Abstract:The Saker Falcon (Falco cherrug) is a national level II key protected wild animal, and listed as an endangered species by IUCN. One Saker Falcon was successfully equipped with a satellite tracker on September 26, 2018 in Baoding City, Hebei Province. The bird’s migration route involved six provinces and regions of Hebei Province, Inner Mongolia Autonomous Region, Shanxi Province, Shanxi Province, Gansu Province and Qinghai Province, with the direction from east to west, and finally arrived at its wintering area of Pingchuan District, Baiyin City of Gansu Province. The migration process is divided into three stages, namely release stage, wandering period and migration period. The flight distances of each stage are 297.62 km, 1 129.69 km and 2 040.9 km respectively (Fig. 1). According to our analysis of the satellite tracking data, the bird flew during daytime and its daily flight time was 7:33 ± 2:01 to 18:12 ± 1:09, with the average of 10.44 ± 1.76 h. There were three peaks of average flight speeds in a day, being 9:00, 14:00 and 18:00 respectively (Fig. 2). In the whole migration process, the average flight speed was 45.77 ± 20.88 km/h, with the average daily flight distance was 188.65 ± 113.90 km. The bird did not have a fixed place to rest at night in the winter. The altitude of resting place was 1 500﹣2 000 m, and 90 % of the home range size was 85.5 km2. On March 7, 2019, it was found that the bird was electrocuted and hung on a telegraph pole. The electric leakage of telegraph poles could be the death traps for the Saker Falcon and other birds (Fig. 3).
