Wife came in from the garden today. We have bluebird houses on poles and about 6 adults were very agitated near one house. On close inspection a good sized fox snake got past the baffle and had mostly squeezed into the house through the air vent.

So I grabbed the tail and yanked. About a another 3 1/2 feet of snake came out which is about as big as they get around here. That air vent was pretty skinny too so the snake got a good lymphatic massage. All quiet since, no word on birds, house or the snake.

Fox snakes are good on small rodents so I would not want to harm one, but forced to take sides I'll choose the bluebirds.
