If you want to see and take pictures of Snowy Owls during the winter in North America you have to travel to Polson Montana. During the summer they scatter over the Arctic tundra in the North of Canada and Alaska. During the winter they are more concentrated in small groups in the northern parts of the US. So the year of 2011-2012 is called the year of the “invasion”. Apparently following a good 2010 and 2011 they go in larger numbers more to the South of Canada into the Northern parts of the US. The unique story of the Snowy Owls  is in This article from Yahoo News and it speaks to the far flung sightings of Snowy Owls this winter.

So this small group of 10 Snowy Owls settled on the edge of Polson Montana. I became a member of their birding form and followed the reports about their numbers and locations.
According to the local experts this is really unique to be able to see them in the frozen fields from so close. I flew to Bozeman and spent few days around Polson.
