Older male Einstein was first collared on the 15th March 2018 and weighed 45.35kg. His first data download surprised the research team when it showed him walking across most of the Okonjima Nature Reserve, showing typical ‘nomadic’ behaviour; a brown hyaena spatial tactic in which an individual does not belong to a clan, but mates with any receptive female they come into contact with. On the night he was darted, Einstein raced towards the bait the research team had put out and was eating the bait before the dart was even loaded. Since being collared, Einstein has turned up uninvited at many different bait sites, consuming all the bait himself, often causing the research team to abandon the night’s darting efforts. Being nomadic he may be found anywhere within the reserve and unfortunately often gets into fights with clan males who do not appreciate his presence within their territory.
