Notes on Whooper Swans
Whooper swans are mainly winter visitors; they can be distinguished from a mute swan by the shape and colour of the bill. They are high flyers - a flock of whooper swans were seen in 2015 flying at an altitude of 29,000 ft!
You can find out more about Whooper Swans on the RSPB website.
