Birds of Oeno Atoll, Pitcairn Islands, in September 2025

A 2025 survey of Oeno Atoll, Pitcairn Islands, reveals significant seabird population recovery following the eradication of invasive Polynesian rats in 1997. The study highlights asynchronous breeding patterns and high reproductive success across multiple species, with colony sizes surpassing pre-eradication estimates. In contrast, Henderson Island's ground-nesting seabirds continue to face predation pressures. The research emphasizes the importance of long-term monitoring to understand breeding phenology and population trends, underscoring Oeno Atoll's role as a critical seabird stronghold in recovery.
