With a two metre wingspan, strong hooked beak and four inch talons, harpy eagles are one of the most powerful birds of prey in the world and have been known to attack people who get too close to their nests, so when wildlife cameraman John Aitchison agreed to spend a month on a tiny platform high up in rainforest canopy in Venezuela to try and film a young eagle chick hunting for the first time, it was with some trepidation at what might lie ahead. John abseiled down from his platform each night to grab a meal and a few hours of sleep, but before dawn he climbed back up onto his tiny platform, just big enough for him and his camera. High up in the rainforest canopy, his neighbours included bellowing howler monkeys, flocks of squawking parrots and colourful butterflies as well as highly venomous snakes and stinging ants. He also had to endure some torrential storms and powerful winds. But his perseverance was rewarded with stunning views across the forest, magical misty mornings, very close encounters with the harpy chick and a most unexpected meeting between the young eagle and a very brave sloth!
