A parrot stuck on a roof for three days greeted firefighters sent to its aid on August 13, 2018 with a four-letter tirade. Jessie, the multi-lingual Macaw, flipped the bird after escaping from her owner's home in Edmonton, north London, UK. When she could not be lured down from a neighbour's roof, firefighters were called out and told to tell the bird “I love you” – to which Jessie replied “I love you back”. But she then ruffled her would-be rescuers' feathers by telling them to “f**k off” before flying off to another nearby rooftop. The foul-mouthed pet also speaks Turkish and Greek according to its owner, but had its own choice words in English for the rescue team. As Jessie wasn't injured, the firefighters, who had been called in by the RSPCA, left her on her perch. The parrot was later reunited with its owner. (Photo by Rex Features/Shutterstock)
