Resumen

Primera observación de un nacimiento diurno en monos mirikiná silvestres (Aotus azarae) de Formosa, República Argentina. Los partos diurnos son infrecuentes en los primates, por lo que se ha sugerido que parir durante la noche tendría ciertas ventajas adaptativas, como disminuir el riesgo de predación o las agresiones a las madres y crías. Reportamos el primer evento de parto diurno observado en monos mirikiná, proporcionando descripciones detalladas de la secuencia de parto. Los mirikiná son pequeños primates arbóreos, únicos en sus patrones de actividad y poco comunes en su organización social de vida en pareja y su sistema de apareamiento monógamo. Nuestras observaciones, al proporcionar información sobre las estrategias comportamentales de los mirikiná durante los partos, contribuyen a un mejor entendimiento del potencial valor adaptativo del momento del día cuando se producen los nacimientos.
