Not all adaptations are physical features like fur, teeth, or flippers. Many animals have behavioral adaptations — things they do that help them survive. One common behavioral adaptation is migration, when animals travel long distances from one place to another. Many birds migrate south for the winter because insects and seeds become hard to find. Monarch butterflies travel thousands of miles from Canada to Mexico every autumn. Each new generation follows the same route, even though no single butterfly makes the entire trip.
Another important behavior is hibernation. When food becomes scarce and temperatures drop, some animals like bears, groundhogs, and bats enter a deep sleep-like state. Their body temperature, heart rate, and breathing slow down dramatically, allowing them to live off stored body fat for months. Other animals don't fully sleep but become less active and eat less — this is called torpor. Some birds, like hummingbirds, enter short-term torpor every single night to save energy.
Hunting and defense behaviors are also critical adaptations. Predators (animals that hunt other animals) use different strategies. Lions hunt in groups called prides to take down large prey. Owls use silent flight to sneak up on mice. Some animals use mimicry to look like something else for protection. The harmless hoverfly mimics the black and yellow stripes of a dangerous bee, so predators avoid it. Baby birds call loudly for food, while other young animals stay silent and still to avoid attracting predators — both behaviors help them survive!
1. What is a behavioral adaptation?
2. Why do monarch butterflies migrate?
3. What happens during hibernation?
4. Explain the difference between mimicry and camouflage. Give an example of each.
Write a definition or draw a picture for each word.
Read each adaptation. Write P for physical or B for behavioral.

Draw one predator and one prey animal. Label at least two adaptations for each that help them in their relationship.
1. Why is migration a helpful behavioral adaptation for birds?
2. How is hibernation different from everyday sleep?
3. Why do some animals hunt alone while others hunt in groups? Which strategy do you think is better and why?
4. Design your own imaginary animal. Give it 3 physical adaptations and 2 behavioral adaptations. Explain how it would survive in its habitat.
1. Behavioral adaptations are things animals do to survive.
2. Migration means staying in one place all year round.
3. During hibernation, an animal's body functions slow down.
4. Predators are animals that are hunted by other animals.
5. Mimicry is when an animal looks like another animal or object.
6. Monarch butterflies migrate to escape cold weather.
7. Lions are an example of animals that hunt alone.
8. Camouflage and mimicry both help animals hide or deceive.
