This is what a bison thinks about 90 degree September days:
A 300mm lens at 10 feet might be a little too much lens for a bellowing buffalo.
Some of the cows appeared to be entering estrus as the bulls were cordoning off single females when we visited back in August.
There were good numbers of calves around too.
One last pic of the "American Serengeti," hopefully it heralds a few more pics in the near future
