I love it when I stumble upon little video gems of wildlife in our National Parks. Here a pair of western diamond back rattlesnakes are captured fighting for dominance in the Saguaro National Park, something that most visitors to the park are not likely to see.

Are you sure they’re fighting? Looks to me like they might be mating…
I had the same initial thought, but went with the description with the video since they said that they showed it to park rangers.
