A rooster, especially as a poetic or storybook figure whose crow seems to conduct the morning (literary). Chanticleer is a name rather than a label. It grants the bird a role and a voice.

From Old French Chantecler “sing-clear,” a proper name given to the rooster in medieval beast tales (notably the cycle that includes Reynard the Fox). English kept the name as a common noun when it wanted a rooster with personality.
