Silence on the water often means something special is happening—have you noticed how swans seem to turn lakes into slow-moving classrooms? A mute swan glides across calm water with its cygnets in Hesse, Germany. This scene is common across European lakes and river landscapes, from Lake Constance and the Mecklenburg Lake District to restored river channels in many towns and cities. These waterways provide sheltered shorelines and abundant aquatic plants, the swan's primary food source.

Cygnets start copying their parents early. How do they learn to feed? By mastering 'upending,' tipping forward to dip their heads underwater and reach plants rooted on the lake or river bed. Under constant adult supervision, the young gradually explore their surroundings. Their soft grey colouring helps camouflage them from predators during their first weeks, while their well-known white plumage usually develops in their second year. Watch closely and you'll see more than a peaceful family outing. It's training in progress, shaping future strong swimmers.
