Swan swam in. Swim, swan, swim! Swan swam out again. Well swum, swan!

Nic on Silhouette has posted a fascinating time lapse video.  Headed downhill on the Grand Union Marsworth lock flight, they found themselves sharing Lock 41 with a swan.  Sensing an easy passage, the swan then joined them at the next lock, 42. 

At Lock 43, Silhouette was joined by the swan's whole family - cob, pen and cygnets all together.  This is the sort of story I would have 'yeah-righted'.   Except it's here on the timelapse video.  Swan swims in about 1 minute in.  Well caught, Nic!

I've shared a lock with fighting swans, and compared it to a cockfight.

It's dramatic and entertaining, and if you were an impresario you could probably attract quite an audience to a swanfight in a lock.  Not to mention a few bookmakers. 

But BW are wise to this.  A couple of years ago I came upon this warning on the Caen Hill locks at Devizes.

Swans quietly hitching a ride - especially en famille - must be rarer.  And families rare resort to fighting on journeys. Unless you know better?
