Peek a boo, I see you is what this bird may be playing. Its mate was nearby.
More likely though this bluebird may have been checking its surroundings to see if its safe outside. They may be a bit cautious but are definitely very protective of nest and young. We put this birdhouse up towards end of summer and shortly afterwards it became occupied.
Here in Northeast Tennessee the Blue bird is a common, year round resident.
