Attacked: Parrots Sid and Nancy were mutilated in a bizarre incident at Wicksteed Park
Police are trying to track down cruel thugs who chopped the feet off two parrots at a popular children's theme park.
The criminals then left the exotic birds to bleed to death, so that the parrots had be put down when found by park bosses.
The mutilated birds, known as Sid and Nancy, were discovered this morning lying on the floor of their cage covered in blood and fighting for life.
Vets at Wicksteed Park, in Northamptonshire, were forced to euthanise the birds, which are worth £1,000 each.
Police are now offering a £500 reward for information which leads to the arrest of those responsible for the unexplained attack on the two-year-old Orange-winged Amazon parrots.
Officers believe the animals were lured to the edge of their aviary so the attackers could reach their feet.
John Roberts, managing director of Wicksteed Park, said the incident had 'sickened everyone'.

He said: 'The cages in our aviary are mink-proof and the way the birds' feet had been cut suggests that they were pulled through the cage.
'The vet who examined the birds said that the fact that they were still alive this morning would suggest that this was done in the early hours of today.
'This is an awful incident which has sickened everyone involved with the park and we are doing all we can to help police catch the people responsible.'
The park's head gardener, who looked after the birds' cage, discovered the scene this morning.
Vets who examined the two birds confirmed they were attacked by people rather than by another animal.
The parrots were donated to the park in April this year.
Witnesses are asked to call Northamptonshire Police on 101, or Crimestoppers, anonymously, on 0800 555 111.
