4. According to the reading, warning coloration results when is the concept that animals use the color to alert predators.
The professor explains this concept by giving two examples.
First, he describes that monarch butterfly has a conspicuous marking on its wings. When birds consume this butterfly, they become sick and vomit. Then they realize that they have to avoid eating this butterfly. So when predators like birds observe the butterfly's marking, they do not approach this butterfly.
Second, he describes that blue-ringed octopus uses its bright blue-ring to alert predators when it feels threatened. Even bite from biting this octopus can be fatal to even larger organisms. So when predators recognize the octopus's blue ring, they avoid coming close to the octopus with such color.
These examples demonstrate the warning coloration.

bird입장이 아닌, butterfly의 action에 더욱 포커스가 맞춰주셔야 합니다.
