Biologist Adrian A Bishop uses high-tech equipment to track elusive birds like the Grand Duke owl, known as lenosat, using a signaling device. The device, monitored via satellite and Internet, confirms the owl's well-being. At the Natural History Museum in Freiburg, a snowy owl demonstrates the device, which tracks location, body temperature, and heart rate. Despite its cost, the device is crucial for understanding snowy owls' breeding habits and migration. It also highlights dangers like electricity pylons, allowing authorities to take preventive measures. Researchers hope to learn more about the effects of late winters on bird behavior.
