Abstract
    Self organizing principle suggests that very simple interactions between numerous agents lead to very sophisticated adaptive behaviours on the hole system of these interacting agents. Self-organization has been evidenced as the leading principle of several adaptive mass behaviour in social animals, most I y social insects. Here we construct a model based on field observations and experiments on the social behaviours of wintering black-headed gulls, particularly roosting behaviour. This model leads from the simple rules structuring flocks of gulls till the complex adaptive system regulating the daily distribution of lens of thousands of them over wide areas. These simple rules will be linked to this complexity through spatial structure of daily moves and nocturnal roosting behaviours. This model is both an illustration of the self-organizing principle as a mean of regulating bird dispersal and a new hypothesis about the function of communal roosting behaviour in birds.
