Example text

It does seem odd that Alan saw two aggressive encounters per cow per hour if these cows weren’t competing for scarce resources. Yet it’s typical of a dominance system that the dominant individuals launch a steady stream of preemptive bullyings—sort of like those “Don’t even think about it” admonitions. But buffalo cow society was very different on Catalina Island. Once severely overgrazed, Catalina, despite decades of restoration, offered slim pickings to the 400 head of bison grazing there; and that raised the stakes for the cows.

Cows seem to be more receptive to older bulls, and that makes sense; winters, battles, disease, and predators have tested them. We don’t yet know what cues besides age the cow may use in making her choice. Could all that bellowing make a difference as to which bull is standing beside her when she stops running? Could it work like some birdsongs or frog croaks—a clue to the female about who might be a bet- 17 R E L AT I O N S H I P S ter mate? The bulls don’t seem to be sending a signal—they appear only to bellow to other bulls.

When Jerry Wolff compared the ranks of the bulls left to those approached, he found the cows were usually approaching a higher ranking bull. That’s one of the forms of choice a cow has, and it makes sense for her to be as choosy as she can manage to be. She will have just one descendant in the next year, and only half its genes will be hers; she should be as fussy as possible about where the others come from. But the bulls usually severely limit the cows’ choice. On any given day there are fewer ready-to-breed cows than eager-tobreed bulls in a herd with a natural sex ratio—that is, nearly as many bulls as cows.
