What is the term for the nose mark on a broken rabbit?

The term for the nose mark on a broken rabbit is referred to as a "Butterfly." This term is used specifically in the context of rabbit fancy, where "broken" denotes a coat that has a combination of colored patches and white fur. The butterfly marking is characterized by its distinct shape resembling a butterfly's wings, typically located on the nose area of the rabbit. It can be an important identification feature that showcases the rabbit's breed standard and overall appearance in showmanship contexts.

The other choices do not accurately represent the nose mark on a broken rabbit. "Star" typically describes a marking that appears on the forehead rather than the nose. "Heart" usually refers to a heart-shaped marking and is not standard in rabbit descriptions. "Spot" may refer to any random mark on the body but is not specific to the nose area and lacks the defined structure associated with the butterfly marking.
