For me, most days on the job consist of time in my “office” outdoors—a woodland, prairie or wetland in the Lake County Forest Preserves—with my “clients”—students, teachers, and families interested in learning more about local nature. On those rare days spent plunking away at a computer indoors, the photo above is my view. Recently, this view is bustling with activity, as hordes of ruby-throated hummingbirds buzz around the feeders, bulking up for a long flight south.
As the hours of daylight drastically shorten in November, the miles of our hike along the entire Des Plaines River Trail quickly stack up. The trek south along this stretch of the trail from Route 60 to Route 22 was summed up in the stillness of bare branches that were silhouetted against the sky and reflected back from mirrors of water in the surrounding floodplain forest.

It was a windy, but bright, April 1 this year. I was on a trail at Ryerson Woods with a group of volunteers. Most of our heads were focused downward, inspecting the minutiae of a bloodroot bloom. Then, someone shouted, “EAGLES!” I truly thought the next thing shouted would be “APRIL FOOLS’!” but when we snapped our heads skyward, we saw two ivory-headed eagles swooping back and forth above the trees. No joke!
Many years ago, while running along the Lake Michigan shoreline late on an evening in January, a feathered ghost appeared on top of a flag pole. It was the first time I had ever seen a snowy owl (Bubo scandiacus) and it stopped me in my tracks. This was the spark on that frozen night that lighted my fire of curiosity about birds. This winter, snowy owls have left their Arctic homes in record numbers, causing one of the largest irruptions (sudden increase) in northern Illinois in decades.
Although it seems natural to correlate the arrival of these boreal birds with the extremely cold, snowy winter northern Illinois is having, experts say the motivator is more likely linked to food. On their Arctic breeding grounds, snowy owls feast under 24-hour sunshine. Their food of choice is lemmings, small mammals with an extremely cyclical population. Bird expert Kenn Kaufman explains in a recent Audubon magazine article, that when the lemming population explodes, like it did last summer in northern Quebec, snowy owls have great breeding success, producing large broods of up to 11 chicks. As these chicks quickly grow into juvenile birds, the competition grows for the now dwindling numbers of lemmings. Thus, the young birds get nudged further and further away to find a meal, resulting in them moving to areas that mimic their treeless tundra home, such as the Lake Michigan shoreline.

This past weekend I had the pleasure of hearing Kenn Kaufman, a naturalist and bird expert, speak at the Smith Nature Symposium. He is somewhat of a “rock star” in the birding world. His novel, Kingbird Highway, chronicles a personal adventure hitchhiking around the country at the age of 16 on a quest to find birds—a story that has reached the status of folklore. Many years later, and surely a much longer “life list,” his keynote address at Ryerson Conservation Area focused on warbler migration: the phenomenon of these teeny tiny birds in every hue of the rainbow that travel thousands of miles across entire continents each spring and fall. He presented complicated doppler maps and in-depth scientific research on these migratory dynamos, but by the end of the discussion the focus had shifted to something more simple: the children from his young birders club.
Late that evening, as I settled down with one of his many guide books, Field Guide to Advanced Birding, I was struck by this same theme of simplicity. Kaufman urges folks to slow down and focus not on looking for the birds, but instead to spend time looking at the birds. He stresses getting to know the common birds of an area very well. By doing so, we are well on our way to knowing when a rare bird may enter the scene. This concept brought to mind one of the best places to take a long look at one common bird of Lake County, Illinois: a great blue heron rookery.
Earlier this week, my husband came in from the yard with a mosquito on his forehead. Had it been summer, that little tag-along would never have made it so far—but not in December. In the colder months, critters that are commonplace during the Midwestern summer are often the farthest things from our minds. It always amazes me when the weather has been cold for an extended period, then, at the first sign of warmth, insects seem to magically reappear. Where have they been hiding? How did they survive the frigid air that makes me shiver in my sweater when I’m outdoors longer than a few minutes?
Birding fever hit a high this past weekend in natural areas throughout northern Illinois. Birders flocked in throngs with binoculars strung on their necks like potential Olympic medals and a hope of spotting some of the most coveted migratory birds— wood-warblers. Members of the family Parulidae, wood-warblers are the colorful jewels of migration from the sapphire blue of a cerulean warbler (Setophaga cerulea) to the amber orange of a Blackburnian warbler (Setophaga fusca). Yet, as these birds flit about in the treetops, no color is as visually striking as the lemony-yellow citrine that adorns so many warblers as they pass through our area on a flyway. Once these impish birds reach their destinations (as far as northern Canada for some species) and breed, they will molt their flamboyant plumage and become far less conspicuous, which is why seeing them in the spring is considered such a prize for birders.

Like most of you reading this, my life is busy. Even though I work outdoors in the forest preserves, not all of my nature experiences occur there. Many days I have to take the glimpses of nature where I can get them. On my drive home from work last week, glancing at the “not-so-glamorous” retention pond next to the tollway, I spotted my first hooded merganser of the year. I knew the gang was back, although some of them not for long. This “gang” I’m referring to is the group of migratory waterfowl that show up here in the early spring during migration en route to their final destinations further north. With names like horned grebe, American wigeon, northern shoveler, and gadwall (just a few of the species seen in the past few days at Independence Grove Forest Preserve, here is the complete list), who wouldn’t want to meet this cast of characters?
This time of year is the perfect opportunity to take a peek at some fascinating birds close to home. Continue reading →
