Albert, 20 years old, is the dominant male of the released group. He scared us at the beginning of the week when his collar sent a mortality signal. These signals as well as the GPS points are transmitted to a satellite by the Argos platform of his collar. All these information are processed and we can retrieve the GPS points on a web site that we check every day.
The next day all was fine so we believe that it was a collar malfunction, not a problem with Albert!
