En Argentina, el riesgo que los rodenticidas anticoagulantes podrían presentar para las aves rapaces locales fue reconocido inicialmente en la década de 1980. Lamentablemente, 40 años después esta primera señal alarma, siguen siendo ampliamente utilizados país y toda Sudamérica, sin haberse estudiado problema medioambiental estos pueden suponer. Aquí presentamos una revisión práctica e integral sobre intoxicación por rapaces. Discutimos su impacto, tanto individuos como sus poblaciones, también aspectos relacionados al manejo animales intoxicados a necesidad contar con capacidad diagnóstica región. La información aquí recopilada permitirá contenidos relevantes, actualizados accesibles necesarios abordar estudio amenaza conservación Argentina otros países Sudamérica. Al mismo tiempo, esperamos promueva investigaciones tema permitan dar pasos evaluar mitigar uso puede tener otra fauna silvestre
