Folklore and culture

It is said that a black crow was on an araucaria tree, when it was scared by the sound of a man trying to take down the tree with an axe. Saddened by the destruction of its home, the crow flew to the sky, when it heard a voice saying that it would be painted with the color of the sky, and be guardian of the trees. And as a guardian of the araucaria trees, even guns would deny fire towards it. This folklore is based mostly on the habit this bird has to bury araucaria seeds to consume later, helping the spread of the tree across the region, and being considered the greater disseminator of the species. But above that, it shows the importance the araucaria tree, and the azure jay have to the people of Parana. It is the official symbol of the state (State Law n. 7957 of 1984), it gives name to the highest prize in theatrical arts of Parana (Azure Jay Trophy), and is the symbol of the soccer team Parana Clube. It also inspired the comicbook superhero O Gralha (the Jay/The Crow), a superhero created by artists of
