    The first paragraph indicates that higher temperatures may be the cause of earlier migration - causing us all to think of global warming, and prompting the million dollar question "How warm was it the last few months where they normally spend the winter - especially how much higher than average?". No answer is ever given or even attempted. Please supply us with some actual scientific data.
