Nigel lived for years on his own on uninhabited Mana Island off the north of the country, surrounded by concrete replica gannets.

The immobile replicas had been put in place by conservation officers who used the sound of gannet calls broadcast by solar-powered speakers in an attempt to lure a colony to settle on the pest-free scientific reserve.

Nigel was the first gannet in 40 years to make his home on Mana, arriving alone in 2013.

There he remained, alone. That is until just a few weeks ago when he was finally joined by three real life members of his species. However, Nigel failed to befriend them, and then he died.
