Syrinx is the name for the vocal cords of birds. It is a organ located at the base of a bird's trachea. It can help a bird sing. The syrinx produces sounds without the vocal cords of mammals. The sound is produced by vibrations of the walls of the syrinx or vibrations within the air flowing through the syrinx. The syrinx enables some species of birds to mimic our speech. Such birds are parrots, parakeets, and mynas.In some songbirds, the syrinx can produce more than one sound at a time. A male bird is usually the one who sings. When he sings, he is trying to attract a mate or he is warning other birds that they are in his territory. For further information see Bird call or whistling.
