Bird Note Plus: A Way to Get More Bird Note in Your Life

Nearly all birds produce sound through an organ unique to birds, the syrinx. In many songbirds, the syrinx is not much bigger than a raindrop. Extremely efficient, it uses nearly all the air that passes through it. By contrast, a human creates sound using only 2% of the air exhaled through the larynx. Birds whose syrinx is controlled by only one set of muscles have a limited vocal range. This Song Sparrow, using several pairs, can put forth a cascade of trills and notes.
