    bold warning coloration

    Does this "bold" mean "courageous" or "distinct"? I think it's the latter, but the translation goes the former.

    go33-33 ex) We think of butterfly wings as being colorful, but many are relatively drab on the underside. Some butterflies protect themselves through camouflage-by folding up their wings, they reveal the undersides and blend in with their surroundings. Through this strategy, they become nearly invisible to predators. Some other butterflies are brightly and distinctively colored, but they taste nasty. A bird that eats one of these butterflies remembers the experience-and avoids repeating it. Now other species of butterfly that do not taste nasty mimic the nasty ones. They are born looking like them in color and shape but not taste. Birds and lizards, who have learned to avoid bold warning coloration, leave these imitators alone.

    Re: bold warning coloration

    How can coloration be "courageous"? It seems nonsense, so I'm trying to verify it with native speakers.

    You've made a natural assumption. When a person with a wardrobe full of browns and greys chooses to wear a red jacket, it is a bold choice. The butterfly doesn't have any choice; the 'choice' is an evolutionary one.
