when i was riding my bike the other day, i saw two swans copulating i was just stunned to see them biting one anothers necks, it looked fearsome and a lot of croaking, it looked to me as if they were stuck together like dogs but eventually they broke free and went completely different ways, i followed the swan the cob and watched him wash and preen him self. what i want to know if they were miles apart do they meet up again some time thanks
