Parrot to be fitted with a wooden leg

From Telegraph:

A one-legged parrot that keeps slipping off his perch is to be fitted with a 'wooden leg'. George, a ten-year-old African Grey, lost a claw after being attacked by a wild animal which broke into his cage a year and a half ago. The missing limb means whenever George tries to sleep, he slips off his perch, squawking "Bloody Hell!" in surprise. Concerned for her pet, the bird's owner Sheila Weare sought advice from experts at the University of Salford. Mrs Weare, from Crewe told the BBC: “You can tell by the way he fidgets that he's not comfortable and he has to bite the bars of his cage at night to balance." In the hope of giving bird and owner a good night's sleep, the perch will be fitted with a specially-moulded slot, into which George will be trained to insert his stump at night.

For the Russian reader, не могу не вспомнить загадку эпохи моего детства:

С когтями, но не птица, Летит и матерится.
