If you have bluebird houses in Minnesota or Wisconsin, or anywhere where temperatures are cold right now, please don't check your houses until temperatures rise again. Tree Swallows who arrived early this year are having lots of problems, and some are piling into bluebird houses for warmth. When we check on them, they get scared and leave, and when they're already stressed for calories and warmth, that can be disastrous.
