One of the fairly anonymous but very useful residents of my backyard is an adult Texas Garter Snake. The snake is seldom seen. I discovered him earlier this year when I was standing near one of my flower beds and looked down to see this seemingly large and very well-fed snake about to slither its way past my feet.
Was I startled? You bet! But I managed to stand my ground without jumping out of my skin and indeed the snake did slither past and continued on toward the woodpile at the back of the garden. I suspect that is where he spends most of his time.
