The humble House Sparrow (a bird I might add with buckets of character and is greatly underappreciated) is struggling in London. However a colony of them can be found with three Lowland Gorillas in Regents Park Zoo. Some prisoners at Spring Hill Prison near Aylesbury are making 10 nest boxes for the birds which will be ready in time for Spring.
Jonathan Baillie, head of field conservation at the Zoological Society of London hopes that the new boxes will enocurage the Sparrows to remain and breed in "Gorilla Kingdon".
Apparently Gorillas and Sparrows go back a long way at the zoo. Guy the Gorilla was known for his habit of picking up sparrows, inspecting them and then putting them back down gently.
In the past 25 years the number has crashed by 62 per cent.
