Our activities focus primarily on the scientific studies on biology and ecology of the endangered species of birds, bird and wetland conservation, public educations, bird surveys related with a proposed infrastructures such as wind farming and power lines.

The researchers of Mongolian Bird Conservation Center collaborating with Dr.Guo Yumin of Beijing Forestry University and Eastern Mongolian Protected Area Administration have been conducted cranes study such as White-naped crane Antigone vipio, Common crane Grus grus, Demoiselle crane Grus virgo, and Hooded crane Grus monacha along the Ulz river in Eastern Mongolia in last three years.
Totally, we tracked 150 individuals of 4 species in Eastern Mongolia to investigate their movements and migration through GSM-based transmitters. Among them, we have started a Hooded Crane Grus monacha migration survey in Mongolia for the first time.
The results of the study are as follows:
I. The autumn migration of the White-naped Crane Antigone vipio of the Ulz river began at the end of September. They arrived to Poyang lake in southern China which is their wintering area at the end of December. All the tracked White-naped Cranes wintered on Poyang lake. We observed that some of the young birds moved to the Amur population, which is a separate eastern population of White-naped cranes, during their spring migration.
II. The autumn migration of the Common Crane Grus grus of Ulz river begins at the end of September and they arrive to the northern shore of the Bohai sea in China which is their wintering area at the end of November. All the tracked Common Cranes winter on the northern shore of the Bohai sea.
III. In Mongolia, the Hooded crane Grus monacha is a non-breeding, summer visitor and passage migrant. We tracked a non-breeding young female individual in Turgenii Tsagaan Lake in Bayandun soum of Dornod province. According to the transmitter data, our tracked individual shifted to the east along the Ulz river to Tari lake, then turned to the Onon river, headed south down the Amur River valley, and passed through North and South Korea to winter in Izumi, Japan.
IV. The autumn migration of Demoiselle Crane Grus virgo begins at the end of September and arrive in India which is their wintering area at the beginning of November. During this migration, they stayed in Inner-Mongolia which is their stopover site for months, then headed to their wintering area.
