Abstract Today, aquatic and aquatic fauna have high value in many aspects and are considered as indicators of biodiversity in studies. Therefore, the present study was conducted with the aim of studying the trend of changing and comparing the indices of diversity and density of aquatic and aquatic birds in the wetland of Shirin Sou dam in Hamadan province, it was an indicator for 1 year. For this purpose, the birds of this wetland were counted from October 2009 to September 2010. The results showed that the highest bird density in the month of November was 23.77 hectares. The highest and lowest values of Simpson's index in Shirin Su Dam lake were recorded in March (0.93) and March (0.69) respectively. Also, the highest and lowest values of Shannon diversity index were in October and October (4.40) and Bahman (2.5). For the beryllium diversity index, the highest and lowest values, as well as the Shannon diversity index, were shown in October (4/10) and Bahman (1.6). In terms of Simpson's uniformity index, the highest and the lowest uniformity were reported in Shirin Su Dam lagoon in February (0.7) and May (0.27). For the Camargo uniformity index, Simmons index was the highest and lowest in Bahman (0.68) and May (0.27). For the Smith Wilson uniformity index, the highest and lowest values were determined in February and March and were respectively 0.8 and 0.36 respectively. The maximum and minimum densities in the survey period in the wetland of Shirin Sou dam were allocated to the months of November (23.78) and Bahman (1.17), respectively. The number of aquatic species in different months of the year was more than aquatic species. But the abundance of aquatic birds has always been more than aquatic. The Shirin Su Dam Lake seems to be better and more capable of providing nutritional resources for aquatic species. And this issue has also been found by observing the abundance of aquatic birds in relation to aquatic species.

Bavanat County, with an area of 4992 km², is located in north east of Fars province. During a long-term avifauna survey in the area which lasted 8 years (2007-2014), 85 bird species belonging to 12 orders and 32 families, identified and reported. The order Passeriformes with 61 species was the most diverse order in the study area. The most diverse families were Turdidae, Fringillidae and Corvidae with 18, 6 and 6 species respectively. Due to lack of natural and human made waterbodies in the study area, only one water bird species was recorded in Bavanat County. The County has a suitable habitats for the presence of terrestrial birds, especially in the spring and summer seasons.

Motacilla alba has three subspecies in Iran including M.a. personata, M.a. persica and M. a. dukhunensis. There is some evidence to support hybridization The among these subspecies. In this study, morphological differences between two subspecies of White Wagtail in Iran including M.a.personata and M.a.persica. were investigate For this purpose, 17 specimens were collected from South and North East of Iran during the spring and summer of 2011. Then seven primary variables were and six calculated ratios for comparison in multivariate analyses using Past program measured . Also coloration of head, forehead, crown and throat between to subspecies Were Compared. T test revealed that five characteristics were significantly different between two subspecies (P
