Conservationists have attempted to attract gannets to the predator-free island for 40 years with the decoy birds, that were repainted and moved to higher ground in 2016.
A solar-powered speaker system emitting bird calls was also repositioned, helping attract three gannets a few weeks ago.
However Nigel shunned the new arrivals for his concrete friends and remained on a different side of the colony.
Tragically, Nigel’s body was found next to his concrete love this week by Department of Conservation ranger Chris Bell, who also lives alone on the island.
