This was really funny to watch though, after a while, I began to feel guilty for laughing at the poor little Blue tit because it was getting more and more agitated about that other Blue tit in the mirror.

Birds, of course, don’t understand the concept of a mirror or reflective surface, so think they are seeing another bird that has invaded their territory and try to chase it away.

In case you haven’t seen one of these mirrors before, they can be attached to a post opposite the entrance to someone’s driveway so they can more easily see approaching traffic when trying to exit their property.
