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, nine thousand 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.
