Bird Survival: Fittest Take Flight

Exploring Natural Selection in Birds Year 7 Science Survival of the Fittest

What Makes a Bird Successful?

Think about different birds you know What helps them survive in their environment? Share your ideas with a partner

Vocabulary: Key Terms

Adaptation: A trait that helps an organism survive Natural Selection: Process where the fittest survive and reproduce Environment: The surroundings where an organism lives Trait: A characteristic passed from parents to offspring

What is Natural Selection?

Organisms with helpful traits survive better They pass these traits to their offspring Over time, these traits become more common Less helpful traits become rare or disappear

Darwin's Finches: A Perfect Example

Bird Adaptations for Survival

{"left":"Sharp talons for catching prey\nWaterproof feathers for swimming\nCurved beaks for reaching nectar\nStrong wings for long migrations","right":"Camouflaged coloring for hiding\nLarge eyes for night hunting\nWebbed feet for paddling\nHollow bones for lighter flight"}

Hands-On: Beak Adaptation Lab

Station 1: Tweezers (insect eaters) Station 2: Spoons (seed eaters) Station 3: Straws (nectar feeders) Station 4: Tongs (fish catchers) Test which 'beak' works best for each food type

Environmental Pressures

Food availability affects which traits survive Climate changes challenge bird populations Predators shape defensive adaptations Competition drives evolutionary changes

Survival Simulation Game

Each student gets a 'bird card' with specific traits Environmental challenge cards are drawn Determine which birds survive each challenge Track which traits help survival over multiple rounds

Summary: Survival of the Fittest

Birds with helpful adaptations survive better Natural selection favors successful traits Environment shapes which traits are advantageous Evolution continues as environments change
