Every once in a while I see a Hawk or an Owl flying through the air with a snake. Those owls are pretty effective predators. Grabbing kittens and small dogs is child’s play.
I have a family of Harris’s Hawks that are living in my yard. Bonus! They eat rattlesnakes. Haven’t seen one since they moved in.
A few years back when we were down in south Texas, my wife noted all the roadrunners around a friend’s yard and mentioned that they killed and ate baby rattlesnakes.
But when she told him he probably didn’t have to worry about rattlesnakes in his yard, he looked at her and said very seriously, “Yes, but they can’t get’em all.”
