"Odd couple" doesn't begin to describe Walnut, a female white-naped crane, and her caretaker at Smithsonian's National Zoo. The pair have formed a connection mirroring two lifelong mates. From dancing together to letting out unison calls, witness their unique bond and learn how it's helping conserve an endangered species. Then meet the Zoo's new kiwi chick, the first born there in decades. Caretakers show what makes these flightless, nocturnal New Zealand birds so special and give a look at how to care for a precious kiwi egg about to hatch.
