Identification of grassland birds and their relationship with the rangelands of Arasbaran protected area in the spring and summer of 2016 with a binocular and telescope with direct observation and counting species were conducted and 74 species of rangeland birds belonging to the 20 family were identified. Species diversity was determined using Ecological Methodology software. Most of the varieties of Margalf and Manhinnik indices were 8,363 and 3.317 in March, respectively, and the lowest in August was 7.915 and 2.037 respectively. The highest dominance in September was 0.1183 and the lowest value in June was 0.0504.Family Turdidae with 12 species with the most diversity and 7 families with one species were least in the region. The relationship of birds with pasture habitats was nutritional or multi-use. The Family of Accipiteridae and Falconidaqe were dependent on the nutrition of the rangelands such as reptiles, and the Muridae species. Relationship of birds with grasslands habitat are in two-way and play an important role in pollination and insect population balance. Because birds are part of the constituent elements of the ecosystem, they are affected by the nutrition and transfer of plant seeds and are affected by the biological conditions of the rangelands.
