Really neat interaction showing off their role as secondary pollinators. Altogether I saw two rattlesnakes and a bullsnake in the span of an hour. This was at the edge of a large black-tailed prairie dog colony in the foothills of the Rockies. I missed the strike by a couple minutes but you can see how big the fangs are in this photo. Both are fairly large adults.
Maybe the other prairie dog was their colony's (is that what their burrow hole things are called?) version of Thatcher?
