I posted a message on 28th August saying that my grandson Jamie 12, will be coming from the UK to live in the US for a while and he is fascinated by Hummingbirds. He has a research project at his UK school right now and it is to do with the migration patterns of Hummingbirds. Does anyone know of a source where annual migration predictions and charts might be obtained from? I understand that the American Birding Association does something like this but I am certain that one of you out there will have an answer to my question.
