Bird owners need to be cautious of those pesky snakes. I took this picture this morning to drive home my point. This is a three foot black snake Non-poisonous to us humans. But they do love small birds. This particular varment was trying to make it's way into my neighbors home through a window. There was a hole in the bottom of the window screen. Fortunately they weren't home and their windows were closed or else they would have had a visitor waiting on them upon their return.
