To determine structural features associated with successful reproduction in this species, I related success or failure of a nest to habitat surrounding the nest site. Within a territory, habitat surrounding successful nests was significantly more likely to contain larger than average trees and a dense upper canopy, while unsuccessful nests were associated with a dense understory. Selective cutting at one of the sites has not significantly altered the forest structure, or Cerulean Warbler reproductive success, relative to the two unmanaged sites. Continued monitoring of the population at this site is required to further determine management effects on this species, however it is possible that certain forest management activities may be compatible with the conservation of Cerulean Warblers. This study furthers the recommendations of earlier work suggesting Cerulean Warblers require large tracts of mature forest by identifying tree size and relative canopy density as specific features of a mature forest related to successful reproduction.
