What Swans Do With Their Heads Underwater


This week Britain’s BBO Wildlife Trust shared a glimpse into the underwater world of swans and ducks.

Mute swans have such long necks that they can feed on the bottom while floating on the surface. Ducks have to dive.

While the swan is feeding tufted ducks come and go, their bodies so buoyant that their feet must flap continuously to keep them submerged.

If this had been filmed in North America they would be our own species: tundra swans and ring-necked ducks.
