Eastern Bluebirds (Sialia sialis) are secondary cavity-nesting species that are overcoming declines in their populations caused by habitat fragmentation and interspecific interactions with other native cavity nesting species, such as Tree Swallows (Tachycineta bicolor) and House Wrens (Troglodytes aedon), and invasive cavity-nesting species, such as the House Sparrow (Passer domesticus). House Sparrows and House Wrens will compete fiercely with the bluebirds for nest-boxes and often harm the adults and/or young in the process. Tree Swallows will usually live harmoniously with bluebirds as long as there are enough available nest-sites to choose from. During the breeding seasons (March through August) of 2003 and 2004, the effects of multiple factors, such as competitors (both native and invasive) and various nest-box characteristics, on nest-site selection and nesting success of Eastern Bluebirds were observed. A total of 191 nest-boxes erected within the boundaries of the Bath Nature Preserve, Bath, OH, and the Metro Parks serving Summit County were used. Selection of a nest-box by all competitors was determined by the nesting activity observed within the box. A bluebird nest with at least one nestling fledged was considered successful. Results and conclusions from this study were used to develop curricula for local Akron City Schools, and will lead to a more concrete understanding of which competitors and/or which nest-box characteristics influence the nest-site selection and nesting success of Eastern Bluebirds.
