New Zealand bird

Andrew Digby works to protect the kakapo, a critically endangered New Zealand bird. To know them is to love them, Digby says of the large, flightless, nocturnal parrots. During the breeding season, which happens every few years when the rimu tree fruits, Digby spends months on the four predator-free sanctuary islands that are the kakapos’ last refuge. (Deidre Vercoe/New Zealand Department of Conservation)
