Abstract

Hairy (Dryobates villosus) and downy (Dryobates pubescens) woodpeckers occur in high densities in residential areas of the eastern United States. In many areas of their range, they cause damage to wooden structures through foraging, excavation of nesting cavities, and drumming behaviors, causing requests for allowable take permits. Both species hold year‐round territories, which could make them vulnerable to local extirpation with excess take. To meet the requirements of the Migratory Bird Treaty act, the United States Fish and Wildlife Service (USFWS) requested scientifically informed evaluation of take to minimize population effects as part of its approach to reduce human–wildlife conflict. We used a prescribed take approach, which uses data from population, demographic, and management parameter estimates to determine the allowable take from Louisiana to Minnesota and all states east. Furthermore, we used 2 different methods of estimating growth rates to control for demographic uncertainties. The resulting estimates provide take at the state and USFWS regional scales to improve stakeholder choices when setting allowable take. Current authorized take (2016–2018) is below the take that could be sustained by current populations, and current rates of take are not likely to cause population‐level effects. These results were largely consistent across methodologies for calculating the rate of growth for both species. Take still needs to be managed to prevent local extirpation of these resident species. Allowable take estimates should be periodically updated to reflect changing management and population needs for both species. [ABSTRACT FROM AUTHOR]
