One of the brightest colored birds in the Southwest, the hooded oriole’s brilliant orange “hood” and black throat seem emphasized by desert sunshine. The hooded oriole is more slender than other orioles and is the only oriole in the United States with an orange crown. Both sexes are 7 to 7 3/4 inches long with a thin, black, slightly downcurved bill. They sing in a warbling, throaty whistle, interspersed with chatter. The call note is a liquid, whistled wheet.
