2 Introduction to The Blubonnet Bird Monitoring Project The Bluebonnet Bird Monitoring Project (BBMP) is a collaborative effort between Louisiana State University s School of Renewable Natural Resources, The Recreation and Park Commission for the Parish of East Baton Rouge (BREC) and the Baton Rouge Audubon Society. Three goals guide activities at BBMP: to monitor and study bird populations at Bluebonnet Swamp and surrounding areas, to provide unique and exciting outreach to local children, and to provide training opportunities for local university students thereby preparing the next generation of ornithologists in Louisiana. Bluebonnet Swamp Bluebonnet Swamp is a 103-acre forest fragment surrounded by the urban landscape of Baton Rouge. Small isolated forest patches, such as Bluebonnet Swamp, may provide the resources necessary for resident and migrant birds to survive and successfully breed. Conversely, habitat fragments may not provide the food or shelter necessary to sustain healthy bird populations. To determine the value of Bluebonnet Swamp to birds we use contemporary censusing methodologies (bird banding and area searches) to estimate survival, population growth and community structure of migrant and resident birds species at the swamp.

3 Accomplishments Since March 2010, volunteer ornithologists and citizen scientists have continuously monitored birds at Bluebonnet Swamp resulting in approximately 2,000 individual bird captures. All data have been digitized and archived through the Landbird Monitoring Network of the Americas which uploads data to the Avian Knowledge Network and the Tree of Life. Analysis of our data has led to several scholarly manuscripts that have been published, are in press or are currently in review. Our manuscripts cover topics such as molt ecology, behavior and demography. In addition to scientific contributions, we partner with BREC to provide unparalleled environmental education to local children focused on ecology, ornithology and conservation. Since March 2010, we have taught over 200 children about bird conservation in Baton Rouge. Barred Owl eating Sharp-shinned Hawk. Photo from Johnson et al. (2012). Photo by John Hartgerink.

5 Volunteers and Funding Banders and our database manager, Sherri Utley, have donated thousands of volunteer hours. We have recieved funding from the Western Bird Banding Association Reseacrh Grant, Eastern Bird Banding Association Research Grant, Louisiana State Enviromental Research Grant, proceeds from the Peter Pyle Advanced Banding Workshop and in-kind equipment and overhead from BREC and LSU s School of Renewable Natural Resources.

Future Endeavors In the winter of we plan on increasing the breadth of our bird monitoring program by expanding our efforts to French Town, a BREC managed conservation area. The Bluebonnet Bird Monitoring Project has also acquired the necessary funds to purchase geolocators (data-loggers that are attached to migrating birds to estimate longitutde and latitude by the timing of sunrise and sunset), which will be used to study migratory connectivity; we plan on starting thegeolocator study in the Spring of Dan Mooney with Brownheaded Cowbird.
