The BBC is, quite rightly, held up as one of the greatest producers of natural documentary in the world. Time and time again their award-winning productions have raised the bar in terms of never-before-seen natural phenomena, broadening our appreciation and understanding of the animal world like nothing else. Some of the incredible things their film crews have managed to capture defy belief, but now, in a new six-minute short, the department’s director John Downer explains some of the groundbreaking techniques they use to film these animals so intimately. From tiny cameras strapped to birds, to roving robots made to look like icebergs, to full replica turtles and penguins with photo apparatus inside – the list of clever spy tactics used is both ingenious and, at times, hilarious to watch. Check it all out in the video above and, if you like what you see, you can find more footage from the BBC over on Getty Images.
