Some Birds Have Two Voices

The amazing vocal organ found in most birds, the syrinx, has two sides, with different sets of muscles and nerves controlling each side.  That lets some songbirds sing two separate melodies at the same time. The Veery, a species of Thrush, can even sing a rising melody and a falling melody simultaneously with the two halves of the syrinx! More info and transcript at BirdNote.org. Want more BirdNote?
