What is a black blue or goose?

A "black blue" or "goose" typically refers to a type of bird known as the "Canadian goose," characterized by its black head and neck with white chinstrap markings. These geese are commonly found in North America, particularly near water bodies, and are known for their distinctive honking calls. They are social animals that often travel in families or large flocks, especially during migration seasons. The term "black blue" is less common but may refer to the coloration of certain birds or animals in a descriptive context.
