Raróg

The Rarog in Polish mythology or Slavic mythology is a hawk, falcon, or fiery dwarf who turns himself into a whirlwind. The word 'Rarog' seems to be a late bastardization of the name Svarog. In Lusatia and the Urals it was customary to throw a knife into a whirlwind to kill the demon residing in it. Bulgarians, Russians, and Pommeranians still cast themselves face down before a whirlwind to ward off misfortune and illness. Russians would shout "a belt around your neck!" in order to strangle the demon.

Also known as Zhar Ptitsa, or Ptak Żar.

This is also Polish name of Saker falcon, Falco cherrug.
