Biodiversity of bird species in Sefidkuh protected area of Khorramabad, Lorestan

Sefidkoh protected area is located in the vicinity of Khorramabad city, the capital of Lorestan province. This proximity to population centers confirms the need to pay attention to Sefidkoh. Information and research documents published on the diversity of plant and animal species and the habitat of this area are very limited. In the present study, the diversity of bird species in Sefidkouh Khorramabad protected area of Lorestan was investigated in 2016 and 2018. Birds were observed in the months of Bahman, March, April, Ardi Behesht, Khordad, and July of 2016 and 2018. In every month, two days between the 10th and 15th days of the fasting month, on days when the weather was clear and there was no rain, it was done at 8-10 am in Paish area. Observation of the species was done by moving slowly and ambushing the authors of the article in the area. And biodiversity indices were calculated with past software. 24 genera belonging to 9 orders of Iranian birds were identified in the region. The sparrow order with 8 genera and 15 species and the falcon order with 5 genera and 12 species were the most diverse orders identified in the region. 5 species of small falcon, falcon, golden eagle, Egyptian vulture, and bell-winged warbler are in the protection categories in the observed area. The Egyptian vulture is a rare species and is in danger of extinction. 5 aquatic species and 43 terrestrial species were identified. Species diversity was more in 2018. The species predominance was more in 2016. Fisher's alpha uniformity index and diversity index were higher in 2018.
