Hitting the Books: Sputnik’s radio tech launched a revolution in bird migration research

“Birds fly South for the winter and North for the summer,” has historically proven to be only slightly less reliable a maxim than the sun always rising in the East and setting in the West. Humanity has been fascinated by the comings and goings of our avian neighbors for millennia, but the why’s and how’s of their transitory travel habits have remained largely a mystery until recent years.
