A pair of Hawaiian geese, or nene -- called so for their "nay nay" coo -- recently returned to a national wildlife refuge on the North Shore of Oahu. It's the first time the birds have been seen there since the 1700s.
Earlier this week, the U.S. Fish and Wildlife Service confirmed that the mating pair had successfully hatched three goslings. The wildlife officials said the geese got there all on their own, without the help of humans.
