Lesser Noddies: Flying High in 2024!

For the 2024 Lesser Noddy Census, we continued using the established methodology detailed in the Seabird Monitoring Census of Seychelles. By focusing on 11 zones across Fregate Island, we assessed population density through 70 randomly generated census points, each covering 50 m². These data points allowed us to estimate the Lesser Noddy population with accuracy. Using GPS and QGIS mapping software, we updated the distribution map, ensuring researchers could easily reference and build on this work in the future.

Highlights from This Year’s Results
The 2024 census revealed exciting growth! The Lesser Noddy population rose 7% compared to 2023, reaching an estimated total of nearly 250,000 birds.. Additionally, the distribution area expanded significantly from 15.3 hectares to 18.7 hectares. The increase in density across plots reflects the continued vitality of these seabird colonies.

Looking Ahead
The census was delayed this year due to later-than-usual nesting, potentially impacted by coral bleaching events that disrupted food availability. Despite these challenges, the increase in population and distribution highlights the resilience of Fregate Island’s Lesser Noddy colonies. These findings serve as a testament to the importance of ongoing conservation efforts, ensuring the island remains a haven for these remarkable seabirds.
