This subspecies was first described by Stegmann in 1925, with the type specimen collected between Urga and Kalgan in northern Mongolia.

Physical Characteristics

The Saker Falcon is a large falcon, characterized by its robust build and powerful flight. Adult birds typically exhibit a wingspan ranging from 120 to 140 cm. Their plumage is predominantly brown with lighter underparts, featuring dark streaks that provide excellent camouflage against their natural surroundings.

Habitat

Falco cherrug progressus primarily breeds in southeastern Transbaikalia and northern Mongolia. These birds prefer open landscapes, including steppes, grasslands, and agricultural fields, where they can easily spot prey. During winter, they migrate to regions such as the Alashan and eastern Nan-shan Mountains, seeking milder climates and abundant food sources.

Diet

The Saker Falcon is a formidable hunter, preying on a variety of small mammals and birds. Its diet mainly consists of rodents, such as voles and lemmings, as well as smaller birds. The Saker Falcon employs a hunting strategy that involves high-speed dives and agile maneuvers to capture its prey, showcasing its exceptional aerial skills.

Behavior

Saker Falcons are known for their strong territorial instincts, especially during the breeding season. They engage in elaborate courtship displays, which include aerial acrobatics and vocalizations. These birds are also highly social, often seen hunting in pairs or small groups. Their keen eyesight allows them to spot prey from great distances, making them effective hunters.

Reproduction

Breeding typically occurs in the spring, with females laying 3 to 5 eggs in a nest built on cliffs or in tree cavities. The incubation period lasts about 30 days, during which the female remains primarily responsible for the eggs. Once hatched, both parents participate in feeding the chicks, which fledge approximately 6 weeks after hatching.

Conservation Status

The Saker Falcon is currently classified as Near Threatened by the International Union for Conservation of Nature (IUCN). Habitat loss, hunting, and environmental changes pose significant threats to their populations. Conservation efforts are underway to protect their habitats and ensure sustainable populations.
