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.
