With spring in full swing, we will soon have our full repertoire of avian species present in Winnebago. So between our migrant species and those whom we share a home with all year, we will have a plethora of sightings with this I want to bring your attention to a selection of species of both varieties.


Mallard - Anas platyrhynchos

When one thinks of a wild duck it is nearly certain that the first species they’ll think of is the Mallard. This is one of the most widespread. Common habitats for them include wetlands, rivers, lakes, and park ponds; really anywhere that has water present. There is serious sexual dimorphism present with females being a mottled brown and tan while possessing orange bills and feet. Males on the other hand are more colorful with a brown breast, gray belly, a white collar, iridescent green head, orange feet, and a yellow bill. Both sexes will possess an area of iridescent purple-blue feathers with white fringe, called a speculum, on the wing. Mallards pose a significant threat across the world as they have a unique superpower to be able to successfully hybridize with other duck species, which messes with those species’ gene pools. Mated mallards pair up in the fall and spend their winter together until the female lays her eggs, in which case the male will abandon her so as to not draw too much attention to the nest with his bright colors. Mallards are the ancestors of nearly all domestic duck breeds, save for the Muscovy, and have a long storied history with humans in the form of food, feathers, and pets. You can hear their vocalizations here.



Downy Woodpecker - Dryobates pubescens



We present to you the smallest of North America’s woodpecker species. As stated before it is quite small, being only about 5 - 7 inches tall and having a wingspan of only 9 - 12 inches. This is an important identification feature as they are nearly identical to their large relative the Hairy woodpecker. Downy woodpeckers have a solid white belly with three black lines on their cheek, eyes, and cap. Their wings and tail are black with white spots and white barring respectively. Males possess a red spot on the back of their heads and have more pronounced bristles on their beaks. The birds are year-round residents of the deciduous and coniferous forest of northern Illinois, meaning that you get to see them snow or sun, rain or shine. They are consistent visitors of bird feeders especially those that contain suet even though their diet mainly consists of insects in the wild. Sound-wise they can be identified through either their whinnying vocal call or their steady, rapid drumming that can be heard here.



Red-shouldered hawk - Buteo lineatus    


These birds are probably the 3rd most common species of hawk in Winnebago, following the red-tailed and the Cooper’s. Unlike their large cousin, the red-tailed, they prefer to live in forested areas and wetlands, as well as in suburban areas, instead of more open habitats. They are generalist predators who eat a wide variety of small mammals, reptiles, amphibians, and birds. They will become more commonly sighted in Winnebago as the weather continues to warm as many of the individuals and breeding pairs in our area are migratory and spend their winters in the southern United States. This will be especially true from April to July when they’ll be nesting across the region, including Severson Dells. Their most striking feature is their coloration, notably the reddish-brown feathers that are present on the head, breast, bellies, shoulders, and legs; with the reddish areas on the legs and belly being barred. In flight, they are easily recognizable with heavy black and white barring on the wing and tail feathers. Moreover, the titular red shoulders are more vibrant with the backdrop of sunlight. They are also noticeably smaller than red-tails when perched. Their call is a loud “kee-aah” which they screech in repetition as heard here.


Ring-billed Gull - Larus delawarensis

Their colloquial name of “seagull” might make you believe that they are absent from our continental region, but that name is a fallacy as ‘gulls’ are associated with many of our large bodies of water. One of the most common gulls is the ring-billed gull due to their adaptable diet and their comfort around humans. They can be commonly seen flying over large lakes and rivers in the country during their northward migration in May; though they can be seen year round in Chicago and its suburbs. You might even find nesting pairs in some of our areas, but I doubt they'll be visiting your feeders. Their appearance is quite stereotypical amongst other gulls with a white head and belly, gray wings and back, with a black tail hosting white spots. The most iconic aspect of their look is the black ‘ring’ that runs vertically on the beak of the bird. Adult birds are ludicrously noisy and have a varied repertoire of sequels, squawks, and exclamatory notes. Hear some for yourself here.


Summer Tanager - Piranga rubra

This bird holds the distinguished title of being North America’s only all red bird. Due to the males entirely strawberry colored body, save for their eyes and bill. There is major sexual dimorphism in regards to coloration with females being far from red and instead being mustard yellow with olive wings. They are relatively medium sized songbirds coming in at about 7 inches in length and having a wingspan of about 12 inches. Their bills share the same generalist shape shared by many other birds such as robins, thrushes, and other tanagers, but are a little bit more broad. These birds are quite the rare sight in Winnebago county as we sit on the far northern fringes of their summer breeding range with them preferring to spend their summers directly to the west and south of us. To add insult to injury these birds are often out of sight as they forage high in the forest canopy and rarely come to bird feeders as their favorite food are bees and wasps. Their call is very distinctive with a robin-like song interlaced with the muttering of pit-ti-tuck call as heard here.

“Once you see it you can’t unsee it”
April 22, 2025
From the rugged peaks of the Rocky Mountains to golden desert canyons, the rolling prairies to the ancient, mist-shrouded Appalachian mountains — America is a land rich in many beauties. We are home to the towering redwoods of the west coast, sun-drenched coastlines in the south, and the deep blues of the Great Lakes that collectively hold the largest volume of freshwater on Earth. These wild places offer a kind of quiet that stirs the soul. This vast, varied land is what we proudly call “America the Beautiful.” And on Earth Day, this is the America we celebrate. We scroll through snapshots of National Parks, photos of mountain trails, canyon vistas, tidepools, and wildflower filled prairies. Maybe we've seen these places with our own eyes — maybe we carry them like a dream we hope to one day reach. We’ve all, in some way, been struck by the beauty of this land. As I write these words, I’m sitting at my desk looking out the window into the woodland of Severson Dells, watching the first green buds emerge, listening to the fluting whistles of returning songbirds. How lucky are we to live among such beauty? But that beauty is in danger. Today, mountaintops in Appalachia are being blown apart for coal, their peaks stripped and valleys buried in rubble. Ancient forests in the Pacific Northwest are leveled for lumber, their centuries-old trees felled in minutes. Oil rigs rise like metal skeletons in Alaska’s fragile tundra, while pipelines thread through sacred Indigenous lands and important wildlife corridors. Wetlands that once buffered our coastlines from hurricanes are drained and filled. Prairies, once stretching unbroken across the heart of the continent like an ocean of grass, are disappearing under pavement and plow. Our coastlines are receding. Our coral reefs, once vibrant, are dying, bleaching bone-white. Even here, outside my window, invasive honeysuckle strangles the understory where spring ephemerals once bloomed, and the chorus of birds is quieter than it used to be — a stark reminder that nearly one-third of North American bird populations have vanished in the past fifty years. But this isn’t a new story. Ours is not the first generation to witness the cost of ‘progress’. The tension between beauty and destruction has shaped this nation since the Industrial Revolution. And while the challenges we face today are daunting, they are not insurmountable. Every year, on April 22nd, we celebrate Earth Day – a day that itself was born from a moment not unlike our own. America of the 1950’s and 60’s is almost unrecognizable from the America we know today. In 1943, Los Angeles residents awoke one morning to skies so dark and chemical-laden they feared they were under a gas attack . It was smog. Just 5 years later, a lethal blanket of smog from zinc smelters in Pennsylvania killed 20 people in just three days . The Merrimack River in New Hampshire ran a different color each day , depending on what the local mills were dumping. And in 1969, Cleveland's Cuyahoga River — thick with oil and industrial waste — burst into flames , its smoke billowing four stories high. These weren’t isolated incidents. They were the symptoms of a larger crisis—one brought on by decades of industrial expansion with few, if any, environmental safeguards. At the same time that America was enjoying unprecedented prosperity, it was also polluting its air, poisoning its rivers, and sickening its people. The economy boomed, but the environmental consequences were growing harder to ignore. In 1962, a marine biologist named Rachel Carson published Silent Spring, a book that would become a cornerstone of the modern environmental movement. Carson’s work focused on the effects of chemical pesticides—especially DDT—on ecosystems and human health. She warned of a future without birdsong, where toxins accumulated in the food chain and sickened both wildlife and people. Silent Spring struck a chord. It didn’t just present scientific facts, it gave voice to a deep, growing unease. People were already noticing the changes around them: the absence of fireflies in summer, the increasing number of fish kills in local lakes, the haze that lingered over cities for days. Carson’s words helped connect the dots, and it didn’t just inform, it inspired, and from it spurred the beginning of the environmental movement. By the late 1960s, a wave of activism was sweeping the country. Young people were leading protests against the Vietnam War, civil rights leaders were marching for justice, and college campuses had become hotbeds of political energy. Watching this cultural shift with inspiration was Senator Gaylord Nelson of Wisconsin. A long-time advocate for environmental protection, Nelson saw how the antiwar movement had galvanized young people—and he wondered whether that same passion could be channeled into fighting a different kind of crisis: the growing threat to America’s air, water, and land. His sense of urgency only deepened in early 1969, when tragedy struck the California coast. A blowout at a Union Oil drilling platform off the coast of Santa Barbara spilled nearly 100,000 barrels of crude oil into the Pacific Ocean . Black sludge washed up on miles of pristine beaches. Seabirds lay dying under slicks of oil. Dolphins and seals washed ashore. The air reeked of petroleum for weeks. The images were devastating—and they were broadcast into homes across the nation. Senator Nelson knew the time to act was now. In November of that year, he announced plans for a "National Teach-In on the Crisis of the Environment" —a day when Americans would come together to learn, protest, and push for meaningful environmental change. This name was later changed to Earth Day, and the date chosen was April 22, 1970—strategically placed between spring break and final exams to ensure strong participation on college campuses.  To bring this ambitious vision to life, Nelson turned to Denis Hayes, a 25-year-old student activist. With Hayes’ help, a 7 month timeline, and a shoestring budget of just $124,000, Earth Day sparked an unprecedented nationwide movement. College campuses began planning teach-ins and events. Newspapers picked up the story. Civic groups, churches, and schools joined in. The momentum built quickly—and organically. Within a few months, the Earth Day idea had become a nationwide grassroots event supported by millions of people. Colleges campuses across the country organized “teach- ins”, and major newspapers were writing about Senator Nelson's ideas. Earth Day may have been Gaylord Nelson’s idea, but American citizens made it happen. “Earth Day worked because of the spontaneous response at the grassroots level,” reflected Gaylord Nelson. “It organized itself.” Historian Adam Rome would later call it “the most famous unknown event in modern American history.” On April 22, 1970, an estimated 20 million Americans—nearly 10% of the U.S. population at the time —participated in what remains the largest single-day political demonstration in the nation’s history. People from all walks of life gathered for marches, cleanups, rallies, and teach-ins. The message was clear: the environment mattered, and the public was ready to fight for it. What made Earth Day so powerful was not just its scale, but its unity. The movement crossed ideological lines. It was bipartisan, supported by both Democrats and Republicans. At a time of deep national division, Earth Day reminded Americans that the health of our planet is a shared responsibility—and a common cause. Even more remarkable is that this enormous, coordinated event was pulled off without the tools we rely on today. No social media. No email. No cell phones. Just passionate people, printed flyers, rotary phones, and the belief that change was possible. The success of Earth Day didn’t just move the public—it resonated with leaders in Washington, and led to real change. In just a few years, the United States went from having almost no federal environmental policy to enacting an environmental policy infrastructure strong enough to slow down the era of unregulated industrial sprawl to protect our planet and public health. The success of the first Earth Day led to the passage of some of the most important environmental legislation in American history, including: The Clean Air Act (1970) The Clean Water Act (1972) The Endangered Species Act (1973) President Richard Nixon oversaw the establishment of the Environmental Protection Agency and signed the above landmark environmental laws into effect. In a 1970 speech, Nixon captured the spirit of the moment with a message that still rings true today: “The great question of the seventies is, shall we surrender to our surroundings, or shall we make our peace with nature and begin to make reparations for the damage we have done to our air, to our land, and to our water? Restoring nature to its natural state is a cause beyond party and beyond factions. It has become a common cause of all the people of this country. It is a cause of particular concern to young Americans, because they, more than we, will reap the grim consequences of our failure to act on programs which are needed now if we are to prevent disaster later. Clean air, clean water, open spaces—these should once again be the birthright of every American. If we act now, they can be. We still think of air as free. But clean air is not free, and neither is clean water. The price tag on pollution control is high. Through our years of past carelessness we incurred a debt to nature, and now that debt is being called. ” In the years that followed the first Earth Day, America made progress—rivers stopped catching fire, cities began to breathe a little easier, and wildlife rebounded. But the work was never meant to end in the 1970s. Earth Day is a reminder that the environment is not a limitless resource, and that protecting it requires action, accountability, and cooperation. Fifty five years later we face new environmental challenges, but Earth day is a reminder of what we can accomplish when we come together, regardless of party or background, to protect the natural world we all share. Today, the landmark pieces of legislation that were established in the 1970’s are under threat. The first hit to the Clean Water Act was the U.S. Supreme Court’s 2023 decision in Sackett v. EPA, which significantly narrowed the Act's scope, limiting protections for wetlands and many streams. This ruling has led to a significant weakening of federal oversight. More recently, the EPA has announced significant changes to the Clean Water Act that potentially puts the drinking water sources for tens of millions of Americans at risk. As for the Endangered Species Act, there is a proposed rule change that would limit violations of the Act only to actions that hurt or kill animals. Harming the habitats the endangered animals need to survive would no longer be a violation of the Endangered Species Act, which would open large swaths of land to logging, mining and development that were previously protected. As we all know, if a species doesn’t have the habitat to survive and breed in then it will eventually go extinct. This proposed rule change is open for public comment until May 19 in the Federal Register, so please consider sharing your opinion . Additionally, there is the Zero-Based Regulatory Budgeting To Unleash American Energy Executive Order. The legal community is still trying to figure out just how far reaching this EO is, but it is likely to have a significant impact on a wide range of environmental regulations. These threats to the health of our environment put “America the Beautiful” at risk. The spacious skies, amber waves of grain, purple mountain majesties, and the fruited plain from sea to shining sea are left vulnerable. Now more than ever, Earth Day calls on all of us to act to protect our beautiful environment. Earth Day is now celebrated in over 190 countries. But its roots lie in a time when people refused to accept the destruction of the world around them as inevitable. So, what will you do this Earth Day? Because history has shown us: when people care, when they act together, the world changes. The debt to nature is still being called—and we still have the power to answer. This Earth Day, don’t just celebrate – participate. Plant a tree. Call your representatives. Learn the name of the bird outside your window. Donate to organizations that support our natural lands, our water, and our future. Vote. Teach your children not just to love the Earth, but to fight for it. Talk about climate change, even when it’s hard. Especially when it’s hard. Use your voice, use your art, use your science. Join a local cleanup, start a compost bin, reduce your plastic use. Talk to your neighbors. Talk to your parents. Talk to your children. You can’t wait for someone else to take action. You don’t need to be perfect. You don’t need to do everything. But you do need to begin. Because the Earth doesn’t need more perfect people, it needs millions of imperfect people who care enough to act with intention everyday.
