In a centuries-old tradition, farmers in northwestern Iceland scour remote coastal plains for the down of nesting eider ducks. High inside a vast cave in Borneo, men perched atop rickety ladders collect swiftlets’ nests, a delicacy believed to be a cure for almost anything. Eiderdown and edible birds’ nests: both are luxury products, ultimately destined for the super-rich. To the rest of the world these materials are mere commodities but to the harvesters they are all imbued with myth, tradition, folklore and ritual, and form part of a shared identity and history. These objects are two of the seven natural wonders whose stories Harvest tells: eiderdown, vicu?a wool, sea silk, vegetable ivory, civet coffee, guano and edible birds’ nests.
