New Zealand's Rare Dotterels Stage Dramatic Recovery After Cat Culling

New Zealand's southern dotterel population has rebounded sharply following coordinated efforts to control feral cat populations, offering conservationists a rare conservation success story in the region. The critically endangered bird species increased by 52 percent over a 12-month period, growing from approximately 105 individuals in early 2025 to an estimated 160 birds by April 2026.

The gains follow an intensive predator management campaign centred on Stewart Island, where feral cats have posed a significant threat to the dotterels' breeding and survival. Wildlife authorities intensified their focus on eliminating the invasive predators, which have devastated populations of the flightless or weakly flying birds. The immediate results have demonstrated the effectiveness of targeted intervention in reversing the species' decline.

Conservation officials have cautioned that sustained management of the feral cat population will prove essential for the dotterels' long-term viability. The bird's precarious status means that any gains must be carefully maintained through continued monitoring and predator control measures. The programme represents part of New Zealand's broader efforts to protect its unique native fauna from introduced species that have historically threatened endemic bird populations across the country.
