Show Summary Details


Social life comes down to managing — one could almost say juggling — relationships. For bison, the most complex relationships play out during the intense though brief breeding season. Attraction, rejection, acceptance, competition, and cooperation within and between the sexes create vital, compelling, generally short-lived, and shifting relationships. This chapter describes these entangled relationships. The prolonged forewarnings, the reluctance to fight, and the generosity to losers are neither the last noble vestiges of chivalry in our time nor nature's way of exhorting humans to live on a higher ethical plane. Rather, they are carefully balanced behavioral adjustments to the social and ecological circumstances in which the competition between bulls evolved. The trade-offs that natural selection selects usually bring all the costs and benefits to bear and therefore favor very different strategies in different kinds of animals.
