Abstract
This study was conducted in Jebel El Dayer National Park, North Kordofan state-Sudan during 2014 to 2018. This research aimed to identify Palearcatic migrant birds, all direction on the top of the Jebel was surveyed. The study depended on direct observation using field binocular, digital camera, (GPS) device for coordinating and bird types using manuals. Seven visits were done to cover the main areas where seven out of them represented the main entrances of the Jebel in addition to two areas on top of the mountain. Data were analyzed descriptively in Statistical Packages for Social Sciences (SPSS) where frequencies, means and percentages were calculated. The results were showed in tables and figures. The results of the study showed that Palearcatic migrant bird are found in high diversity. One hundred and twenty nine (129) Palearcatic migrant bird species were recorded during this research. These species included in 14 orders and thirty seven (37) families. Showed Palearcatic migration bird species that found in all directions of the study area. There were 7 species recorded in all directions of the mountain. Regarding the abundance of Palearcatic bird species, they divided index according to Nicklaus (1987). They were 5 divisions uncommon (Un) which included 43 species represented 33.3%, rare (R) encompassed 49 species represented 38%, common (C) included 19 species represented 14.7%, very rare (VR) involved 14 species represented 10.9%, and finally the lowest abundance was very common (VC) encompassed 4 species represented 3.1%. However, frequency for years 2014 showed the highest percentage 48.4% followed by 2018 which showed 40.5% and minimum percentage was in the year 2015 showed 11.1%. It also recommend setting working plan aiming at sustainable development and optimum utilization of the resources.
