Question

which of these characteristics would be included in everyones prototype image of a bird? size color feathers fur

Explanation:

To determine the characteristic in everyone's prototype image of a bird, we analyze each option:

• Size: Birds vary greatly in size (e.g., hummingbird vs. ostrich), so size is not a universal prototype feature.
• Color: Birds have diverse colors, so color is not a universal prototype feature.
• Feathers: All birds have feathers; it's a defining and universal characteristic of birds.
• Fur: Fur is a characteristic of mammals, not birds.

Answer:

feathers
