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.

The Hornbostel–Sachs system for classifying musical instruments places this group under the heading "Flutes with duct or duct flutes." [ 1 ] The label "fipple flute" is frequently applied to members of the subgroup but there is no general agreement about the structural detail of the sound-producing mechanism that constitutes the fipple, itself.
