December 5, 2019 -Recently, on the 18th of November, the people of Barrow Alaska, at a latitude of 71º north, got their last glimpse of the Sun until late January 2020. Over these next few months, winters’ frigid grip will take hold in the extreme for the people and the wildlife above the arctic circle. Those high latitudes will become a dim world of unforgiving temperatures, short days, civil twilight, and darkness. One feathery inhabitant of the north is the Snowy owl, also known as the Snow owl, Arctic owl, and Ukpik in the Inukitut language of the Inuit people that live north of the tree line. Many of these beautiful white owls will move south off of their summer nesting range for the winter, but not all. According to Project Snow Storm, an ongoing research project into the yearly movements of Snowy owls, some of the owls actually move further north onto the Arctic sea ice to hunt through the winter. The second largest and heaviest owl in North America, the Snowy owl lives and breeds on the arctic tundra and spends the winter over a wide range from the interior and southern coastline of Alaska, across the Northwest Territories, most of Canada and south into the northern two-thirds of the United State including the flat agricultural land of Illinois. Some years, here in Illinois, higher numbers of Snowy owls are recorded, a phenomenon known as irruptions. Those record years of snowy invasions average every four or five years with the so called mega-irruptions bringing more owls further south then normal. I usually record a few Snowy owls in our area each year, but last year, 2017-18, I recorded seven and of course many other areas of Illinois saw an increase. Research has proven that an increase in prey animals like lemmings and voles on the breeding grounds of Snowy owls also insures the possibility of a successful nesting season. Irruption years of these white raptors spreading southward from their breeding range in the land of the midnight sun is always exciting and increases the chance encounter to actually witness this large white owl hunting over the croplands of Illinois.
December 4, 2017 – Experts are calling the increased number of sightings of Snowy owls this year a possible irruption as large numbers of these Arctic visitors are showing up in the lower 48. There are reports of sightings here in the Midwest about every day as they continue to spread south out of Canada. I found this beautiful Snowy owl in Iroquois county hunkered down and using the utility pole and the thick grasses around the base to block the strong 27 mph winds that were gusting out of the south Monday morning. Snowy owls move into Illinois every year from the north during the winter months but in an irruption year, about every four years, the increased presence can show that the Snowy owls had a good breeding season and research indicates it coinciding with an increase in their food supply of Arctic rodents.
