Foraging ecology of pileated woodpeckers in coastal forests of Washington

Article Abstract:

Study was conducted to study the food habits of pileated woodpeckers in coastal forests, evaluate the relative abundance of their primary prey, carpenter ants, related with logs and cut stamps, and determine the selection of forest structures and site features used by pileated woodpeckers for foraging. It was observed that carpenter ant was the main food item of pileated woodpeckers but in the breeding season, the primary food item were round-headed beetle larvae and dampwood termites, selection of foraging structures depended on the wood features and presence and abundance of arthropod prey affected the microsite conditions.

Predation of artificial nests in hardwood fragments enclosed by pine and agricultural habitats

Article Abstract:

The hypothesis that the depredation rate for bird nests in small hardwood forests would decrease if the degree of edge contrast with adjoining habitats were reduced was tested. Predation was found to be greater in shrub nests but did not differ between edge and interior nests between or within stand types. Nest predation by birds was not suspected in pine-enclosed stands, but 18% of the nests depredated in the agricultural-enclosed stands was attributed to birds.
