The name “Birds’ Path” is used in several Uralic and Turkic languages and in the Baltic languages. Northern peoples observed that migratory birds follow the course of the galaxy[10] while migrating at the Northern Hemisphere. The name “Birds’ Path” (in Finnish, Estonian, Latvian, Lithuanian, Bashkir and Kazakh) has some variations in other languages, e.g. “Way of the grey (wild) goose” in Chuvash, Mari and Tatar and “Way of the Crane” in Erzya and Moksha.

“At the edges of Earth was Lintukoto, “the home of the birds”, a warm region in which birds lived during the winter. The Milky Way is called Linnunrata, “the path of the birds”, because the birds were believed to move along it to Lintukoto and back. In Modern Finnish usage, the word lintukoto means an imaginary happy, warm and peaceful paradise-like place.”
