BIRD MIGRATION HELP, EXPERTS NEEDED!

I am a Dance student in the Colchester area and am looking for help on Bird Migration. We have recently received our A level dance exam paper and one of the questions is to create a dance based on Bird Migration! This topic is very interesting, but us dancers have a limited amount of knowledge of this topic, so we need your help! We want to branch out of the typical areas of research such as websites and learn interesting things as well as facts! If any bird migration experts could kindly help me and my fellow dance students in our research stage by providing us any primary knowledge/research any of you may have, interesting stories and where we should focus our research and what on? Thank you ever so much, any information and advice will be extremely helpful!
