A piebald animal is one that has a spotting pattern of large unpigmented, usually white, areas of hair, feathers, or scales and normally pigmented patches, generally black. The color of the animal’s skin underneath its coat is also pigmented under the dark patches and unpigmented under the white patches. This alternating color pattern is irregular and asymmetrical.
The piebald condition is an inherited genetic trait. The piebald anomaly ranges from a very slight amount of white hair to almost totally white coats. Unlike true albinos, piebald deer have brown eyes and black hooves. The piebald condition is frequently associated with other harmful physical conditions, including skeletal deformities (e.g., dorsal bowing of the nose, short/deformed legs, curved spine, short lower mandible, etc.) and internal organ deformities. Piebald deer are rare, typically occurring at less than one percent of the population.
