ZAOver 30 years after feral cats were eradicated from Marion Island, a conservation success, scientists observed that brown skuas, the island's top seabird predator, are breeding in new locations. Instead of moving inland as burrowing petrel populations recovered, the skuas are increasing their coastal nesting areas, which coincides with declining prey populations. The study, led by researcher Michelle Risi, highlights the complexity of ecological recovery after invasive species removal. While the brown skua population remains stable, their shifting behavior suggests unpredictable responses to environmental changes. Researchers note factors like prey preference, site fidelity, and varying petrel recovery rates may influence this pattern. The findings underscore the challenges of predicting ecosystem restoration and the ongoing impacts of climate change and disease on the island's wildlife.
