Cerulean warbler population and breeding response to recent silviculture and influences of prey availability on avian nesting ecologyWagner, Jennifer R. 05 May 2012 (has links)
This study presents the results of a field study comparing the effects of two forest harvest methods on the Cerulean Warbler, a state-endangered songbird. Population
estimates and a breeding study produced no significant differences among groups, although the species was not attracted to forest openings and experienced decreased nest
success in treated sites. Additional study on prey influences showed strong correlations with timing of breeding and peak larval lepidopteran abundance, specifically on oak and hickory tree species. Data suggests that these trees are vital to increased probability of
nest success due to an increase in prey availability within territories. Further study is recommended to ascertain the long-term effects of forest harvest and the importance of
oak and hickory dominated landscapes to the persistence of this species. / Cerulean warbler population response and nesting success in forests with recent silviculture -- Avian nesting ecology and prey abundance using frass drop as an indicator. / Department of Biology
