Aitvaras is a nature spirit in Lithuanian mythology. It is also known by other names, such as Atvaras, Damavykas, Pūkis, Sparyžius, Koklikas, Gausinėlis, Žaltvikšas, and Spirukas, and is identical to the Latvian Pūķis. An Aitvaras looks like a white or black rooster with a fiery tail like a meteor. An Aitvaras is said to hatch from an egg of a 9- to 15-year-old rooster. If an Aitvaras dies, it becomes a spark.
