Megan Murgatroyd equipping an eagle with a UvA-BiTS tag used to collect the data presented in our paper. These tags collect high-resolution GPS locations, altitude and three-axis acceleration data. They are able to collect large volumes of data because information is downloaded to a ground station rather than being transmitted via satellite. (© Gareth Tate)
