Why do we study bird populations?

Today, changes in bird populations can tell us a great deal about the impacts of climate change, drought, weather, and habitat change in the United States and around the world. But perhaps the most important reason to study birds is to further our understanding of the ecosystems that support all life on earth, including humans.
