As the triathletes power across Hyde Park's Serpentine lake Saturday, spare a thought for the swan families plucked out of harm's way.

Organizers say the lake's three resident swan couples — and their young cygnets — were temporarily relocated last week at the behest of the park's wildlife officer. "This decision has been made for the protection and safety of the birds during this busy time," a spokeswoman said in an email, adding that the birds were being cared for by a charity called Swan Lifeline.
