Fall movements of Red-headed Woodpeckers in South Carolina
Fall migration of Red-headed Woodpeckers (Melanerpes erythrocephalus) can be erratic, with departure rates, directions, and distances varying among populations and individuals. We report fall migration departure dates, rates, and routes, and the size of fall home ranges of 62 radio-tagged Red-headed Woodpeckers in western South Carolina. Rates of fall migration differed among years; all radio-t...
متن کاملHeart Rot and Cavity Tree Selection by Red-cockaded Woodpeckers
Previous studies implied that decayed heartwood was important to cavity tree selection by redcockaded woodpeckers (Picoides borealfs), but the results were inconcIusive because they either lacked a control or were limited to 1 age class of trees. We compared the incidence of heart rot in loblolly and longleaf pines (Pinus taeda and P. palust7.fs) undergoing cavity excavation to the incidence of...
متن کاملCharacteristics That Contribute to Nest Success of Endangered Red-headed Woodpeckers (melanerpes Erythrocephalus)
Red-headed Woodpeckers (Melanerpes erythrocephalus) are endangered because they have experienced population declines of up to 80% in the past 40 years. The purpose of this study was to identify key habitat and nest-tree characteristics that contribute to successful breeding at Cedar Creek Ecosystem Science Reserve in East Bethel, Minnesota, with the goal of making recommendations to recovery pr...
متن کاملPopulation Ecology Factors Affecting Breeding Season Survival of Red-Headed Woodpeckers in South Carolina
Red-headed woodpecker (Melanerpes erythrocephalus) populations have declined in the United States and Canada over the past 40 years. However, few demographic studies have been published on the species and none have addressed adult survival. During 2006–2007, we estimated survival probabilities of 80 radio-tagged red-headed woodpeckers during the breeding season in mature loblolly pine (Pinus ta...
متن کاملNest-Site Characteristics of Red-bellied and Red-headed Woodpeckers and Northern Flickers in East-Central Ohio
In order to understand more clearly what factors limit the reproductive success of primary cavity-nesting birds, it is important to examine and compare the nest-site characteristics of sympatric species in a variety of forest and woodland habitats. To add to the data already available on various woodpecker species in eastern and central North America, several nest-site and habitat characteristi...
