I saw an animal that I thought was a squirrel near our small pond but when I looked closely I realized it was a mink.
We have had them in the yard before but not hunting in the pond.
It dove into the pond which is not much bigger than the mink. It came out with a frog which it left on the grass. It went back several more times and caught more frogs.
I went outside to get better photos and it seemed to scent me and started taking his prizes away.
Minks are a voracious predator, and they eat a wide variety of prey and will store any surplus to eat later.
