Our Osprey Tracking project is proving to be enthralling, fascinating, and occasionally anxiety-producing. For background information about the project and to continue to follow the fortunes of our Ospreys, go to http://www.nhnature.org/osprey_project/overview.html.
The lightweight (30g) transmitters are worn by the Ospreys like a backpack. Every three days, the transmitter uploads data to a satellite. Each upload includes an exact GPS location, altitude, direction, and speed of flight each hour during daylight hours. I can access that raw data, then plot the data in Google Earth, providing an incredibly detailed “over the shoulder” look at the movements of these birds that allows us to understand so much about migration that was previously unknown and learn about the threats they face.
We tagged three Ospreys in 2012 – Art, Jill and Chip. Here are their stories so far:
