I was recently entertained by a small bird who was having trouble communicating with his mate. The bird spent quite some time looking into the rear view mirror of the car from all possible angles and chattered away each time.
His frustration with the reluctance of the mate to respond was evident.
The performance was repeated some time later, obviously the creature was not easily discouraged! This pantomime took place in a car park in a woodland reserve, so I imagine there are a lot of frustrated Honey Eaters in this area!
