Upping your knowledge about swans

My brother's second favourite joke is to list five facts about swans:

1. They all belong to The Queen
2. They mate for life
3. They can break your arm with a single blow from their wing
4. They only make noise when they're dying
5. There are only five facts about swans.

Hilarious. My love of swans extends to having one tattooed on my back, and I'd like to set the record straight, because none of these facts are true.

Under Royal Prerogative, the Monarch owns all wild mute swans living in open water - not all swans, just the ones you would immediately think of if someone asked you to picture a swan. Curved neck with a black knob atop.

Realistically, the Queen only exercises her ownership rights on some stretches of the Thames and its tributaries; Bewick's and Whooper swans are exempt; as are any marked by the Vintners' and Dyers' Livery Companies, which were granted their rights of ownership by the Crown in the fifteenth century.

The marking of swans along the Thames is carried out every July, in a week-long census called the Swan Upping. This year, the census starts today.

As romantic a notion it is, swans don't mate for life. A mating pair are monogamous, form a strong bond, and work together to rear their cygnets, but pairs do sometimes "divorce", and if one of the pair dies, the other will sometimes find a new mate after a period of grieving.

The myth of the dying swan has inspired art: the poem, and in turn, the ballet. As for making no noise, well, Whooper swans are named after their loud, honking call. Likewise, mute swans earned their moniker with their silence. But you will hear a mute swan coming from the vibrant throbbing of its wings in flight, and prepare for plenty of hissing, snorting and grunting if you get too close to one of its babies.

Swans are fiercely protective of their young. They will act aggressively if their family of cygnets is threatened. But they can't break your arm with their wing. Birds can fly because their bones are full of hollows, making them very light. Human bones are much more dense, so unless you're suffering from osteoporosis (which results in bones having a honeycomb structure similar to that of a bird's) a swan is much more likely to break its wing with your arm, rather than the other way round.

The fifth fact about swans is that there are five true facts and more to read at the British Waterways' website, Waterscape.

All photos from my recent visit to Abbotsbury Swannery in Dorset, the largest colony of swans in the UK and the only place where I can be persuaded to spend two hours outdoors on a very hot summer's day.

  1. Nicely written. I didn't realise Wellcome Images had taken a photo of your tattoo.
