Tracking Common Ravens has shown them to be incredibly competent when it comes to navigation, responding to sounds and remembering sources of food. In Yellowstone, the Common Ravens are where visitors stop. They know how to open hatches on snowmobiles to access visitors’ food and how to enter a snow coach when the windows are down just enough to find any tidbits left in the open. This Raven was perched atop a rock with its mate when we stopped to watch as it played with what appeared to be a partial wing of some type of bird. This Raven has leg bands and a GPS tracking device affixed to its back. The study of Ravens in Yellowstone and surrounding areas is conducted by a research team that uses an App that lets you track the locations of the Ravens based on the color and leg position of their bands. When I searched for this bird based on its leg bands on the Animal Tracker App, it appears to be #7645, white over dark blue on left leg, green over silver on right leg. What I found interesting is that according to the App, this bird has not been tracked or documented recently and it was last documented about halfway between Livingston and Gardiner, MT three years ago. That may mean I misidentified the colors of the bands, that the GPS tracking device has died, or that reporting is spotty or inconsistent. We spotted it about 60 miles south of where it was last documented, now inside Yellowstone National Park. Their research shows that Ravens travel long distances so that is not an unusual occurrence.
