Delight that the most cygnets hatched in six years at Swanpool Nature Reserve in Falmouth was short-lived after three disappeared.
The mating pair of swans at the reserve had managed to hatch eight of the nine eggs, but by Friday only five remained.
Pete Lochrie from the Swanpool Forum said: "To have eight hatch is a huge success, as this is the largest number we have had for six years.
"However, it is sad that three have been lost so quickly. The likelihood is these were taken by foxes, seagulls or crows.
"We are hoping that all five of the remaining cygnets survive into adulthood."
And he said people are welcome to take a look and even feed them. "They particularly like corn or fresh grass cuttings," he added.
