John Chaworth-Musters sent 4 mallard ducks to Major John Whitney, his son-in-law in Auckland, New Zealand, in 1887. John Patricius Chaworth-Musters sent a further 6 mallard drakes to Cecil, (Later Sir Cecil), Whitney in Auckland, who was the major's son, in 1910.
These birds, most probably caught in the decoy, played a key role in establishing this species in the wild in New Zealand where in now numbers in the millions.
