Abstract

The birds are one of the important elements of urban parks. We identified the birds of green spaces in 9 main parks during winter and spring 2010. In these parks, there were 92 species belonging to 31 families and 9 orders. The most Shannon Wiener diversity species (3.78) was in winter in Dolat Park which showed a stable condition in this park. The most Margalef species aboundance (6.07) was in winter and in the same park. The utmost Hill species evenness (0.84) was in winter in Shahrvand Park which showing even distribution of species, and the least Hill species eveness (0.45) was in spring in Dolat Park. The two-ways ANOVA results showed there were significant differences between winter and spring seasons in Menhinich Index and Simpson and Hill Indexes for species aboundance. According to Duncen test in chance of 95% there were significant differences in evenness species point of view in these 9 parks and results showed condition was not even between studied areas and also there were differences in parks systems management.
