Description: Oak (Quercus spp.) regeneration has declined drastically over the past century in eastern deciduous forests predominantly because of decreased disturbance (i.e., fire). Many forests are undergoing mesophication, a positive feedback system that occurs within closed-canopy systems wherein shade-tolerant, late successional, mesic species such as maples (Acer spp.) and American beech (Fagus grandifolia) outcompete fire-adapted oak. The Central Hardwood region is predicted to be the first major system to convert to climax succession. Numerous neotropical migrant populations have declined in this region. Oaks are a keystone species and provide many resources for forest birds; the ability of mesic species to provide similar resources is untested. To determine whether patches of distinct oak forest and mesic forest provide similar resources, we examined two nonexclusive habitat-selection hypotheses about avian abundance and distribution: (1) habitat heterogeneity and (2) availability and distribution of food resources. We predicted oak-dominated patches would provide greater heterogeneity and more food resources than mesic patches.
