The video explains beautifully and in a easy to understand way what birds are going through during migration.So please help them as much as you can during their migration. I will post a article soon what can be done..

We’re in the heart of fall migration right now, so for our Question of the Week we wondered how migration works. How do birds prepare? How far do they go? How do they know where they’re going? This fascinating video answers all those questions and more. It was prepared by students in the Cornell University Naturalist Outreach program, and it’s narrated by a recent graduate who worked closely with us during her time at Cornell. Does it answer your migration questions?
