Nestbox with swallow and snake.
The box has a well made baffle on the post, just below where the branch touches it.
This female was one of 5 or 6 swallows excitedly circling the box seconds before this photo was taken. The dark area on the face of the box alongside the snake is the bird's right wing.
This female bird is one of the small minority of birds overall that survive fledging and migration. Shame on us for allowing this to happen to her.
