The Cu bird (Spanish: pájaro cu or cú) is a bird from a Mexican folktale that is unhappy with its looks. According to the legend, the other birds agreed to the barn owl's proposal to give the Cu bird one feather each and in return asked it to become the messenger of the bird council. But the bird soon started neglecting its task because instead it spent time admiring its plumage. There is a song titled "El pájaro cu" in the Mexican Son Jarocho style. According to one source, pájaro cu is a name used in the Yucatan Peninsula for the russet-crowned motmot, a colorful bird.
