| Résumé : | The European Shag Stictocarbo aristatelis is dimorphic in body size: males are 22% heavier than females. We used molecular techniques to sex of 25 male and 18 female chicks in colonies from the Cies Islands (NW Spain). Discriminant functions were then obtained based on morphometric variables (culmen, head, wing and tarsus length) measured throughout the growth of the sexed birds. Once chicks were 25 days of age the discriminant functions accurately classified over 95% of cases, and at |
