Early-successional, scrub-shrub habitats have been recently declining in the northeastern United States due to fire suppression, silviculture, and development. Pitch pine-scrub oak (PPSO) barrens and utility right-of-ways represent two habitats that are actively managed as early-successional habitat and appear to provide habitat for declining prairie warblers (Dendroica discolor) and other shrubland bird specialists.
The objectives of the study are to assess current habitat management and provide detailed information on the ecology and conservation of scrub-shrub birds in managed PPSO barrens and utility rights-of-way. Our focus will primarily be on prairie warblers, a high priority bird species in the northeast. We will be examining the effects of management on prairie warbler abundance, age composition, dispersal, and reproductive success in different habitats. We will also be examining habitat characteristics and other factors affecting nest success and nest-site selection of prairie warblers.
We are also beginning new research on prairie warblers in their non-breeding habitat in the Caribbean. Migratory bird populations are dependent on numerous sites along their migration routes, and understanding habitat quality in both the non-breeding and breeding habitats is crucial to conserving migratory bird populations. We will investigate prairie warbler territoriality and habitat use on the wintering grounds, as well as attempt to examine carry-over effects between non-breeding and breeding habitats using stable isotope analysis.
