Meet rufa red knot B95. Scientists call him the Moonbird because, in the course of his astoundingly long lifetime, this robin-sized shorebird has flown the distance to the moon - and halfway back! Each February he joins a flock that lifts off from Tierra del Fuego, headed for breeding grounds in the Canadian Arctic, 9,000 miles away. Late in the summer, he begins the return journey. B95 can fly for days, but eventually he must descend to refuel and rest. However, recent changes at stopover sites along his migratory circuit - changes caused mostly by human activity - have reduced the food available and made it harder for the birds to reach.
