Nesting attempts and success of Arctic-breeding geese can be derived with high precision from accelerometry and GPS-tracking

Sensors, such as accelerometers, in tracking devices allow for detailed bio-logging to understand animal behaviour, even in remote places where direct observation is difficult. To study breeding in birds remotely, one needs to understand how to recognise a breeding event from tracking data, and ideally validate this by direct observation. We tagged 49 adult female pink-footed geese ( Anser brachyrhynchus ) with transmitter neckbands in Finland...
