The bird communities in the Presidential Estate of Castelporziano (Rome, Italy) were studied to determine their structure in a set of different natural habitats and during the seasons. This study area is a complex ecosystem, formed by a mosaic of different habitats, having a high biodiversity level. Bird communities of Castelporziano are characterized by high degrees of richness and complexity. Null model analyses revealed that the bird community is not randomly organized, but it depends on seasonal resource availability. Based on this study, we did not focus only on conservation level of single habitat for Mediterranean birds, but also on their seasonal importance, creating a new approach where the natural quality is evaluated in different variables.
