Chickadee (revisited)

This used to be a bird feeder - soon after the squirrels chewed off the perches, the chickadees started using it as a nest box. They've set up house the last 4 years or so, but we can't really determine their success rate, other than the year they were vandalized. Fingers crossed for a good season and that I'm there to see the new generation take to the skies.
