The Kingfisher at the top was sat minding its own business when the other bird flew at it. They locked together and were thrashing about for about a minute. They then separated and sat about 3 feet away from each other gesturing and bobbing about. At no time did they seem to take their eyes off each other. After 90 minutes they were still there. I got bored and went home. The outcome may never be known.
