For the past eight years, Jennifer Arnold and Stephen Oswald, professors from Penn State University, have been studying the Common Tern population on Gull Island, in Presqu'ile Provincial Park. This study attempts to determine why the population is dwindling and what measures need to be taken to enhance population numbers.  They have produced a video for the Friends of Presqu'ile explaining what successful measures they have taken leading to an increase in the population.  The Friends have provided financial support for this project.  If you would like to view their video please click on the following youtube link:   https://www.youtube.com/watch?v=Z_93h9agDvw&feature=youtu.be.
