In Russian folklore and fairytales the Firebird
(Russian: жар-пти́ца, zhar-ptitsa; Ukrainian: жар-пти́ця, zhar-ptytsia; Serbian: Жар-птица or Žar-ptica; Croatian: Žar-ptica, Rajska ptica; Bulgarian: Жар-птица, Zhar-ptitsa; Macedonian: Жар-птица, Žar-ptica; Polish: Żar-ptak; Czech: Pták Ohnivák; Slovak: Vták Ohnivák; Slovene: Rajska/zlata-ptica) is a magical glowing bird from a faraway land, which is both a blessing and a bringer of doom to its captor. Some believe it can see the future. The Firebird has its origins in the Slavic mythology.
The Firebird is described as a large bird with majestic plumage that glows brightly emitting red, orange, and yellow light, like a bonfire that is just past the turbulent flame. The feathers do not cease glowing if removed, and one feather can light a large room if not concealed. In later iconography, the form of the Firebird is usually that of a smallish fire-colored falcon, complete with a crest on its head and tail feathers with glowing "eyes". It is beautiful but dangerous, showing no sign of friendliness.Firebird (Slavic folklore) in Wikipedia
