Saker falcon

In the breeding season, small mammals such as ground squirrels, hamsters, jerboas, gerbils, hares and pikas may make up 60 to 90% of a saker pair's diet; at other times ground-dwelling birds such as quail, sandgrouse and pheasants, and more aerial birds such as ducks and herons, make up 30 to 50% of the prey, and it may also eat large lizards.
