Bob Aeppli, Field Biologist, Purple Martin Conservation Association.
Bob Aeppli is currently a Field Biologist for the PMCA and has been with them since 2009. He received a B.S. from Penn State in Biology/Ecology and is currently working an M.S. in Environmental Health and Engineering. Bob's work with Purple Martin migration using Geolocators and GPS units has lead him to want to understand how things are effecting their migration. As he has progressed through his masters program his understanding and concern of the changing environment has grown. With current long term declines in Martin populations, mainly in the Northern parts of their range it has been thought that climate change may at least partially be to blame. Seeing how much these changes in climate are affecting the populations with help those at the PMCA to better advise and further conserve this species that is so dependent on man to survive. The project using BPP records will investigate the changes in Spring arrival times and then see how they correlate with fluctuating long term weather patterns as well as specific weather events. Data such as changes in temperature (Max high and low temp, avg. temp....), as well as precipitation data.
Ali Arab, Ph.D. Assistant Professor, Department of Mathematics, Georgetown University.
Ali Arab’s research goal is to study spatial and temporal trends in the migration patterns of birds based on the historical records at NABPP. In particular, he is interested in correlating these spatial and temporal trends with climate indices and other environmental variables (such as severe climate events) to provide a more detailed analysis of the potential impacts of climate change on bird migration patterns over the past century for which data is available. Dr. Arab is currently working on the New York bird migration paper with the NABPP as well as on an upcoming paper with Jessica Zelt on bias in citizen science data.
Jason R. Courter, Ph.D. Assistant Professor of Biology, Malone University.
Jason Courter’s area of interest is using novel temperature approaches to monitor climate change and optimize bird conservation. In 2011, Dr. Courter gave a PowerPoint presentation at the Ecological Society of America Annual Meeting in Austin, Texas, on Assessing effects of climate change on bird phenology at broad temporal and spatial scales. In 2012, Dr. Courter published his first paper using data from the NABPP on weekend bias. In 2013, he published two additional papers using NABPP data on spring arrivals for several migratory species and Ruby-throated hummingbird migration.
Steven Hilburger, USGS Biologist.
Master’s thesis, George Mason University. “Spring Migration Phenology of Four North American Insectivorous Bird Species in Relation to Climate Change.” The thesis describes the relationship between spring migration of four bird species, and eight environmental variables that could influence migration.
John Sauer, USGS Research Wildlife Biologist.
Together with Agathe Dupontiel, former BPP Intern, John Sauer completed statistical analysis of Barn Swallows using data from BPP migration records to explore its quality and characteristics. Analysis was then done using more specific information such as the cycle of arrival dates over time, the association of spring temperatures and the NAOI and SOI indexes. All data on Barn Swallow used for analysis were documented from 1895 to 1968.
The purpose for our internships is to help gain work experience while at the same time receiving guidance in a scientific study. Students are selected from the Eleanor Roosevelt High School where a study is required by all students graduating with the Science and Technology Department.
