Organization: Maryland - National Capital Park and Planning Commission

Topic and Title: Ospreys on the Patuxent

Brief Description of Presentation/Brief Bio and Picture:

Join us to learn about Ospreys, the often-seen “fish hawk” of local rivers and the Chesapeake Bay, with. Kearns will discuss Osprey biology, his banding program with the public, re-introduction efforts, and how this once-imperiled bird became a conservation success story. Greg Kearns is a Senior Park Naturalist for the Maryland-National Capital Park and Planning Commission (MNCPPC) at the Patuxent River Park in Prince George’s County, Md.

He has worked for MNCPPC on the Patuxent River for over 38 years and is an expert on wetland ecology of the Chesapeake Bay, a licensed bird bander and a renowned authority on Osprey (Pandion haliaetus) and the Sora rail (Porzana carolina).


During Greg’s career at Patuxent River Park, he has spearheaded an osprey nest platform and banding program that spans a good portion of the tidal Patuxent River.  Greg and his interns have installed and maintained over 100 osprey nest platforms along 25 miles of river and banded over 5000 adult and juvenile Ospreys.  Countless volunteers and staff from DNR and other organizations have experienced Ospreys up close during the summer banding schedule with the program being so popular space fills up well in advance.  Greg not only does the technical monitoring work but makes it accessible to the public through unique educational opportunities. Greg was named Conservationist of the Year by the Maryland Dept. of Natural Resources in 2006 for his work on Soras and restoration of the wild rice marshes at Jug Bay, Md. and was awarded the National Wetlands Conservation award in 2017 from the Environmental Law Institute.

This work dovetails nicely with the wetland restoration, water quality improvement the rice provides for the fish and other organisms, and the Osprey’s role in this important ecosystem.
