Jer-Falcon, Falco rusticolus.
It is a bird of prey, the largest of the falcon species. The female is much larger than the male. For centuries, the gyrfalcon has been valued as a hunting bird in the art of falconry. In the medieval era, the gyrfalcon was considered a royal bird. It is a very polymorphic species, so its plumage varies.
