摘要

We investigated the relationship between red-cockaded woodpecker (Picoides borealis) reproductive successand microhabitat characteristics in a southeastern loblolly (Pinus taeda) and shortleaf (P. echinata) pine forest. From 1997to 1999, we recorded reproductive success parameters of 41 red-cockaded woodpecker groups at the Bienville NationalForest, Mississippi. Microhabitat characteristics were measured for each group during the nesting season. Logistic regressionidentified understory vegetation height and small nesting season home range size as predictors of red-cockadedwoodpecker nest attempts. Linear regression models identified several variables as predictors of red-cockaded woodpeckerreproductive success including group density, reduced hardwood component, small nesting season home rangesize, and shorter foraging distances. Red-cockaded woodpecker reproductive success was correlated with habitat and behavioralcharacteristics that emphasize high quality habitat. By providing high quality foraging habitat during the nestingseason, red-cockaded woodpeckers can successfully reproduce within small home ranges.
