Bluebirds on the deck

I've just spent a good few minutes watching 5 Bluebirds on the Upper Deck. I have a hanging feeder from the Hickory tree that looks like a little house with clear lexan sides Each end has a Bluebird size hole which excludes the Starling Vultures who steal all the food. Part of the roof folds up allowing the addition of lots of dried mealworms and chopped cranberries. The Bluebirds are in and out all the time so I'm happy. Heres a picture from earlier this year.
