According to the Daily Mail:
They're an odd couple in every sense but a monkey and a pigeon have become inseparable at an animal sanctuary in China.
The 12-week-old macaque - who was abandoned by his mother - was close to death when it was rescued on Neilingding Island, in Goangdong Province.
After being taken to an animal hospital his health began to improve but he seemed spiritless - until he developed a friendship with a white pigeon.
The blossoming relationship helped to revive the macaque who has developed a new lease of life, say staff at the sanctuary.
Now the unlikely duo are never far from each other's side, but they aren't the only ones to strike up an unusual friendship.
Earlier this year a pig adopted a tiger cub and raised him along with her piglets because his mother couldn't feed him.
And in 2005 a baby dear named Mi-Lu befriended lurcher Geoffrey at the Knowsley Animal Park in Merseyside after she was rejected by her mother.
