Letter in The Times, Saturday 12th May 2012, from eminent person, Dr Malcom Ogilvie, hailing from distant wildlife haven of Islay (pronounced "Isla").
Quoting statistics, Dr Ogilvie disputes the well-established theory that mute swans mate for life.
A study shows that there was a divorce rate of 3% among pairs that had bred successfully, rising to 9% for pairs that had not bred.
"A lack of success definitely stimulated a search for a new partner. However, comparisons with any other life-form, including human beings, are unwise."
OK, I have been told. I will depart now from this line of thinking.
