This is a very special bluebird house handmade for me by Dr. Dean Rust, President of the Bluebird Society of Pennsylvania. This is a Troyer-Slot Box, named after Andrew Troyer, the Amish man who designed it. This house has an added skylight which is thought to discourage English Sparrows.
It was actually raining when I captured this image. It seemed like this hummingbird was waiting for the rain to hit its tongue, similar to what a child might do.
