Dr. Jones is a conservation biologist and evolutionary ecologist leading the Conservation Science of Military Landscapes program at Archbold Biological Station, with research focusing on the monitoring, management, and conservation of threatened, endangered, and at-risk bird species across the Avon Park Air Force Range Sentinel Landscape. Prior to joining Archbold in 2024, Dr. Jones completed his B.S. at The Ohio State University, his M.S. and Ph.D. at the University of Illinois Urbana-Champaign, and postdocs at Texas A&M University-San Antonio and the Smithsonian Migratory Bird Center. Dr. Jones interests include conservation biology as well as avian behavioral and evolutionary ecology, breeding biology, and life history theory, with much of his past work examining the post-fledging ecology of birds.

Greg grew up in central Florida and fell in love with the ecosystems of the region. He attended the University of Central Florida and majored in Environmental Studies. He started working for Archbold at  the Avon Park Air Force Range in 2013. He has worked extensively with the Florida Grasshopper Sparrow project, and now leads Red-cockaded Woodpecker monitoring and management at the range. In his free time, he enjoys exploring Florida’s natural areas and learning to identify species from other taxonomic groups.

Research Assistant IV

Mary is from St. Cloud and has loved central Florida's wildlife for as long as she can remember. She moved to the mountains of North Carolina for undergrad, where she attended Lees-McRae college. While there, she double majored in Psychology and Wildlife Biology with a concentration in Wildlife Rehabilitation, and minored in Art and Design.  Mary worked for a season with Florida Grasshopper Sparrows as a technician at Three Lakes WMA and absolutely fell in love with the sparrows. She moved to Kansas to attend Pittsburg State University for a master's in biology, before returning to Florida, where she is back with the sparrows as site leader at Deluca Preserve. When she isn't at DeLuca, you can usually find Mary out birding with her husband, working on creative projects, or curled up with a book and her cat.

Jesse earned a Bachelor's of Science from the University of Wisconsin - Stevens Point and a Master's of Science from State University of New York at Binghamton.  He has been working with birds since 2015, including two seasonal technician positions with Archbold at Avon Park Air Force Range.  He worked as a Red-cockaded Woodpecker Biologist for FWC in 2024 before returning to Archbold and the Avon Park Air Force Range as a Florida Grasshopper Sparrow Biologist.

Research Assitant

Archbold scientists have assisted state and federal collaborators with monitoring and management of the Florida Grasshopper Sparrow since the early 2000s. As part of the species' working group, Archbold seeks to gain a greater understanding of associations between demograhics, management, and cattle farming to aid in the recorvery and conservation of the species.
