The mother of the man with Aspergers syndrome whose two parrots were stolen is offering a reward of £400 for anyone who gives information leading to the safe return of the outstanding bird.
Two parrots were stolen during a burglary on Brierley Street in Oldham, sometime between 6pm and 9pm on Wednesday 31 January 2013.
Police believe the offenders climbed on a roof before sneaking in through an upstairs window.
They then searched the bedrooms and stole a purse, jewellery box and the two parrots.
The victim, a 41-year-old man, was at home in the living room at the time.
The "Blue Macaw" parrot was returned in early February, however the "African Grey", called Arnie, remains outstanding.
Officers are appealing to anyone who has recently bought a parrot or had one come into their possession since 31 January 2013, to check for the following characteristics:
- Arnie has a mark all the way around his beak from half way down. He can say "ring the bell" and if asked to can if he can whistle and will respond by whistling.
- When he was stolen he had a blue ring on his leg that was well worn. In places the blue had worn away to reveal silver underneath.
Detective Constable Sam Blackwood said: "The victim's family have seen what a negative effect this theft has had on him.
"These parrots form an essential part of this man's life and help him cope with his condition.
"While he was relieved to get one of them back, he still longs for the return of Arnie and his condition has deteriorated in the meantime.
"His mother has therefore gone to the extreme step of offering a reward of £400 to help get Arnie back.
"We hope this reward will encourage someone to come forward and help us find the parrot as soon as possible."
Anyone with any information is asked to call police on 0161 856 8952 or call the independent charity Crimestoppers anonymously on 0800 555 111.
