Join us for a presentation on Animal Warning Systems in the Forest by UM wildlife biologist Erick Greene. Erick will share fascinating discoveries he and his students at UM have made about how animals communicate about danger. They have found that birds and other animals have remarkably specific alarm calls: for example, "snake on the ground," "flying hawk," "perched hawk", and so forth. It also turns out that animals understand the alarm calls of other species, so many animals in the woods are cooperating to produce a "distant early warning system." Anyone who has tried to walk quietly or hunt in the woods has likely been the subject of this communication network! Erick will explain how alarm calls work, and demonstrate the amazing infoscape that exists in our woods.
