| TREE SWALLOW RESEARCH BIBLIOGRAPHY Last Updated 9/30/2009. Recent additions noted by authors in red. Previously updated 11/12/2008. Our intention is to update this bibliography once or twice a year. Most articles listed feature Tree Swallows as the primary study species. Some utilize Tree Swallows as a comparison species or as one of a group of species being investigated. A few more general articles are included for their pertinence to issues in Tree Swallow research. A number of older, more anecdotal studies are also included, primarily ones whose authors helped pioneer the use of multi-box projects and foresaw their value in ornithological research. |
