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)

Bloodthirsty by Thomas P. Peschak, Germany/South Africa — winner, Behaviour: birds. When rations run short on Wolf Island, in the remote northern Galápagos, the sharp-beaked ground finches become vampires. Their sitting targets are Nazca boobies and other large birds. The finches rely on a scant diet of seeds and insects, which regularly dries up, so they drink blood to survive. ‘I’ve seen more than half a dozen finches drinking from a single Nazca booby,’ says Tom. Rather than leave their nests the boobies tolerate the vampires, and the blood loss doesn’t seem to cause permanent harm. (Photo by Thomas P. Peschak/2018 Wildlife Photographer of the Year)
