Eagle-bone whistle

"The Lakota also use an eagle bone whistle during the Sun Dance."

"The sacral power of the eagle is also represented by the eagle-bone whistle."

"The eagle-bone whistle is a traditional vehicle for prayer in [some] Sun Dance."

"The whistle signifies that the eagle knows no evil on this earth, and the Indian ... passes his prayer through that while he is blowing to the Almighty; and there isn't supposed to be any evil in that while he is blowing his whistle."

"There is no time or need here to wallow in distinctions between a feather-and-bone raptor and a bone whistle avian mysticism; one would no doubt end in dichotomous Western readings thereof, an ideological spectrum ranging from sheer superstition to pure embodiment of the One."
