Snowy Owls lead nomadic lives and travel vast distances from year to year searching for productive feeding areas. Some years, most recently in the winter of 2011/2012, conditions cause them to come south in great numbers.
Get an intimate look at these white owls from the north through video and photographs captured by the Cornell Lab's, Gerrit Vyn.
