What specific facial feature gives the White-bearded Wildebeest subspecies its common name?

Answer

A very long, dark, shaggy beard hanging from the throat

The White-bearded Wildebeest is identified as a subspecies of the blue wildebeest, and its common name is derived from a singular, prominent physical trait. This trait is specifically identified as a very long, shaggy beard that is dark in color and hangs down from the animal's throat area. Although the beard itself is described as dark, the characteristic presence and length of this specific feature below the jawline is what differentiates it and gave rise to its common nomenclature.
