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.



Todd Jones, Ph.D.

Assistant Research Biologist, Conservation of Military Landscapes

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

Hannah graduated with a BS in Biology from SUNY New Paltz in 2015. She traveled the country for several years working on a variety of projects focused on both migratory and resident birds and their habitats. In 2022 she joined Archbold as a seasonal Florida Scrub-Jay research assistant at Avon Park Air Force Range. In her current role she continues to monitor the Florida Scrub-Jay population at the range, and also leads fieldwork to understand the interactive effects of fire, invasive species, and grazing on threatened and endangered birds.

Hannah Miller, B.S.

Liz earned a Bachelor's of Science from the University of Delaware and a Master's of Science from Youngstown State University. She spent several years banding avian migrants with Powdermill Avian Research Center before moving to Hawai'i to work with endangered forest birds. In 2021 she joined Archbold Biological Station and is the Florida Grasshopper Sparrow Biologist at Avon Park Air Force Range.

Elizabeth Abraham, M.S.

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.

Program Information

Military lands are home to more Endangered species than National Parks. Working within the Avon Park Air Force Range Sentinel Landscape, we combine research, demographic monitoring, and applied conservation to improve habitat and population management for Threatened and Endangered species including the Florida Grasshopper Sparrow, Florida Scrub-Jay, and Red-cockaded Woodpecker.
