September 12, 2019 – The House finch is a native of the west with a range that stretches from Oregon south into Mexico and east to the western edge of the Great plains. The House finch is very much at home in desert habitats of the southwest. Today though, after being illegally introduced in the 1940’s in the state of New York, their range has expanded to include most of the the Eastern half of the United states with kind of a gap between the eastern and western populations across the Great plains that runs from Canada south to eastern Texas. The expansion into the eastern United States was a result of escaped finches from the illegal pet trade. The captured House finches from the western United States were sent to pet stores in the east. The House finches were marketed as the California Linnet and the Hollywood finch, but soon failed as caged pets. The finches did succeed as escaped wild birds breeding and expanding their range. The proliferation of House finches along with changes to habitats by humans is believed to be key in the decline of the Cassin’s finch in the west and the Purple finch in the east, two species very similar in appearance to the House finch. The House finch is mainly a seed and fruit eater, when fruit is in season. Flocks can be spotted in Eastern red cedar trees feeding on the fruit in late summer. House finches are social and are common in numbers at backyard feeders, here in Illinois, competing for food with other finches like the Purple finch and the Gold finch.
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.
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 8, 2019 – A wooded area south of Kankakee that appears like a tiny island surrounded by an ocean of agricultural fields becomes a respite for the weary travelers during the spring migration. The trees and understory were alive with a number of species of migrating birds that were taking advantage of the safety of the brushy cover and the good food source of worms and insects that the little woods offered. Some of the birds had selected this spot for the summer and were already nesting in the thicket while others were resting and feeding for their continued trip north.
Yellow-rumped warblers in full breeding plumage were busy searching the tree branches and emerging leaves for insects while in the company of tiny Blue-gray gnatcatchers that were extremely animated as they fluttered from branch to branch. Common yellowthroat warblers were staying among the low branches and shorter vegetation as they appeared and disappeared quickly to and from the waters edge and through the brush. A small Least flycatcher was working its’ way through the branches searching for insects while at times stopping for a rest on a nearby perch.
A Northern water thrush, a small Hermit thrush, and a cautious Ovenbird were using the same territory and could be seen at times moving stealthily across the ground through the shadows of the bushes and trees. A perched White-eyed vireo was removing the wings from a dead Red admiral butterfly, the wing dust and wing parts surrounded the gruesome scene as the beautiful little vireo with impressive white eyes consumed its’ prey.
Baltimore orioles and Rose-breasted grosbeaks flying-about lit up like flickering lights among the softened springtime color tones of the wooded acre. The distant whistles of the male Baltimore oriole were such clear and clean songs that they conjured up a vision of the vibrant colored bird perched and displaying that coal black head and wings contrasted with that beautiful yellow-orange body. A female and male Scarlet tanager were searching the ground for worms and small insects. Scarlet tanagers are long-distance Neotropical migrants that nest in the eastern half of United States and all of Illinois and winters in the tropical rain forests in northern and western South America east of the Andes and as far south as the lowlands of Bolivia.
April 22, 2019 – What are those clear and rich bird songs coming from the tree tops with tones and musical phrases that seem sampled from the songs of other avian species? There it is, perched high in the tree, its’ bill pointing towards the clouds. It is that mimic, the Brown thrasher, with its’ piercing yellow eyes, boldly streaked body and a mostly reddish brown back, tail, and wings that sport bright white and dark wing bars. You better look quick before it darts to a lower perch or down deeper into the understory to search for beetles and worms. Seeds and fruits will come later in the season, it is still the early part of spring and the insects and other tiny invertebrates are the food for now for this melodic courting songbird.
Listen for the male Brown thrasher early in the season when he is on his brushy habitat and his songs are a much stronger proclamation of his territory. After the nesting begins, the songs of the male thrasher are somewhat lower in volume. The Brown thrasher can mimic the songs of other birds with a repertoire of up to 3,000 cataloged sounds, according to Stan Stewart, Wildlife Biologist, Alabama Division of Wildlife and Freshwater Fisheries.
Over the years in the other parts of the country, the Brown thrasher has been known by other names. Fence-corner bird, Sandy mocker, Planting bird, and Brown thrush are a few of the names. The thrasher is not part of the thrush family at all and actually belongs to the family Mimidea. Mimidea is the same family as the Northern mocking bird and the Gray catbird, two other mimics we see here in northern Illinois during the nesting season. The Brown thrasher can be found year-round from southern Illinois, south from east Texas to the Carolinas, and into all of Florida. The thrasher is a short-distance migrant and breeds across most of the northern half of the United States from the Great Plains to the Atlantic and north into southern Canada.
November 12, 2018 – A large 12 point buck, photographed just west of Kankakee recently, displays those tell tale signs that the breeding season for White-tailed deer is occurring in our area. Also known as the “rut”, the mating season for the White-tails really gets in gear by the end of October and lasts through January. This burly buck with his huge swollen neck stands like a stone fence between the doe and the intruder. The explanation for the enlarged necks on White-tailed bucks this time of the year during rut is widely believed by wildlife biologists to be the affects of a surge of the testosterone hormone. The increase in hormones is also believed to cause the aggression and the lack of fear that is a well known behavior of the White-tailed buck during the rut.
October 24, 2018 – A little House wren stops for a moment to look down towards the lower branches of a small leafless bush as it surveys its’ next perch. According to recent reported sightings, reflected in the online eBird species maps of the Cornell Lab of Ornithology, many of the House wrens are moving south, pushed by the strong northerly winds and cold air from the higher latitudes. The House wrens will winter in the southern third of the United States south into Mexico. Of course the little songbirds are still being seen in the area, but in greatly reduced numbers as the migration continues.
October 15, 2018 – A southbound, migrating Palm warbler in its’ autumn drab blends in quite well as it finds the perfect perch to quickly survey the surroundings. The Palm warbler is known for its’ tail-wagging and this one doesn’t disappoint, showing off those bright yellow feathers under the tail. In an instant though, the little bird is off to continue its’ hunt for insects or seeds among the tall, dried vegetation.
October 9, 2018 – A tiny Ruby-crowned Kinglet works its’ way up a dried stalk at the edge of a thicket in search of insects in Iroquois county recently. The little bird, which is only 4.3 inches in length, is making its’ way south where it may winter in the southern half of the United States or as far south as Mexico according to The Cornell lab of Ornithology.

September 27, 2018 – A beautiful and colorful female Yellow-shafted Northern Flicker announced its’ arrival as it landed and perched on the branch of a tall snag in Iroquois county. The flickers’ black bib on its’ chest over a peachy light brown color that is covered with black spots from the chest to the belly, is further enhanced with the bright yellow shafts of the tail feathers and a red bar on the nape of the neck. The Northern Flicker is a large and impressive woodpecker that does feed on berries and seed, but its’ primary diet consists of ants, beetles and larvae that can be found in the ground.
