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.
When blowing the roe deer whistle, place the mouthpiece between the two lips, and use the index finger and middle finger of the left or right hand to hold the lower end of the roe deer whistle on both sides, and then the air can be pronounced.
Its sound is shrill and bright, and is used to simulate the screams of roe deer juveniles. 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.
