Why can parrots talk

The secret of why parrots talk lies in their special physiological structure: the sounding tube and tongue. Although they can speak, the parrot’s sounder is different from the human vocal cords. The parrot’s sounder is called the sounding tube, which is located at the junction of the trachea and bronchus. It is composed of 3-6 pairs of deformed bronchus adjacent to the left and right after the expansion and deformation of the lowest trachea.


General birds can make sounds of different frequencies and levels, because when the air enters the sounding tube, it makes different sounds with the vibration of the sounding tube wall. In addition to the most basic bird characteristics, the vocal organs of parrots are more perfect than ordinary birds. In the parrot’s singing tube, there are four or five pairs of special muscles – singing muscles, which regulate the diameter, sound rate and tension of the singing tube. Under the control of the nervous system, the Ming muscle contracts or relaxes, resulting in a chirp.

In the whole structure of the vocal tube, the vocal tube is also very similar to the human vocal cord structure, except that the human vocal cord is 20 cm from the throat to the tongue, at a right angle, while the parrot’s vocal tube is 15 cm from the tongue, at an obtuse angle of approximately a right angle. This angle is the key to determine the syllable and tone of pronunciation. The closer to the right angle, the stronger the sense of syllable and tone. Therefore, parrots can produce cadenced sounds and syllables like humans.

Besides the tongue, the parrot’s tongue is very developed, smooth, fat and soft, and its shape is very similar to that of human tongue. It is precisely because of such standard vocal conditions that the parrot can emit some simple but accurate and clear syllables.
