One of them first appears in the game's prologue, producing a blizzard on Donkey Kong Island that freezes it in the process, followed by. “It’s very cool that the team was able to identify two individuals in their sample as laying females,” says Helen James, curator of birds at the Smithsonian National Museum of Natural History in Washington DC.
