Northern Cardinal singing (Cardinalis cardinalis) Maine, Minnesota, Texas, New Mexico, Arizona, California, Mexico, Belize, Guatemala. | BIRDS & Nature

Northern Cardinals have vocal abilities that surpass even the most accomplished human singers. When cardinals sing, they sweep their voices from the high to low end of their ranges many times in just seconds. The secret is in the clever way cardinals use their two-sided vocal organ, called the syrinx. By dividing their vocal range between the two sides, cardinals can sing complex songs rapidly.
