Objectives: Students will: ) Comprehend that birds have physically adapted in relation to their type of food supply. ) Deduce what beaks are most efficient for given foods by experimenting with imitation beaks and given food sources. ) Learn the importance of multiple trials. ) Represent their data with a bar graph.

Using your knowledge of the different beak shapes in your community, and understanding of the steps of natural selection, explain how the change in environment would affect the populations of bird species.
Describe at least three beak variations that could randomly appear and further improve your species' chances of survival when feeding on seeds, worms, aquatic vegetation, and nectar.
Introduction: How are bird beaks adapted to the foods they eat? In this lab, we will simulate a scramble competition (kind of like in the old kids' game, "Hungry, hungry hippos") between six species of birds in six different environments.
Bird Beak Adaptation Lab. Purpose. To learn about the advantages and disadvantages of phenotype variation, by simulating birds with different types of beaks competing for various foods. Background. Hopefully, you recall that Darwin was amazed by the variation in the characteristics of plants and animals he encountered on his journey.
