The foraging behavior of six sympatric woodpecker species was studied between March 18 and April 24, 1975, in an oak-hickory woodland in Iowa City, Iowa. The six species of woodpeckers did not differ significantly in the parameter of mean foraging height, but did forage on different mean limb diameters. Other differences in foraging behavior noted between species were dead/live tree selection, sap utilization, and ground foraging. Significant differences in foraging behavior were also recorded between sexes of downy woodpeckers. Males tended to forage higher in trees and on smaller limbs than conspecific females.
