Seabird's 50-Year Rescue: From Near Extinction to Hope
26 Aug
Summary
- Geoff Harrow dedicated 50 years to saving Hutton's shearwater.
- Predators like stoats and pigs threatened the species' survival.
- A new protected colony was established on the Kaikōura Peninsula.

In 1965, Geoff Harrow embarked on a quest to find an unusual seabird nesting in New Zealand's Kaikōura mountains. What began as an expedition to identify Hutton's shearwaters evolved into a lifelong conservation commitment spanning half a century. Harrow's persistent efforts, often involving repeated visits to remote mountain slopes, led to the discovery of several colonies.
Over decades, Harrow witnessed a dramatic decline in the Hutton's shearwater population, dropping from an estimated two million birds to around 500,000. Research identified stoats and wild pigs as significant threats, damaging burrows and preying on the birds. This understanding shifted conservation strategies towards predator control.
To safeguard the species from catastrophic events, a new colony was established on the Kaikōura Peninsula starting in 2005. Harrow championed the creation of a protected, predator-proof area. This initiative, involving multiple organizations, provided a vital second home for the shearwaters.
By 2015, Harrow, then 88, had dedicated around 50 years to the Hutton's shearwater. His determined, albeit obsessive, passion ensured the species' survival, earning him recognition for his significant contribution to conservation efforts in the Kaikōura mountains.
