Birds are a critical part of the natural world. They pollinate and disperse seeds for many plants, and they are effective in rodent and insect control. Additionally, they recycle nutrients back to the earth, helping to balance our ecosystem.
Many people look up at birds and feel inspired. Not only for their freedom to go wherever they want whenever they want, but because of their ability to migrate.
About 4,000 species of birds migrate regularly, and their journey is fraught with peril. Birds have to fly through great discomfort, including pollution, natural disasters, cold, fear, hunger, and exhaustion. If their journeys require traversing large bodies of water or the ocean, they must fly the entire distance without stopping.
