Among the bird species, this crested penguin is distinguished by a unique characteristic

You seem to be describing a member of the crested penguins, a more extensive group. Penguins classified as crested penguins have characteristic crests or plumes on their heads. These crests lend them a distinctive and occasionally humorous look.

Among the several species of crested penguins are the Royal, Macaroni, Snares, and, perhaps most well-known, Rockhopper penguin. The charm of these endearing birds is increased by the fact that all species in the crested penguin group have crests on their heads, but having different features and environments.
