Bird vocalization includes both bird calls and bird songs. In non-technical use, bird songs (often simply birdsong ) are the bird sounds that are melodious to the human ear. In ornithology and birding , songs (relatively complex vocalizations) are distinguished by function from calls (relatively simple vocalizations).
Avian respiratory and vocal anatomy. When birds inhale, air is passed from the mouth, through the trachea, which forks into two bronchi connecting to the lungs. [8] The primary vocal organ of birds is called the syrinx, which is located at the fork of the trachea, and is not present in mammals. [9]
