Brad, If you are around long enough and pay attention, you see some amazing things. I saw a bass come up out of the water in a vertical leap, go up in the air about 3 ft and take a small bird off of a limb on a dead tree out in a lake. I was about 10 feet away in a boat. I accidently caught a bulfrog while fly fishing. I guess frogs aren't as discriminating as fish. I saw a heron beside the road in San Diego swallowing a really large rat. Of course it is no surprise to fishermen that bass take ducklings as well as bullfrogs.
My aunt the biology teacher used to go bullfrog hunting with me. Most often I used a .22 rifle with short hollowpoints. She and my mom were cleaning a mess of frogs, maybe about 20, but were curious regarding some of the frogs distended bellies so they cut them open and had a look. They had been eating SNAKES, lots of snakes, about a foot long. Some were in good shape and some nearly digested and all stages in between. They both were so turned off that you could just say frog to either of them for the next week or so and they would get woozy.
Bet you thought I wasn't getting back to the SNAKE topic, ha ha.
