The co-evolution of hummingbirds and flowers has led to unique adaptations in both. Close-up, slow-motion, and real-time video shows the dynamics of hummingbird flight, flower pollination, gnat catching, nest building, and brooding, fighting, and other survival strategies. Students learn how hummingbirds and ecosystems have shaped one another, and about the impact of human activities. They also learn that "survival of the fittest" results from complex phenomena that merit further study.
