Objectives
We aimed to provide a long-term, comprehensive description of Peregrine Falcon Falco peregrinus diet composition and diversity on coastal Mediterranean islands, near a major urban area, at breeding and non-breeding seasons. Methods We identified prey species from 87 remain samples of F. peregrinus preys year-round collected on 6 islands near Marseille, France (1995-2024). Prey relative abundance, biomass, and diversity indices were calculated. Seasonal, spatial, and temporal variations in diversity indices and prey taxa abundances were assessed using Kruskal–Wallis tests and generalized linear models. Results We identified 4,483 prey individuals across 180 species (i.e., species richness), with birds Conclusion Our 30-year study provides insights into Peregrine Falcon feeding ecology and highlights the high dietary diversity and trophic flexibility of Peregrine Falcons on Mediterranean coastal islands. Temporal, seasonal, and small-scale variations in the contribution of prey species to the diet may reflect factors related to prey ecology, including long-term trends in prey populations and their localized availability at or near nesting sites, stopover areas, and along a coastal flyway. |
