Report on a Quarter-Century of Monitoring the Galapagos Petrel (Pterodroma phaeopygia): Trends in Population, Reproduction, Phylogeny, and Future Conservation Strategies

This report presents a comprehensive analysis based on over 25 years of monitoring data collected on Santa Cruz Island in the Galápagos, focusing on populations of the Galápagos petrel. It examines key aspects of population dynamics, including reproductive success, nest occupancy, and adult population estimates, alongside phylogenetic comparisons between Santa Cruz and Santiago Island populations. In addition, the report contributes to ongoing conservation efforts by providing a thorough review of existing literature on petrel management and proposing evidence-based methodologies to support the long-term conservation of this endangered species in the archipelago.
