I even managed to catch it on video. I like how once the heron finally gets it into its throat it takes several gulps of water to help wash it down - must be a bit squirmy still!!
The gartersnake isn't the only tasty treat I've seen a Great Blue Heron catch recently. Last week my sister and I watched as a (the same?) Great Blue Heron walked through the pasture across from my house and captured then swallowed a small mammal - possibly a meadow vole.
