The Great Bustard is an iconic bird of Eurasian grasslands. Feeding on insects and vegetation, this bird reaches weights of up to 45 pounds, making it the heaviest bird capable of flight. With a charismatic breeding display that transforms this usually brown bird into a bustling ball of white feathers, the Great Bustard is a compelling focus for conservation and an irreplaceable part of our world’s natural heritage. The Great Bustard’s requirement for large swaths of open habitat also make it a flagship species for the conservation of temperate grasslands, the world’s least protected habitat.

Populations of the Great Bustard once stretched across the steppe zone of Asia, from Portugal to Manchuria. Today, only 2,500 individuals of the unique Asian subspecies are estimated to remain in Mongolia, southeastern Siberian Russia and northeastern China.

Dr. Mimi Kessler leads the Central Asian Great Bustard Project (CAGBP), which has worked with the Ornithology Lab of the Mongolian Academy of Sciences (OL) and the Wildlife Science and Conservation Center of Mongolia (WSCC) to collaborate on research to determine the location of remnant populations and the causes of their declines. They also carry out environmental education programs for rural youth, training a new generation of conservation biologists, developing media outreach, and pursuing conservation policy for Great Bustards.

As Great Bustards in Asia spend one-third of the year on migratory stopovers, one-third on wintering grounds, and one-third at breeding sites, a successful conservation strategy requires long-term international cooperation between countries. Mimi recently organized a conference in Mongolia focused on this task. The conference hosted participants from nine countries, who reported on the status of and threats to Great Bustards across the breeding and wintering range of the species in Asia. As a group, participants prioritized threats to the species and revised a Proposal for Concerted Action on the Great Bustard, which the Government of Mongolia submitted to the Convention on Migratory Species (CMS).
