The study of biodiversity changes of birds in different seasons (Case study of Kolah Ghazi National Park)

In this study population changes, density and diversity of birds in 4 study stations with different habitat type, which were consider as a surveillance stations for each season were estimated by linear transect method during one year (1395-1396). In order to determine specious diversity used indexes of Simpson, Shannon-Weiner and Brillouin, and for uniformity were calculate Simpson and Camargo indexes. For evaluating specious diversity were used Ecological Methodology. During this study 74 specious of birds were observed and identified the most frequency were belonging to Galerida Cristata, Ammomanes Deserti and Alectoris Chukar species. According to the results the most amount of diversity index (4.091 and 4.372) were belong to winter season, which expresses the most species diversity, and the lowest amount of diversity changes (3.607 and 3.221) were belong to fall season which expresses the lowest species diversity.
