Crows come home to roost

When I sat down to write this blog, I didn’t have a clear topic in my mind. So, I did what I usually do when I want to think and looked out my office window. Through this window, I can see just the tops of three oak trees which today were covered with crows. I counted more than two dozen with more constantly coming and going. And I knew fall was well and truly upon us. Where I’m located in Galesburg, in West Central Illinois, we are known for trains but in the fall the crows come “home” to...

Pokeweed teaches us to ask questions about the natural world

Pokeweed (Phytolacca americana) is a showy plant that makes you stop and ask questions about it whenever it is stumbled upon - whether in your garden or along a hike. From its impressive height, sometimes up to 10 feet tall, to its distinctive reddish-purple stems - you stop and ask yourself: “what is it?” To me, this is the least interesting question you could ask. By observing this showy species, you can ask more interesting questions that tell you so much more about this plant’s...

Wild songbird illness still undiagnosed

The email came in sometime in May of this year. A colleague in Northern Illinois contacted me with a wild bird concern. A woman had found a dead bird in her yard for a second day in a row and was wondering if something was wrong that she had not heard about.  I gave the standard answer:  If an animal who tends to flock, herd, group, or roost together is sick there is the potential for more to fall ill as well. If a species tends to be anything but solitary, an illness has the chance to...

Nature's Technicolor Dreamcoat: The science of fall color

You feel it, don't you? Sunrise coming later, sunset earlier, and the roller rink of acorns underfoot. The change of seasons is well underway. And just as you are pulling out your flannel shirts, wool socks, and warm gloves the trees and shrubs are also pulling out their fall wardrobe. The vivid reds, rich purples, buttery yellows, and that almost indescribable fiery rosy orange of Illinois' deciduous trees and shrubs are a visual feast! Fall color in the Upper Midwest is so striking some...

Coexisting with snakes: What kinds of gardening mesh are safe for snakes?

Have you placed mesh material in your garden or around the outside of your home? Mesh, whether made from metal or plastic, or natural fibers, can be incredibly useful because it allows air, water, and plants to penetrate while keeping out larger objects. Some folks use it to keep birds off their berry bushes, others may place a mesh fence around their garden to keep deer out. While driving in a construction zone, you may also observe that blankets of mesh are used for erosion control on steep...

The hunt for orange September, searching for monarch roosts

It was early on a hot September morning that I turned into Goose Lake Prairie. I had arrived too early for a program and thought I would spend a few minutes in the picnic area listening to those sweet early morning sounds of nature. And then there it was — an unfamiliar, subtle sound — a strange flutter, repeating...almost like a heartbeat.  I expected to find an injured mourning dove trying to gain traction for liftoff, but no - nothing. I looked up into the trees — elm, maple, oak — only to...

Fall is spider season as orb-weavers spin bigger webs

There's a social media meme that says, “There is no better karate instructor than a spider web in the face.” I don’t know about the karate skills, but nothing makes you swat, rub and dance quite like walking into a web. Just imagine how an insect feels. Growing up in the woods, I have walked through my fair share of webs and while I too, practice my karate skills when I do, I have grown to appreciate these fascinating creatures and their webs. While they go by many names, especially when one...

Scat Chat: What animal droppings can tell us

We call anything an animal leaves behind a sign. It could be a broken branch, a footprint, a scrape on the ground or tree, a nest or other home, their own fur, or even animal parts from their last meal. Of all the signs scattered for our inquiry as to what or why, the scat is my favorite and a most appreciated indicator as to who has been there. You need not have anything but a firm stick from the ground to investigate it fully. The Science of Scatology Scatology, the study...

Prescribed fire as a management tool

As we transition to fall here in Illinois, you may see smoke in the air or see the grasslands or forests burning.  These could be signs of a prescribed fire being conducted intentionally to manage our natural ecosystems.  The use of prescribed fire is increasing throughout Illinois.  To understand why fire is being used as a management tool, let’s take a look at the role fire has played in the development of ecosystems in Illinois.  Fire History in...

A personal run-in with the invasive gypsy moth

My family and I recently traveled out of state to drop my oldest daughter off at a summer college program. We were taking this opportunity to do some camping and exploring of the public lands in the upper Midwest. As we traveled down a forest-lined highway en route to our planned national forest campground, we were astonished that, for literally miles, almost every tree in sight was completely devoid of leaves even though it was in the middle of summer.  Not knowing what was going on, I had to...

Ode to the Opossum

Vacuous dark eyes, scaly rat tail, 50 pointy teeth, and oh, that hiss! What is not to love about the opossum? North America’s only native marsupial gets little respect and often scares homeowners who stumble upon this nocturnal visitor snacking below the birdfeeder, rummaging through unsealed garbage cans, or pacing in the window well waiting to be set free. But opossums are really misunderstood nature warriors. And tell me, what other animal has a ...

Spirals in Nature

Of all the natural shapes, spirals are considered one of the most common in nature. We find spirals from giant galaxies down to the smallest gastropod shells.  Spirals shape who we are in our DNA double helix and appear in weather patterns as in hurricanes. One spiral giving us incredible potential and the other able to take it all away. I find spirals to be the most mesmerizing shape of all the natural possibilities. I trace them with my finger on pinecones, gastropod fossils, fern...

The robins have returned, but did they ever leave?

Spring has sprung! What nature-lover doesn't like to engage in a friendly little competition with their friends and family each year over who sees the first robin? Bird lovers often keep detailed notes year to year comparing when the first robin was seen and hypothesize why they were early or late. I remember one cold, snowy New Year's Day in the concrete and limestone of downtown Joliet, I was shocked to see crabapple trees loaded with robins munching away on the frosty fruits.  Naturalists...

History Let’s back up, pigs (Sus scrofa) are not even native to the western hemisphere so how in the world did we end up with one of the most threatening...

Species Profile - Japanese Stiltgrass

I am sure that most of us are familiar with the concept of invasive species - non-native organisms that are introduced into a new environment and take advantage of the lack of natural checks and balances to run amok and impact our native species and natural ecosystems.  My first introduction to invasive species was when I was a kid, growing up in the southern United States, seeing the invasive vine kudzu swallow entire trees. While we do have kudzu...

Wildlife Babies

Spring is the season of new beginnings. Wildlife baby season in Illinois starts as early as February when great horned owls lay their eggs and frogs begin to call. Coyote pups are born in March and soon a flurry of animals continue courting, mating, and preparing for what will be the next generation of their species.  Every spring, people must battle nature vs. nuture when coming across new offspring. I am not going to tell you to simply let nature take its course (though that is the...
