inches in d.b.h. Pileated woodpeckers fed primarily in dead wood in snags, logs, and naturally created stumps. Both nest trees and feeding sites were in concentrations of snags and in the most dense forest types. Minimum nesting territories were estimated at 320 acres.
