BETA - Bald Eagle Tracking Alliance
In our Lower Fraser Valley of British Columbia we believe that in addition to our 500 breeding pairs of bald eagles, we have over 35,000 eagles annually passing through: where do our 1000 breeders go after the young fledge and where do the other 34,000 eagles come from — and go to when they leave here? Hosting the world’s largest gathering of bald eagles, and probably having more large predators than anywhere else in the world, we are finally taking on the responsibility to find out more about them.
This BETA Project, in cooperation with Simon Fraser University, and in Phase 1 is a 10 year introduction to these eagle movements. As different age classes and geographically resident eagles get tagged we hope to formulate additional questions and plan fact based managements recommendations. Is the population still expanding or now declining? Since so many eagle are dying of pesticides and heavy metals can we determine where they are picking up these contaminants? And since electrocution remains the largest local killer of our eagles can we learn something about their local movements that would assist BC Hydro in where to place perches above the killing wires?
Trapping some of our local breeders and some of the thousands of migrants will be a start to our better understanding of the world’s largest gathering of bald eagles. Please support the BETA Project: follow an eagle on its annual journey. If you can contribute financially to the Project please do so. The HWF team has devoted a large portion of our consulting dollars to buying Trackers and our first grant application to Molson Breweries also resulted in a fine support grant. At about $5000.00 cost per Tracker we need your support.
This map is a dynamically generated map showing the flight paths of our currently tracked birds since the moment they first had the transmitter placed on them. As you can see, some prefer to stay local, some have ventured down to Oregon and up to Alaska so far.
