Play by Peary caribou calves before, during, and after helicopter harassment
We observed 93 bouts of play behaviour by Peary caribou (Rangifer tarandus pearyi) calves on northeastern Prince of Wales Island, Northwest Territories (N.W.T.), between 23 June and 16 August 1977. Play consisted of 58 contagious, 20 exploratory, 13 agonistic, and 2 sexual bouts. Calves engaged in 3...
