Functional diversity is defined as the value, range, distribution and relative abundance of functional characters (= traits) of the organism that constitute an ecosystem. These are the characteristics measured at individual level and that influence in growth, breeding and survival, and/or in the effects to the organisms on the ecosystem. The organisms can be described in terms of their functional relationships with respect to different habitat characteristics. Birds are interesting to assess the functional answers to modified environments, being affected by loss of natural environments, or favored by the presence of non - native matrix. The goal of this work is to know the functional diversity of birds in riparian forest in the piedmont forest of Northwestern Argentina, identifying structural variables of riparian forests that influence in the structure and function of the functional groups of birds. We selected six functional traits in 194 species of birds recorded in riparian forests, and six structural variables of these forests. The data were treated using RLQ Analysis, allowing functional traits to be incorporated to analyze species ? environmental relationships, and therefore the study of relationships between the attributes of species and environmental conditions. Structural variables showed clear separation of sites allowing a distinction between ?disturbed?/?non ? disturbed? sites. Certain traits such as body size and guilds are ecological characteristics that make birds more and less prone to remain in specific sites.
