London Evening Standard - 11th October 1984:
'An Arctic penguin crash landed (even though penguin's are flightless!!) in London's Sloane Square, in September 1984 after being "...blown hundreds of miles off course". It was believed to be the first such visitor to London under such conditions on record. Named Marianne, the young bird was looked after by an RSPCA inspector, who released her at Portland Bill, Dorset on 10th October after nursing her back to health.'
Hoax ? Zoo escapee ? You decide!
