The Mongolian tribe based in Bayan-Ölgii have used golden eagles to hunt prey during the bleak winter months for centuries, an extraordinary example of a relationship between humans and semi-wild animals.
There are an estimated 250 eagle hunters in the area, which is located in the Altai Mountains in western Mongolia and takes five years to finish training with eagles to become an eagle hunter or berkutchi.
With the younger generation moving away to cities and preferring the comforts of modern living, the modern Kazakh eagle hunters are a dying breed. Despite this, many eagle hunters still pass on their skills to their sons and daughters.
Zay Yar, a 36-year-old photographer, spent some time in western Mongolia documenting the life of these incredible people, capturing their traditions as the tribe hunt on horseback and care for their eagles.
