Summer advancing, the hot weather fades. The first storms open their floodgates to revive the meadows. The female bison begin to stir. The mating season is soon here. By mid-August, early and non-lactating females enter heat. They are joined by the males who offer their service with a delicacy that could inspire some!
The male bison immediately spot the behavioral change of the females. He must then accurately assess the hormonal status of his “darling”. For this, he has an infallible detection organ, located just behind the palate, Jacobson’s organ. This is why he regularly smells the genital area of the female and, like an oenologist, he sucks by mouth pheromones emitted by the female.
If he thinks it is the right time for the mating , the male spends all his time with the female, accompanying her everywhere, sometimes for several days. Until the beauty accepts his advances.
