Predicting the sex of kelp gulls by external measurements
Male and female Kelp Gulls (Larus dominicanus) are not clearly sexually dimorphic and are thus difficult to identify in the field. This paper evaluates sexual size dimorphism in this species and provides a reliable method for predicting the sex of measured individuals. Discriminant analysis of six m...
