The kestrel was found in a barn on Mill Lane, Mablethorpe near the wind farm on January 22. Its right wing had been broken in several places.

It is being cared for at Mablethorpe Seal Sanctuary and Nature Centre where it will now spend the rest of its life.

Andy Hollingsworth from the sanctuary said: "The bird was taken to a local vet who removed an air gun pellet and had to amputate the wounded wing. It will now have to spend the rest of its life in captivity."

He added: "Staff here would like to appeal to your readers to keep a watch out and report anyone who is seen shooting birds of prey so this doesn't happen again."

The RSPB state that since 2003 they have received reports of 1664 incidents of bird crime involving or targeting wild birds of prey in the UK.

Georgie Bates, spokesperson for Lincolnshire Police said: "Shooting at any wild bird is a cruel and heartless act particularly when using an air weapon, which is likely to cause an injury which will lead to immeasurable suffering.

"All wild birds, their eggs and nests are protected by the Wildlife and Countryside Act 1981. Anyone convicted of an offence is liable to a fine of up to £5,000 or six month's imprisonment. We would encourage anyone with information on who was responsible for this kestrel's injuries to come forward."

Anyone with information regarding this crime should contact Lincolnshire Police on 01522 532222.
