The shoulders and tail are dull black with buff-colored, rather than white, markings on wings and rump. This coloration is the same in both genders.The song of the American goldfinch is a series of musical warbles and twitters, often with a long note. A tsee-tsi-tsi-tsit call is often given in flight; it may also be described as per-chic-o-ree. While the female incubates the eggs, she calls to her returning mate with a soft continuous teeteeteeteeteete sound entirely. The young begin to use a call of chick-kee or chick-wee shortly fleeing, which they use before they have left the nest completely. There are two defense calls made by nesting by nestlings; a nesting call is made by adults; they are used to be quietly distracted by the crunches and other markings in the goldfinches
