Thanks a lot! I wasn't sure which of the Yukaghir languages it was as I found two different spellings for the second song: Чахадан and Чаhадаан (the letter -h- (-ҕ-?) and the doubled -a- made me think it could also be Southern Yukaghir).
Even though Evenki is already represented...
... I thought this song was worth a post: It is called Мит Эвэнкил ("We are Evenki").
