By the sounds of it, they probably were fighting. I was standing about 20ft away and they completely ignored me as they swirled around each other like a mini whirlwind to about 30ft high and then suddenly dropped like stones to the floor.
They lay like this for about a minute then did it all over again another 2 or 3 times, before flying off in opposite directions.
Great spectacle, but I was never really sure what they were up to.
Cheers
