Talk abstract: 

For public health, economical and environmental reasons, surveying of bird populations is a major issue because of their proximity with humans. We propose passive acoustic methods that allow to assess the social structure of wild-type population and estimate several parameters of social groups.  Whole population acoustic network assessment can be a powerful tool to analyze and study important social groups of birds. However studies have focused mostly on vocal communication between two individuals and little is known about properties emerging from an acoustical network where several individuals are involved. On the other hand, animal social network analysis relies on static graphs of proximity -- proximal -- and most of the time ignore more distal information such as acoustic network of whole groups. We propose several methods and results to assess such acoustic networks and model to explain their dynamics in relation to their known social structure.
