We have been studying migration and breeding study of raptors such as Saker Falcon Falco cherrug, Steppe Eagle Aquila nipalensis, Golden Eagle Aquila chrysaetos, Amur Falcon Falco amurensis in Eastern Mongolia since 2017. The results of the study are as follows:
We also tracked 2 chicks of one pair of Golden Eagle Aquila chrysaetos, and 5 chicks of three pairs of Steppe Eagle Aquila nipalensis in Mongol Daguur SPA “A” part. According to the transmitter data, all the tracked Steppe Eagle chicks are wintering in India. The tracked young individuals of Golden Eagles wintered in Hulun lake of China, and are now returning to their breeding area.
We have been studying the movement of 5 chicks of Saker Falcon Falco Cherrug belonging to two pairs that breed along the Ulz river, using GSM-based transmitters. The first pair nested at an artificial nest and successfully hatched 4 chicks, the second pair nested in a willow tree nest which was built by Upland Buzzard and successfully hatched 2 chicks. We managed to track three of the chicks belonging to the first pair who nested at the artificial nest. One chick is wintering in Tibet, another in Bayanjargalan soum of Tuv province, and the last one in Xiliin Gol province, China. One chick, of the second pair who nested in willow tree, was electrocuted on a distribution line belonging to Dachin Tamsag petroleum co., in Matad soum, Dornod province. The other chick is wintering in Tibet.
We also tracked one adult, male Amur Falcon Falco amurensis along the Khalkh river in Khalkh Gol soum of Dornod province, Eastern Mongolia. The chick was heading from Mongolia on the end of the August and arrived at their wintering site in early February.
