Wild Bird Trust.

Steve Boyes works to preserve and protect Botswana's uniquely pristine Okavango Delta and mitigate threats bringing parrot species to the brink of extinction throughout Africa. He is scientific director of the Wild Bird Trust.The dugout canoe pushes through the steamy African wetland for eight grueling days. Then, the reeds part, and there it is. Paradise. Thousands of elephants, hundreds of hippos, buffalo, and baboons, marshes undulating with rhinos, leopards, lions, impalas—and over it all, the deafening music of 10,000 birds. "The first time I experienced the heart of the Okavango Delta, I was brought to tears," shares Steve Boyes. "I've seen no place that approaches wildlife densities like these. It's the closest I've come to pure African wilderness."
