Swans at Attenborough Nature Reserve are thought to be dying due to an outbreak of bird flu.
The beauty spot, situated to the south west of Nottingham, said that it has received "a number of reports" of the birds dying, citing the likely cause as bird flu.
It follows a number of cases at Nottinghamshire sites, such as Colwick Country Park earlier this year, as England faces its biggest ever outbreak of the disease.
