”A male reindeer has one goal in life – having his own harem. Powerful males are able to gather 30–50 females to form one. Defending the harem and keeping the females in it satisﬁ ed is hard work.
Although mating with a female takes only 15 seconds, it is nevertheless a strenuous endeavour for males: after the act, they will stop eating altogether for a couple of weeks and consequently lose a ﬁ fth of their body weight. For females, being in heat is not as demanding: their appetite remains mostly unaffected.”
