Roe deer whistle, Oroqen, Ewenki, Daur and other ethnic edge air-sounding instruments. Because it is made of birch bark, it is also called birch bark whistle.

Oroqen and other ethnic hunters created a small hunting musical instrument - the roe deer whistle. Every July and August in summer, when the roe deer juvenile hair is not retreating, the hunters hide in the jungle and blow the roe deer whistle that simulates the roe deer cry. The female roe deer who went out for food will quickly run back, and the wolves and black bears in the deep forest will also search for the sound and come to prey on the roe deer cubs. The hunters work together to kill roe deer, and sometimes they can also hunt down wolves and bears, which can be said to be a good harvest.

The roe deer whistle is folded from a piece of birch bark. The bark is 5 cm long and 2 cm wide. Fold it in half and cut it with scissors into a flat shape on the upper arc and the lower part, like a half thumb. The periphery is pasted with gum, leaving a gap at the top of the arc. For the mouthpiece, the mouthpiece is 0.4 cm to 0.6 cm long and 0.2 cm wide. Two roe deer whistle are tied side by side, that is, double roe deer whistle.
