The King’s Swan Marker, David Barber, called the previous growth in population “very positive”, despite there having been a fresh outbreak of bird flu over the winter months.
Now on his 34th swan upping, he said cygnets faced a difficult start in life, with risks from predators like birds of prey, foxes and dogs, as well as disease and pollution.
“The conservation of this protected species is very important, as is educating people all about it,” Barber added.
“We have a lot of school children who come along and they absolutely love it.”
