When thunderclouds begin to gather over Botswana’s Kalahari Desert each year, 20,000 zebras get itchy feet. As the first fat raindrops hit the dust, southern Africa’s biggest animal migration gets underway. In a never-ending quest for grass and water, the striped herds undertake an annual epic trek across the vast lunar landscape of the Kalahari’s Makgadikgadi Pans.
Bird nests come in all shapes and sizes, crafted from a diversity of materials, including fur, grasses, leaves, mosses, sticks and twigs, bones, wool, mud and spider silk. Quite a few contain man-made materials – twine, bits of wire, even plastic bags. Each is a work of art, built with just a beak! All over the world, birds in the wild arrive at diverse nesting grounds to collect, compete for, reject, steal and begin to build with carefully selected materials, crafting homes for the task of protecting their eggs and raising their young.
