Nest Survival of Chestnut-capped Blackbird in Wetlands in Argentina

This study on the Chestnut-capped Blackbird (Chrysomus ruficapillus) highlights key factors influencing nest survival and breeding performance in wetland habitats. Understanding the variables affecting nest success is crucial for conservation efforts as these environments face increasing degradation. The research emphasizes the role of nest site features, such as height above water and concealment, in daily nest survival rates (DSR). By identifying these factors, the study contributes to a better understanding of the species' breeding biology. The results are useful for guiding habitat management and protection initiatives that aim to preserve species that depend on vulnerable wetland ecosystems.
