Offering a perspective rarely seen, Up in the Canopy explores the rainforest layer by layer, as we climb the incredible Kapok tree - a 100-metre tropical tree in the heart of wildest South America - in search of the elusive Harpy eagle which lives almost exclusively at great heights. As told by James Aldred, author of The Man Who Climbed Trees, and published in conjunction with the Royal Botanic Gardens, Kew.
