Considering the Situation and Conditions of Wetland Ecosystems in the World, Many Different Species of Birds are Ecologically Dependent on the Lagoons and Through Various Compromises these Unique Ecosystems are used as a Suitable and Important Habitat To Make. Therefore, The Study of the Variation and Fluctuations in the Population of Aquatic Birds During Different Years can be a Biological Indicator of the health Status or the Presence of Threats in Wetland Ecosystems. In this Study, to Study the Biodiversity of Birds Waterfowl and Waders the Wintering of Poldokhtar Wetlands in 2009-2015, from Species diversity Indices (Shannon-Wiener and Simpson's Image), Species Richness (Margaluf index), Species Uniformity ( Smith-Wilson and Simpson Dominance Indexes) and for the Similarity of the Species of Birds in Different Years, the Morrista index was studied using Ecological Methodology, Species Diversity and Richness total of 16986 bird species from 6 orders, 14 dwarfs and 43 species have lived in the wetland wetlands. The density of birds at the surface of the wetlands is 52.9 and 58 Percent of the Habitats have Waders habitats and 42 Percent have Waterfowl Habitats. The Results of Survey of Biodiversity Index of Birds in Poldokhtar wetlands Showed that the Highest Variety, According to the Biodiversity Index of 2009, the lowest and the highest in 2012, the Highest Species Diversity, 2013 and 2009, the Lowest Level of Species Uniformity in the Year 2013 and the Lowest in the year 2009 Have Been the Least Species Richness of Birds. Based on the Morrista Similarity Index, the Most Similar species of the birds community in Poldokhtar wetlands related to 2012 with 2014 is the Similarity of 1 and the Least Similar Species in 2015 with 2011 with Similarity of 0.79.
