Feeding Habits
Greater Kestrel predominantly consumes invertebrates like grasshoppers, termites, beetles, and solifugids. They also eat lizards, small birds, mammals, and snakes. Utilizing perch hunting and hovering tactics, greater Kestrel captures prey mostly on the ground and is known to exploit wildfires to seize fleeing animals. Surplus food may be stored under vegetation or stones.
Habitat
The greater Kestrel is typically found in arid, open regions including grasslands, savannas, and semi-deserts, often associated with scattered acacia trees. Its favored terrain has ground cover less than 50 cm high. This species inhabits broad geographic expanses at elevations from sea level to 2150 m, with a preference for altitudes between 800 and 1800 m. Habitats contain sparse vegetation, semi-desert scrub, and short grasslands with the occasional presence of trees and bushes utilized for roosting and nesting.
