Golden Eagle Project Maps – Updated October 2016

This map displays the density of use of habitat of six Catskill region golden eagles that were present during the winter and spring. Individual GPS data points can be seen where eagles were traveling. The darker areas are where eagles persisted. The triangles are sites where the eagles were caught and then released in 2014 and 2016.

These GPS data collected from the six Catskill eagles were analyzed to understand where eagles were regularly found. From the duration of use estimates, data were grouped into two categories, the home range, where 95% of all GPS points were observed, and the core range, where 50% of all GPS points were observed. The birds’ home range totals 239.24 square miles, 92% of which is forested. The core range area is 12.21 square miles, composing only 5% of the larger home range.

Why Birds Matter...

Birds are important because of the role they play in the natural world as pollinators and seed disbursers, assisting with the balance of nature by eating insects. They also clean up things that would go unattended otherwise. Birds are important TO ME because of the kinship that I feel with another living species, and the joy that they bring to me year around. Encountering spring migrants feels brand new every time! I feel responsibility for their well-being and take care not to disturb their nesting with unnecessary sounds, disturbance or habitat destruction. I respect the incredible work they do to bring about future generations.

Birds have always been an early warning system for our environment–the “canary in the coal mine.” It was the decline in bird species high on the food chain that tipped us off to the dangers of DDT and other chemicals. More recently, high altitude and high latitude birds are demonstrating the first definitive effects of global change. If science had been more advanced in the 1800s, the extinction of the Passenger Pigeon could have served as a warning about habitat destruction. This not just about protecting the birds–although that is a worthy goal–but all of these threats will ultimately reach the human race.

In addition to being indicators for environmental health, birds matter because they allow people all over the world to enjoy and appreciate nature. Caring about birds often leads to caring about their habitats and creates a stewardship ethic to protect our natural resources. Birds connect communities.
