- A butterfly is a kind of animal
- A bird is a kind of animal
- Therefore, birds and butterflies are kinds of animals

- Birds and butterflies are kinds of animals
- Birds eat butterflies
- If an animal eats other animals for food , then the animal will be the predator
- So, birds are predator to butterflies

- A butterfly is a kind of animal
- A bird is a kind of animal
- Hence, birds and butterflies are kinds of animals

- Birds and butterflies are kinds of animals
- Birds eat butterflies
- If an animal is eaten by other animals , then the animal will be the prey
- So, butterflies are prey to birds

- Birds are predator to butterflies
- Butterflies are prey to birds
- Birds avoid a specific kind of butterfly
- Therefore, birds avoiding a specific kind of butterfly is an example of a predator avoiding some types of prey

- Birds avoiding a specific kind of butterfly is an example of a predator avoiding some types of prey
- A predator avoiding some types of prey is a learned behavior
- Hence, birds avoiding a specific kind of butterfly is a learned behavior

- Learned behaviors are learned over the lifetime of the animal
- A bird is a kind of animal
- Therefore, learned behaviors are learned over the lifetime of a bird

- Birds avoiding a specific kind of butterfly is a learned behavior
- Learned behaviors are learned over the lifetime of a bird
- So, birds learn to avoid a specific kind of butterfly over their lifetime

So, birds learn to avoid a specific kind of butterfly over their lifetime
