Guillemots ( Uria aalge do not show any external sexual dimorphism. In the present research in a colony of captive guillemots the differences in behaviour between male and female birds have been studied.

The following differences in behaviour have been observed. -The male guillemots occupy the eventual nesting territory before the females. In the greeting ceremony the males show dominant agressive components in their behaviour, the females show submissive behaviour. -Generally speaking the male is the first bird to show courtship-display as an introduction to copulation. -The male is promiscuous, the female partner less so or not at all.
