Just doing a little calculation here. If deer are the primary prey of BFs, as is claimed above and there are 10,000 BFs in North America, the toll they must take on deer herds must be enormous. The usual statistic is that a mountain lion must kill one deer a week to survive. Now a BF must weigh at least 4X to 5X a mountain lion, if most estimates of size are correct. Let's be conservative, though, and estimate that a BF would need to kill and eat only three deer a week. If the 10,000 estimate is correct, then that would mean that BFs are killing more than 1,500,000 deer annually. You'd think wildlife managers would take some notice of the terrible toll these creatures are taking on our deer herds!
