January 9, 2020 – Here in Northeastern Illinois it has been a warmer, more forgiving winter leading up to the new year, and the relatively mild conditions that we have been enjoying have also continued into early January. Open water, and mostly snow-free fields means that there is easy foraging for both migratory and resident wildlife such as birds, waterfowl, turkey, and deer. Large flocks of wild turkeys can be seen feeding on plant material and the spilled grains from the last harvest in the snow-free agricultural fields, the cautious birds usually not far from the safety of their wooded escape. Much like White-tailed deer, wild turkeys separate into groups depending on the time of year. Young male turkeys, in late fall, form jake flocks after leaving their brood flock. The hens also group up after brooding their young. The adult male turkeys stay in bachelor groups until the breeding season arrives in the spring. March and April is the time that the male and female turkeys are joined together in large flocks and then eventually into smaller breeding flocks that are made up of a few toms with ten or fifteen hens. White-tailed deer also form bachelor groups. The bucks group together throughout the spring and summer months and unlike the turkey bachelors that are made up of mostly adult birds, the deer bachelors are made up of many different ages of males. During the warm summer months the White-tailed bucks are growing their antlers back after losing or shedding them during the winter and after the rut (active breeding time). The new growth of antlers starts in the spring and noticeably start out as velvety nubs. During the time of the bucks antler regrowth, the females or does, are giving birth during the spring and summer. By fall the antlers of the White-tailed buck are fully developed. Some antlers are small and are called spikes. While most are average in size there are a few that are huge and impressive but rarely seen. The White-tailed deer in late fall begin another breeding season. The bachelor groups break up and the bucks go their own way in search of does. The wild turkeys, the toms, the hens, and the jakes are still in their groups waiting for spring and another nesting season.
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.
December 19, 2019 – Gliding low and slow across the agricultural fields and the grassy waterways and prairies here in Northeastern Illinois are the beautiful Northern harriers. Once known as the Marsh hawk, these steep banking, quick stopping, hunting birds are considered here in the United States as “resident to long-distance migrants” According to the Cornell Lab of Ornithology. We see an increase in numbers during the fall migration and into the winter months throughout Illinois. The harriers nest in numbers from Northern Wisconsin north into Canada and Alaska. These ground nesting hawks require large amounts of grasslands or wetland habitats for successful nesting. Some of the harriers winter from just south of the southern edge of their summer range, while others migrate all the way south to Central and South America. The stealthy, medium-sized hawks can be seen flying and hunting across Illinois’s cold sleeping landscape, looking and listening for movement coming from the dried dormant grasses just beneath their silent glide. When the focused hunters detect prey they use their long wings and long tail feathers to quickly turn and stop their graceful forward movement and instantly drop down on a field mouse or vole. The harriers are often seen diving at and chasing away Rough-legged hawks, Red-tailed hawks and even other harriers that get too close to their perceived hunting areas. The Northern Harriers are easily identified as they fly low across fields and prairies, their wings most often in a v-shape, and there is a white rump patch at the top of their long tail feathers. The female harriers and the immature birds are dark reddish-brown and tan, and the male adult birds, slightly smaller than the female, are a light-gray and almost white on some parts of the body, the tips of their wings are black. Often perched on a fence post or sitting in a field with a captured prey, one can get a good look at the feather pattern on the harrier’s face, it has a round appearance and resembles that of an owl. The disk like pattern of feathers on the harriers face is believed to help the hawks hear their prey as they hunt.
September 5, 2019 – Throughout the summer months, in the skies over northeastern Illinois, all one has to do is look up to see those large, soaring, dark colored birds gently gliding in the summer thermals. The wings of the Turkey vultures are slightly, but noticeably, pointing up. The unmistakable dihedral angle or “v” shape of their wings while in flight are much different from other large birds like eagles and hawks. Those birds extend their wings straight out and flat from their body when soaring, and appear more like a sailplane. Even at a distance a Turkey vulture can be quickly ID’d by its’ shape and flight patterns. It is not uncommon to witness large numbers of Turkey vultures perched in an old snag preening and drying their wings in the morning sun. It seems that if one bird spreads its’ wings to warm up and dry out, the other perched vultures quickly follow suit. Soon that old tree full of vultures with wings spread wide begins to take on the appearance of the partially furrowed sails hanging from the foremast of an 18 century brigantine. The birds, with their wings stretched out, slowly and carefully begin to turn and reposition on those sometimes shaky branches as they continue their warming in the early sun drying the nighttime dew from their damp feathers. When the time is right and the their feathers are dry and ready for flight the birds begin to lift off from their roost. They leave, a few at a time, flapping their large wings and climbing upward into a column of the warm rising air to begin their daily search for carrion. Throughout the day the vultures are found in fields and along the rural roads and highways where their keen sense of smell and great vision has lead them to their primary food source, road kill. Most of the Turkey vultures will start moving south late in the year and spend the winter from far southern Illinois on south. In recent years though, with milder winters, there are larger numbers remaining throughout the winter months in central Illinois. The Turkey vultures are some of the first to arrive in numbers here in northern Illinois in late winter for another nesting season.
August 5, 2019 – As we are coming to the end of August one can not help but notice the changes that are happening as another autumn nears and summer contemplates its’ well earned rest. The changes that have been a bit subtle are now upon us. The angle of the sunlight brings an inspiring warm tone to the landscape. The gentle breezes swirling through the forest canopy rustles and rattles the matured leaves allowing us to hear those uplifting whispers of the mighty Cottonwood. We have come to that time of the year where there is a bounty in the northern hemisphere for the avian migrants and those birds that are here year-round. Recently fledged birds, along with the adults, are fattening up for the migration, checking every leaf, stem, and branch for insects and worms. Little Blue-gray gnatcatchers, Warbling vireos, and Chickadees are persistently looking over and under every leaf while they cling tightly to the stems as they feed. Thistle and other seeds, berries, and nectar are available for the birds that are coming south from the higher latitudes as well as the birds that have nested here in Northeastern Illinois.
Prothonotary warblers stand out with their bright yellow feathers and olive-gray toned back and wings while gobbling up caterpillars with amazing success as they pluck them off those woody plants at the waters edge. Goldfinches are on the beautiful purple blooming thistle plants along roadways and on the prairies searching for the high fat and protein rich thistle seeds. Adults and this years’ young Hummingbirds stake out and fearlessly defend, from a good perch, their abundant food source, a large thick patch of Orange Jewelweed surrounded by other nectar giving plants. Some of these travelers will be around for a while feeding and fattening-up and growing strong for either a long or short migration. As the weeks go by though, and those abundant food sources in our area start to wane, the north wind bringing cooler temperatures, many birds will leave our area in a final push and continue south where they will spend the winter in a warmer climate.
August 22, 2019 – What are those little dark colored squawking herons seen perched in the dead trees in and around our wetlands, ponds, and creeks? These wary birds are often seen stalking, with only the slightest of movement, as they inch across the branches of a partially submerged fallen snag in the duckweed covered still backwaters of our river. It is now August and soon the little Green herons will be heading south for the winter. The sightings have most definitely increased recently as the new generation of young Green herons, those feathery squawkers that are the results of a successful nesting season, are fledged and hunting on their own. The crow sized herons are dark colored and appear as silhouettes in the dim lit habitat of a slough, but when they are illuminated by the sunlight the beauty of Green heron is revealed. Their feathers are a rich color of chestnut, dark green, and blue-gray and they have yellow eyes and a dagger like bill that shoots out in the blink of an eye as they extend with great speed their long neck to grab an unsuspecting fish, frog or insect. According to Illinois Department of Natural Resources, the Green herons begin arriving in Illinois in April and nesting occurs from May through early July and the fall migration starts in August.
There have been observations and even videos of this remarkable hunter that have verified that some of these birds have learned to use lures to get small fish to come in close. The Cornell Lab of Ornithology stated, “The Green Heron is one of the world’s few tool-using bird species. It creates fishing lures with bread crusts, insects, earthworms, twigs, feathers, and other objects, dropping them on the surface of the water to entice small fish.” As we are now seeing other species of herons and egrets staging and working their way south as autumn draws near, these little night fliers, those squawking Green herons, will soon disappear from our sloughs and wetlands until next April. The Green heron is considered a medium-distance migrant here in northeastern Illinois and winters along the southern coastal areas of North America, and south into Mexico, and Central America.
August 8, 2019 – Having noticed two large bright green American bullfrogs sitting motionless on some rocky soil east of Kankakee this past week I stopped, reversed and pulled over for a photo. It soon became quite clear why these two frogs sat exposed and away from the safety of their nearby duckweed covered watery habitat when two Black Swallowtail butterflies came fluttering in. The unsuspecting swallowtails, in their wandering flight, glided much too low and close to the patient amphibians, and then in the flash of an eye with an explosive lunge, one of the bullfrogs caught and quickly devoured one of the butterflies. I spent the next hour and a half watching these two ambush hunters and I can say with absolute certainty that these frogs missed more prey than they caught. It seems that the frogs were quite skilled at remaining still for long periods of time as they waited for the next opportunity. However ,when a dragonfly, a butterfly or even a fly caught their attention but landed somewhat out of range, the frogs would give themselves away with their sudden movement as they turned toward the prey or tried to move closer. If the insects came within range the frogs mostly won.
The American Bullfrog has long been celebrated in both dark and whimsical literature, even Mark Twain had his celebrated jumping frog. These large green croaking frogs have inspired poetry, songs, stories and myths that have been shared by the indigenous in their traditions and oral histories and are well recognized in American folklore. The bullfrog has a strong, unworldly song that can grab the attention of even the most heedless. They can jump quick and far, they are absolutely voracious hunters and to the bullfrog all is game if it can fit it in its’ mouth. I know for a fact that there are no night sounds that can make the lonely nighttime fisherman feel less alone than those wonderful guttural songs of the bullfrog from the the dark water edges of ponds, lakes and rivers of Illinois. The American Bullfrog is the largest frog in America and most widely known in Illinois and is native to eastern North America.
July 11, 2019 – Foraging on the ground near a dense wooded thicket or obscured by the shrubs, forbs, and native prairie grasses in its’ northern range, an individual or a covey of 20 or more quail could easily go unseen by a passerby. The amazing and well camouflaged Northern Bobwhite quail is less often seen and more frequently heard when finally its’ presence is announced with that famous clear, rich, whistle that sounds just like its’ name “Bob-White!”. In fact, those most recognized and predictable whistles of the Northern Bobwhite are counted at certain times of the year by biologists, citizen scientists, researchers, and landowners. Using the collected data in set formulas is one method to determine the population of bobwhites on a piece of property. The Northern Bobwhite quail has struggled across its’ range, which is much of the eastern half of the United States including Illinois. Over the years harvest records from the IDNR have shown a sharp decrease in bobwhite numbers from the 1950’s through 2017. A number of reasons for the decline of quail populations in Illinois have been identified. According to a document published by Illinois Department of Natural Resources, “The Bobwhite in Illinois: Its Past, Present and Future”, primitive farming in Illinois actually benefited the Northern Bobwhite quail. Hedgerows, fallowing, and crop rotation provided both cover and food for the quail. Advances in modern intense agricultural practices, the clearing of cover, and the increased use of fertilizers, herbicides, and insecticides has had a negative impact on the Northern Bobwhite quail.
The flat farmland in north-central and east-central Illinois where intense row crop agriculture is practiced has become void of the required habitat for a sustainable quail population. Human expansion has also taken a toll on quail habitat. Areas that once held quail habitat are turned into shopping centers, home sites, and sport fields. Management programs to benefit the quail continue to be a challenge for biologists, the complexity of a fragile species, and the human influence on the Northern Bobwhite quail that has changed a landscapes has left little room for this remarkable bird.
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.
June 27, 2019 – A closGrowing low to the ground and hidden in the spring vegetation on a well drained sandy ridge or a sunny rocky slope, the native Eastern prickly pear cactus, also known as Devil’s-tongue, finally reveals its’ location when those magnificent yellow blooms appear. The Prickly pear can bloom over a few weeks in the late spring through early summer, but each one of those beautiful yellow flowers last but only one day. The blooms, which are great for the pollinators, will soon be replaced by the vitamin rich edible pear shaped fruit from which the cactus gets its’ name. e look at the flower of a Prickly pear cactus showing pollen covering the inside of the bloom.
The fruit, seeds, pads, and spines of the Prickly pear cactus have been used by the indigenous people throughout the ages. The early explorers sometimes found a challenging and painful travel, where there was an abundance of the Prickly pear, as they forged new trails. Wildlife, such as land turtles, ground squirrels and even deer are known to eat the pads and fruit of the prickly pear. Conditions are right for the Prickly pear cactus here in the Midwest where there is still undisturbed habitat on the sandy prairies, sandy savannas, and the sunny well drained open and rocky hillsides.
The Eastern prickly pear is the more common prickly pear found in Illinois but there is also the Brittle prickly pear cactus which is found in the far northwestern county of Jo Daviess and is considered endangered in Illinois. There is also the Big-rooted prickly pear that is also found in Illinois and looks very similar to the eastern prickly pear. The Eastern prickly pear grows from New Mexico, north to Montana and east to the Atlantic and south into Florida according to USDA NRCS National Plant Database. The cactus also is found in far southern Ontario which is at the northern edge of its’ range but is reported endangered by the Canadian Wildlife Federation.
