The eared grebe, a small freshwater diving bird, is also known by other names such as the black-necked grebe, horned grebe, and the podiceps nigricollis. These synonyms are derived from the physical characteristics of the bird, such as the distinctive black neck of the black-necked grebe and the short, curved "horns" on the head of the horned grebe. The scientific name, podiceps nigricollis, translates to "black-necked foot," further emphasizing the bird's defining feature. Despite the various synonyms, the eared grebe remains a unique and fascinating bird that can be found in bodies of water across North America.
