TED-Ed: Bird migration, a perilous journey - Alyssa Klavans

The video explores the migration of songbirds from Central and South America to North America during spring. It highlights the challenges these birds face, including physical stress and human-induced landscape changes. The video emphasizes the ecological importance of birds and the threats posed by habitat loss, light pollution, and building collisions. It concludes with conservation efforts, such as reducing pesticide use, creating green spaces, and providing safe habitats, to support bird migration and maintain ecological balance.
