in the winter of 2004-2005, great gray owls were recorded moving into minnesota in unprecedented numbers. local news, twin cities' media and the national geographic picked up on this extraordinary event. the reason for this invasion could be the lack of prey species, due to a crash in the populations of red-backed voles — their primary food source; or the presence of a thick hard layer of ice due to intermittent snow melt caused by the effects of global warming. | ||
