Great Blue Heron

We've had a large avian visitor several days in a row now. He (or perhaps she) lands in the large expanse of side yard we idealistically call the West Meadow (I hope to plant a field of wildflowers there one of these days). He's quite gorgeous, and he just sits there or walks slowly through the tall grass. Once, I saw him stretch low and then swoop quickly at something, so we wonder if he's hunting. He's welcome to some of the mice around here!
