I have spent the past two days in the garden, trying to get some good video of this robin. Is he besotted with himself? He won't leave it alone. Is he just trying to understand? He does keep trying to fly through the mirror. Has he fallen in love with what he thinks is another robin? I have no idea how intelligent robins are. Has this psychologically damaged him for life? He's not there this morning.........perhaps he figured it out.
