Regional Model to Help With Eastern Whip-Poor-Will Management
Eastern Whip-poor-wills are thought to be declining, potentially from habitat loss, pesticide use, and predation. To better understand their population status, researchers from West Virginia University and the USGS used nighttime road surveys in the Central Appalachians and occupancy models to study habitat associations and distribution of Eastern Whip-poor-wills. The best model for predicting occupancy was one that focused at a radius of about 1600 meters, or 2.5 acres. At this scale, Eastern Whip-poor-wills most frequently occupied areas lower in elevation and characterized by forested, herbaceous, and wetland habitats in contrast to high-elevation conifer forests. Detection rates were positively correlated with moon visibility and negatively correlated with noise. Survey results were used to generate a regional model to predict distributions of Eastern Whip-poor-wills within a national forest that can be used as a framework for future management. The authors note that successional clearings in forested habitats may be contributing to ongoing declines of Eastern Whip-poor-wills.
