Ever seen those parakeets, largely in south west London but spreading to most other parts? The noisy birds are feral rose-ringed parakeets, known as the Kingston Parakeets or the Twickenham Parakeets, the flock is believed to number about 6,000 with a population in Britain of roughly 50,000.
Experts are unsure of their origins, however the stories are as colourful and varied as the birds themselves. Some say they first appeared in the British skies after escaping from the set of the Humphrey Bogart movie The African Queen, filmed at Isleworth studios in 1951.
Others argue they have bred from a pair released in Carnaby Street in the 1960s by the rock star Jimi Hendrix.
Still others suggest they were first liberated from a private collection during the Great Storm of 1987.
A beautiful and pesky (according to some) addition to the London aviarian scene.
