Short-eared Owl

December 23, 2019 – It’s the most wonderful time of the year, that time when winters’ late afternoon skies become active with Short-eared owls swooping, gliding, or perched on a fence post or in a small leafless tree just above the tall grasses of their winter roost. Early mornings and overcast days are also good times to see the owls. Where suitable habitat exists on the restored prairies or along the rural roads of Northeastern Illinois and Northwestern Indiana during those cold winter months, it is during the late afternoon, as the sun retreats towards the southwest, when those delightful medium-sized owls take to the sky in amazing displays of flight. When not chasing each other, in their minor territorial disputes, they search the fields and prairies for prey, occasionally landing on the ground highly alert and watching the other owls flying above. When “The Prairie State” was truly a prairie, before settlements and agriculture claimed the land, the nesting of Short-eared owls was believed to be widespread and numerous on the unbroken grasslands of Illinois and Indiana. Now there are only a few places suitable for nesting in Illinois. Prairie Ridge State Natural Area in Jasper County is one of those areas and it provides 2000 acres of grassland habitat for these ground nesting owls to roost, hunt, and fledge their young. It should also be mentioned that the 2000 acres at Prairie Ridge has nesting Northern harriers and the states only population of Greater prairie chickens. Closer to home, just east of Kankakee, the 8,400 acres of restored prairie and wetlands owned and managed by the Indiana Chapter of the Nature Conservancy at the Kankakee Sands in Newton County Indiana is a great place to observe wintering Short-eared owls, Harriers, and Rough-legged hawks.

Dragons

July 6, 2019 – Summertime here in northern Illinois is the time we find a variety of dragonflies that are using the wetlands and prairies. Healthy ecosystems provide a food source and a breeding habitat for a number of types of dragonflies like the beautiful amber colored Halloween pennant, Eastern pondhawk, Great blue skimmer, Red-mantled saddlebags, Black saddlebags, and many more. One of the largest dragonflies is the Common green darner that is actually a dragonfly that migrates over 400 miles to lay their eggs in the calm backwaters, ditches, and ponds of our area. A research paper published December 19th, 2018 “Tracking dragons: stable isotopes reveal the annual cycle of a long-distance migratory insect” (Hallworth et al), explains “We demonstrate that darners undertake complex long-distance annual migrations governed largely by temperature that involve at least three generations.” It seem unlike birds that travel back and forth and repeat their migration for a number of years, the green darner’s migration requires three generations to complete a full cycle of going north, back south, and back north. Due to their small size, dragonflies can easily go unnoticed by most, but slowing down, especially in those ideal habitats of prairies and wet areas, a fascinating window to some stunning colors and beautiful detail can open to the patient observer with such a variety of these little flying gems.

March 9, 2018 – The light had changed on the prairie as it neared the late part of the afternoon. The sun, now in the western sky, cast a warm glow that saturated the earthy colors at the Kankakee sands. It was like a switch had been thrown when they suddenly appeared, the Short-eared owls were up and hunting! Two of the owls swooped in working together to drive away a Northern Harrier that was gliding low just above the prairie in search of its’ next meal. Two other owls could be seen perched on small bushes that stood above the tall brown grasses to the north. The irregular flight path of the hunting owls had them flying away but quick turns brought them back towards me for a fly by and then away again as they continued their search for prey. A cloud bank above the western horizon quickly narrowed the window of light needed for my camera, but a quick drive though the Nature Conservancy’s Kankakee Sands located 7 more of these remarkable owls. Swooping and banking as the light grew dim the Short-eared owls took over the evening skies at the Kankakee Sands while the Northern Harriers and Rough-legged hawks found their roosts for the night.
