What plumage can the snow goose have?

What plumage can the snow goose have?

• A. The snow goose can have white plumage only.
• B. The snow goose can have blue-gray plumage only.
• C. The snow goose can have either white or blue-gray plumage, both belonging to the same species.
• D. The snow goose has multicolored plumage.

Answer: (C)

Snow geese come in color morphs, meaning individuals within the same species can have different plumages. The two common forms are a pure white plumage and a blue-gray plumage. Both forms occur in wild populations and belong to the same species, with genetics driving which morph an individual shows. So it’s correct to say they can have either white or blue-gray plumage, since both are normal color variants of the same species. The idea that a snow goose would be multicolored or restricted to only one color doesn’t fit how these birds vary in nature.
