Sanaye Foolad wetland is one of the largest and most important semi-artificial wetlands in Khuzestan province that in terms of habitat of fish , water birds and waders is too valuable and according to the importance and special ecological values of water birds in wetland fields , awareness of changes related to the population of different species of birds , has basic role in management of these kind of areas. Therefore, the present study is done to identify and compare the density and diversity of water birds and waders come out in the second half of 2008.In this research, birds were counted monthly from October to March 2008 and according to "total count" method which is the recommended method of WI. In this wetland 13 species of water birds and waders from 7 families were identified during 6 month period of the research. Results that are achieved from frequency of bird families in sanye fulad wetland shows that in fall, Rallidae (33.98%) and in winter Recurvirostridae (36.78%) have had the maximum frequency. In the other hand, results obtained using biodiversity index shows that October in terms of Shanon-Winer &S impson diversity (2.657, 0.829), October and November in terms of Menhinx & margalf species richness (1.604, 0.527) and February in terms of Karmago and Simpson evenness index (0.892, 0.0817) possess the most biodiversity of water birds and waders during the research period.
