March 26, 2020 – Looking out across empty agricultural fields separated by waterways of dried grasses, flowing ditches, fallen fences, and the occasional leafless trees in the small and forgotten gnarly thickets that have somehow been spared the plow, we bear witness to a season in change. The picture before us speaks of a tired and somber late winter that is ready to give up its’ frail but respected hold to a new, strong, and hopeful spring. The spring migration brings temporary visitors that are working their way northward, while wintering birds are gathering and waiting for that call to move north. Some of our resident birds of prey, like Bald eagles, Great Horned owls, and Red-railed hawks, in Northeastern Illinois are already nesting, and some are tending to young. The feathered travelers, those long-distance migrants from the southern hemisphere, are yet to arrive but will stage in our area in the coming weeks resting and feeding before continuing north. Others are patiently waiting for those longer warmer days before moving north towards the high latitudes and a short nesting season above the Arctic Circle. Rough-legged hawks, Snowy owls, and American Tree sparrows are some of the birds that have some distance to travel, and in a month or so, those birds will be hard to find as they eventually disappear from the Lower Forty-eight for the summer. This past week two Snowy owls, only a few miles apart, continued their presence in Iroquois county. A dark morph Rough-legged hawk, another wintering Arctic bird, was hovering over a field hunting in the same area not far from one of the owls. On the first day of spring nine Trumpeter swans could be seen resting in some corn stubble east of the Iroquois river, these great white birds will soon move north into the marshlands of Michigan,Wisconsin, and Minnesota for the nesting season. A small flock of American Tree sparrows have been taking advantage of the remaining seeds on an overgrown lot south of Kankakee while finding safety and insects among the web of thick overgrown bushes and small trees. Spring has certainly arrived and the migration brings hope for new generations of many species and a promise of stability for all creatures on this little planet.
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.
January 18, 2018 – A Snowy Owl was perched at the top of an evergreen last week in Iroquois county and seemed to have set its sights on a Fox Squirrel busy looking for food around the base of a large cottonwood. A small flock of Tree Sparrows and the intended target, the surprised squirrel, scattered and vanished when the owl swooped in. A moment after the failed attempt the owl took to the air and headed to a waterway in the middle of the field. The number of reported sightings of Snowy Owls starting to come in for Illinois have exceeded 100 so far. Those numbers are likely to increase from the encounters yet to be reported. In a small part of Iroquois county my high count for these owls is three but this year it has doubled with six individuals and possibly a seventh. It has been a banner season for these beautiful visitors from the Canadian Arctic, they have brought much excitement across the United States along with much science yet to be understood. Remember, if you encounter a Snowy Owl please respect the owl and keep your distance, do not try to approach the owl just to get a photo, observe from a distance with binoculars or a spotting scope. Snowy Owls have just recently been listed as vulnerable by the Union for Conservation of Nature.
