Although this presentation ostensibly describes recent findings in Great Egret energetics, movement patterns, and habitat selection, an important backdrop to this story is about technology and science. Specifically, how evolving technologies in remote sensing have enabled our long-term studies on wading birds to address questions that until recently could not be asked. Our studies of wading birds in the field began with observations of unknown birds. We adopted VSH-based radio-telemetry about 10 years ago and were able to follow known individuals, whose local activity patterns could then be better understood. This technology has several drawbacks, including maximum distance for signal transmission, and when the birds departed after the breeding season, we were not able to obtain additional data. Currently, we deploy GPS units on Great Egrets, which has enabled us to follow birds across vast distances and throughout the year. For example, one bird has migrated across the Gulf of Mexico for the past three years.

Dr. Alan Maccarone earned his Ph. D. from Rutgers – The State University of New Jersey. He has been a Professor of Biology at Friends University since 1998 where he previously held the positions of Director of Environmental Studies for the Graduate Program and Director of Zoo Science for the Undergraduate program.
