I was at a bird sanctuary early one morning and happened to see a Great Blue Heron find and eat a large snake. I was amazed at how quickly the whole the process took place.
The heron was looking around in the grass and grabbed hold of the snake. He (the heron) tossed it around for just a few seconds, I think to stun or kill it. Then he swallowed it head first.
I thought it would take a bit of time for the bird to completely consume the snake, so I walked around the top of the shoreline to get a different angle.
It didn’t
take me more than two minutes to change positions. In that time the snake was pretty much gone down the heron’s throat.
FOG Sez: I think I’ll stick to a nice crunchy bowl of cereal for breakfast.
