Not exactly birds, but this link has a good summary

http://physicist.org/history/climate/index.html

Bird migration, as it now works, evolved as the result of the end of the last ice age, a period of global warming.

You can add those links if you find some.

Yes Esa, global warming has become an alarming problem for the entire ecosystem, and this is why we must go green in everyday choices we make. I've been a green activist for quite a while now and for this reason with every little thing I do I try not to harm our environment just to give you an example, yesterday I bought some wood blinds made of FSC approved timbers, meaning from trees especially grown for the industry. This way I know that I'm not causing damage to our ecosystem, while still achieving the products I need. Therefore we have the alternatives, we only need to go for them.
