    Could migration routes be traced back to where birds evolved in ancient times?

    No expert on this but as winters in Germany are getting warmer and more insects are available as food, more and more species are starting to winter here. Not saying day length is not a factor but food availabilty seems to be a bigger factor for at least some species.
