July 18, 2019 – The adult Barn swallows are sleek and swift with vibrant colors and long forked tails, they are both elegant and beautiful in flight or perched. The American Barn swallows are long-distance migrants and spend the nesting season in most all of the United State and north into southeastern and northwestern Canada and into southern Alaska. The swallows winter in Central and South America. Barn swallows are seen here in Illinois during their nesting season. Most often they are noticed in large numbers around open farm buildings where they build their nests in the rafters and eaves. They also use large and small bridges where they build their nests in the underneath structure of the bridge supports. The swallows construct their nests out of wet mud and grasses forming them into a half cup shape in the relative safety of the man-made structures or natural shelters like cliff overhangs.
These medium size birds fly up and down the creeks and ditches and across open areas zigzagging in confusing maneuvers as they hunt for insects. The young are brought food, usually large insects, while still in the nest or as fledglings perched together near the nest site. Their little bright yellow beaks all pop open at the same time like little beacons as their heads move in unison following the adult birds as they fly by. The adults seem to know who’s turn it is eat next when they return with a plump insect. Folklore and religious tales relating to the Barn swallow have endured throughout the ages. It is said the Barn swallows bring good luck if it nests on your farm but removing the swallows nest would bring bad karma to the farm. It is also said that the Barn swallow brings us the good news, with their chatter, that summer is on its’ way.
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.
June 20, 2019 – A female Dickcissel with her beak full of nesting material momentarily perches on a plant stem just before dropping down into the thick prairie grasses to continue the work on her ground nest. The ground nest is a large cup consisting of weeds and grasses with the softer material on the interior that will hold the brood. The nest will hold three to six tiny light blue eggs that will hatch in about thirteen days.
Nearby, the male aggressively guards his claimed territory, keeping intruders out that dare to venture too close. The female does all the work of building the nest and caring for the young. It seems that the male Dickcissel’s only job is to guard the chosen nesting territory. The male may breed with other females that are attracted to his perfect nesting habitat after the first female is on the nest according to The Cornell Lab of Ornithology. The Dickcissels arrive here in northern Illinois towards the end of May.
The male Dickcissels claim a territory where they sing practically non-stop from their perch on a tall prairie plant or the limb of a short shrub as they try to entice the females. The persistent songs of these sparrow sized grassland birds are common across the springtime prairies and rural agricultural areas of Illinois. The familiar sounds that echo from this little bird can easily identify the vocalist by this mnemonic pattern of “dick,dick,sizzle,sizzle”.
By November the Dickcissels have gone south to a more hospitable climate where food, grasslands, and farmlands are available during our winter months. The birds will winter in large flocks in southern Mexico, Central America, and Northern South America. If you miss them this year just remember next year near the end of May is a great time to listen for their songs when they have returned to the springtime grasslands and prairies of Illinois.
June 13, 2019 – The color indigo is described as a deep rich blue, and that is exactly what catches one’s eye at the forest’s edge beginning in the spring and lasting through the warm months of summer here in Northern Illinois. The flash of that stunning blue feathered breeder fluttering across a brown, black, and green environment can mean only one thing, that those long-distance migrants, the male Indigo buntings, in their alternate plumage, are here for the nesting season. The breeding range of the Indigo bunting stretches from central Texas north across the Great Plains into Canada, east to the Atlantic, and south into central Florida. The Indigo bunting winters in the southern half of Florida, the Bahamas, Cuba, southern Mexico, Central America and south into northern South America.
The females and immature Indigo buntings show less impressive colors than the breeding males. The females and immature birds are brown and tan, with some black in the wings, and dark broken streaks on a white and faded tan chest extending down the front of the bird. The female shows only hints of that famous blue on their shoulders and tail feathers. These little birds come a long way, about 1200 miles each way, in their amazing migration just to nest here in our area where there is suitable habitat of thickets and brushy wooded space bordering open fields and prairies. While many other migrating birds follow river valleys and other landmarks by day, the Indigo bunting uses the celestial map above for navigation making their magical journey on those clear dark starry nights.
June 6, 2019 – Appearing like ghostly aberrations in the soft morning light of late spring the five beautiful Great egrets were spread out around a pond in southwestern Kankakee county last week. Most were wading in the shallows searching for food, while a few were perched and preening on a fallen snag at the ponds edge. One of these hunting birds focused on something in the aquatic vegetation at the north end of the pond. The Great egret pulled out a large fish that it held in its’ bill for only a short time, and for reasons one can only speculate, the bird discarded the catch and moved on and continued hunting. It wasn’t long before the egrets took to the air, their impressive wings spread wide as they gracefully circled and gained altitude. Having used the pond for the night for resting and feeding, the birds flew northwest continuing their migration towards the nesting colonies on the lakes and in the river valleys.
The Great egret is considered a resident to medium-distance migrant and range widely over the continent, according to The Cornell lab of Ornithology. Many of these birds nest in colonies in the backwaters and wetlands of small and large lakes and rivers like the Mississippi and the Illinois. The Great egrets are in northern Illinois from early April to late October when they, along with a new generation of young egrets, migrate back south for the winter. The Great egret has struggled throughout the years. They suffered major declines of more than 95% from plume hunters for the fashion trade in the late 1800’s and the early 1900’s. The egret population began rebounding as a result of the Migratory bird laws that were enacted in the the first decades of the twentieth century. The birds are considered to be stable today despite the challenges of habitat destruction.
May 30, 2019 – Flycatchers have returned to northern Illinois for the season. They are most often seen perched at the edges of wooded thickets, along rural ditches or open areas near ponds, creeks, and meadows waiting for insects to take to the air. Patiently perched on a tall sturdy dried stem from last years growth or on a limb of a fallen tree, the mostly drab colored little birds can quickly fly off their perch and grab insects in midair or pluck one off a nearby leaf. They detect the slightest movement from a walking or flying insect with their keen vision.
Consuming their prey promptly, the flycatcher resumes focus on their surroundings, watching for prey from a satisfactory random perch. Small crawling and flying insects such as beetles, leafhoppers, and dragonflies are a few of the types of insects that the flycatchers feed on. Some flycatchers, like the Eastern Kingbird, primarily feed on insects early in the season while in their summer range here in Illinois, but wild fruits become part of their diet as this supplemental food source becomes available later in the season. During the months that the Eastern Kingbird spend in the western Amazon basin in South America fruits are a main food source for these birds.
Like many of the other traveling birds we see during the spring migration and during the nesting months here in Illinois, the flycatchers migrate north from the southeastern coastal areas of the United States and southwest into Mexico, Central and South America. While some nest in the United States others continue north into Canada and Alaska, like the Alder flycatcher for example that has a large nesting range and breeds in the area of the Great Lakes in the United States, and most of Canada and Alaska. Some of the more common flycatchers we see during the summer nesting season in Northern Illinois are Eastern wood-Pewee, Great-Crested Flycatcher, Eastern Phoebe, Least Flycatcher, and the Eastern Kingbird.
May 23, 2019 – It is springtime in Illinois and the endangered Upland Sandpipers have returned to the Prairie State for the nesting season. These long-distance travelers make their way back to Northern Illinois in April each year from their wintering prairies of Brazil and Argentina in southern South America. While it is winter here in Illinois, the Upland sandpipers time in South America from November to March is actually the austral spring-summer on the Pampas. The Upland sandpipers nest across the Northern United States from east of the Rockies to the east coast. The sandpipers seem to be more common throughout the great plains of the United State where habitat remains. Their summer range reaches north through the central provinces of Canada and north to Alaska. The sandpipers have become more scarce in Illinois over the years and observations are less frequent as they become somewhat of a rare breeder. There are signs though, that they may be adapting to some agricultural areas, at least in small numbers.
The Upland sandpipers start arriving in Illinois in the middle of April producing eggs from the middle of May into June. They produce three to four in a clutch that have a 21 day incubation period. Both male and female birds take turns on the nest during the incubation. The nests are constructed in depressions in the ground that are lined with leaf litter and grasses and are hidden by grasses arched over the top according to the Illinois Department of Natural Resources. Early season mowing along roadways and intensive farming that removes nesting habitat has a negative impact on this struggling bird in Illinois. From the Upland Sandpiper Conservation Plan (Vickery et al. 2010): The greatest threats the Upland Sandpiper faces are loss and degradation of habitat and the use of agrochemicals on both the breeding and nonbreeding grounds; and loss or degradation of critical stopover habitat.
May 16, 2019 – On their way to the high arctic for the nesting season, those grassland shorebirds, American golden plovers, have been staging in good numbers in parts of the Midwest and have been here in Northern Illinois for the past few weeks. You must look with a careful eye to see these visitors from South America as they blend in quite well in the unbroken agricultural fields in our rural areas. When these well camouflaged little birds, that are about the size of the American robin, are resting in the midday sun they lay flat on the ground in small depressions and are almost impossible to see. These swift flying, long-distance migrants winter on the Pampas of South America from central Argentina and Patagonia south to Tierra del Fuego and we get to see them while they migrate north in the spring.
The plovers start heading north in February, gathering in large numbers in northwestern Argentina. I was able to photograph the the leg bands of one of these birds in September of 2017 near Momence. The bird had been banded in July of 2012 on Bylot island, Nunavut Canada. The Bird Banding Biologist of the Canadian Wildlife Service have two years of telemetry for that particular plover for the years 2014-2015 and 2015-2016 showing two migratory tracks. The spring migration from South America for both northbound trips where it had departed land was off the coast of Chile, south of Peru heading out over the Pacific ocean moving northwest and rounding to the south and west of the Galapagos islands.
The plovers’ path went north crossing Central America over the Gulf of Mexico and entering the United States at New Orleans. The plover followed the Mississippi river valley north, spending time in the state of Mississippi south of Memphis Tennessee. It eventually entered Illinois where it zigzagged across Illinois and Indiana as far east as Indianapolis before working its’ way to Northern Illinois. The plover was just south of Kankakee in Iroquois county where it spent a number of weeks before exiting west out of the state. When the bird finally did leave Illinois, probably in mid to late May, it headed west to the great plains of Nebraska, South Dakota then North Dakota before leaving the United States and moving north into Canada.
The plover continued north and moved out over Hudson Bay across the Hudson strait towards Baffin Island above the arctic circle where it spent the breeding season. After the nesting season, sometime in late July or early August, the plover used a more direct route south. Leaving the arctic heading south across Quebec, New Brunswick, and Nova Scotia the Plover started the long crossing of the Atlantic ocean as it flew non-stop towards South America. Reaching land, the little plover entered South America on the northeast side between Guyana and French Guiana continuing on for almost 3000 miles south to Uruguay where it spent the next six or seven months.
