First on the weekend agenda — a bonfire at Camp Shabbona Woods. The last bonfire J and I had been to there was on December 16, 2023, when the Forest Preserve folks had managed to keep both campfire and bonfire going despite a steady and sometimes hard rain.
This time the weather was nearly ideal, and more people showed up. There’s nothing like hot dogs and s’mores over a campfire while nearby it looks like the gates of hell are opening.
As evening closed in, J went on a short group hike. While he was gone I spotted some flying creatures I was sure were bats. When the group returned, they also reported seeing bats. Fires, hot dogs, s’mores, and bats. What more could I ask for?
After a cookout at the Chellberg Farm picnic shelters, J and I headed over to the farmhouse to hear Save the Tunes. I always love a late afternoon walk through these woods with the sun glowing through the leaves and onto the path, and the mostly dry creek bed to the side.
The Perseids never became visible thanks to cloud cover that moved in with the evening, but at least sunset gave off a nice glow and showed off the downtown Chicago skyline.
Miller Woods is part of Indiana Dunes National Park. The Wolverine, Amtrak’s train from Chicago to Pontiac (and back), passes it and offers an opportunity to see ridge and swale topography.
Facebook has many flaws, but it does alert me when events I might be interested in are coming up. A few weeks ago I found out about the world premiere of Octave Chanute: Patron Saint of Flight, at Indiana Dunes Visitor Center. I knew the Chanute name vaguely from the old Air Force base, but I couldn’t have told you then where the base had been located or why it was named Chanute. This sounded like a way to get in a visit to Indiana Dunes, learn something, and spend what might be otherwise a dull winter afternoon, depending on the weather.
The parking lot was unusually crowded, and when J and I walked in about a half hour early, a good-sized group was watching Shifting Sands: On the Path to Sustainability, a documentary on the history of Indiana Dunes and efforts to restore what can be restored. It’s meant to inspire, but it’s also tragic and depressing.
By the time Shifting Sands ended and Octave Chanute was scheduled to begin, the auditorium had filled up, even when extra folding chairs were brought out. Soon it was standing room only.
Simine Short, author of Locomotive to Aeromotive: Octave Chanute and the Transportation Revolution, and young director Paul Nelson introduced the film. I mention Nelson’s relative age because the audience was mostly 50 plus, possibly 60 plus, which disappointed me because I would like to see younger people interested in history. Of course, when I was younger none of my peers would have been interested, either.
Bridge 16, or the Portage Bridge
The presentation began with some technical glitches (flashbacks to every high school A/V club everywhere!), but my ears perked up at the mention of the Portage Bridge, accompanied by a photo I recognized immediately. Through this film, I found out Octave Chanute was the engineer behind the much-loved railroad bridge over the Genesee River at Letchworth State Park in New York.
Known for his bridges, Chanute was called in when the original timber trestle, the longest and tallest wooden bridge in the world when it opened in 1852, was reduced to ashes on May 6, 1875, after a train had passed over (spark?). Chanute’s iron replacement opened only 86 days after the fire. According to Short’s book, the piers were rebuilt and the uprights and girders strengthened in 1880, “making the bridge better than new.”
Although modern Norfolk Southern trains were restricted to 10 miles per hour over the Letchworth gorge, Chanute’s bridge lasted until 2017, when the Genesee Arch Bridge opened. The state of New York declined the offer of the 1875 bridge, the last of which was demolished on March 20, 2018. I’d been fortunate to visit the old bridge one last time in 2015. When I’d found out about the premiere of this film, I’d had no idea it would take me back to perhaps the most iconic of my childhood memories. I remember walking along those tracks with my brother during one of his visits.
But wait! There’s more!
Kinzua Bridge
My ears perked up again at the mention of Kinzua Bridge. I’d found out about Kinzua Bridge State Park when I was looking up Kinzua Dam, another place I’d visited as a child, for my 2015 swing through Ohio, New York, and Pennsylvania.
It turns out that Octave Chanute was behind the original 2,000-foot-long Kinzua Bridge (or Viaduct), built in 1882 at 302 feet above the narrow valley floor. Short calls it Chanute’s “most spectacular bridge.” She adds that the bridge was rebuilt in 1900 “to keep up with the increasing volume and weight of the coal traffic.” Carl W. Buchholz redesigned the superstructure on the original masonry foundation piers.
By 1959 the viaduct failed safety inspections and was closed to commercial rail traffic. Restoration began in 2002, but in 2003 an F2 tornado “tore eleven towers from their concrete bases. Investigators found that the anchor bolts, installed under Chanute’s supervision, had rusted over the past 120 years.” Over time, the materials had failed the design.
After seeing this film, I’m even happier that I had the opportunity to walk out on what’s still standing of Kinzua Bridge and get a look at the remnants resting in peace on the valley floor. Even destroyed, Kinzua Bridge is indeed a “spectacular” sight.
Why Indiana Dunes?
Of course, most of the film was about Chanute’s contributions to flight and relationship with Wilbur Wright (rocky; Chanute was an open source kind of man and Wilbur believed in closely held information). What’s the link to Indiana Dunes? With their lake winds, elevations, and soft sand, the Dunes were Chanute’s choice for safely testing their experiments — the Kitty Hawk of the Midwest.
Epilogue, March 8, 2020
Octave Grill in Chesterton is named for Octave Chanute. Found out they serve a Chanute burger.
Remember the little bird who used to tell you things before anyone else did? One must have told J. that January 5, 2020, was National Bird Day, with a 10 a.m. activity at the Indiana Dunes State Park Nature Center.
Together with several families, we helped to fill the many feeders, logs, and hollow stumps behind the Nature Center with safflower, sunflower, and thistle seeds; peanuts; and other goodies. I was sure the presence of many people clomping around would deter the birds until we went back in, but several hung around in the trees overlooking the feeder area, and the bolder chickadees came in to see what was going on (or to make sure we were doing our jobs).
After breakfast at Third Coast Spice Cafe, a shopping interlude at Molly Bea’s, and a stop at the Indiana Dunes Visitor Center, we returned to take photos and for part 2 of National Bird Day — bird bingo. It didn’t take long to spot a cardinal, a titmouse, and a nuthatch eating upside down. The elusive square was held by the Cooper’s hawk. The staff told us they see one perhaps once a week. That no doubt puts a damper on the feeder activity.
After taking more photos, we settled into the very good little library at the nature center, which has books for kids and books on animals, nature, local history, and art. It’s a gem of a resource which I don’t often see in use.
After I spent more than I should (as usual) at the Schoolhouse Shop, we ended National Bird Day with half-price veggie pizza at Villa Nova in Chesterton. Mmmm. No chicken.
December 8, 2019, at Indiana Dunes State Park Nature Center
I’m a little slow but one day years ago when I saw a woodpecker at Promontory Point I realized there are two in the field guides that look very similar — the downy and the hairy. One is smaller but I could never remember which.
Smaller isn’t a good field sign if you haven’t seen both and you’re not sure of the relative proportions.
On a July 2018 visit to Indiana Dunes State Park Nature Center, two woodpeckers happened to land on opposite sides of the same feeder, facing each other. In that moment, I couldn’t miss the most obvious differences between the two, despite the similarity (mostly) of their plumage.
The downy is quite diminutive when seen across from his larger cousin, the hairy. More than that, the downy sports a delicate stub of a bill compared to the hairy’s railroad spike — the bill is almost the length of the hairy’s head.
Finally I got it. I will not have trouble identifying either again. There are other differences, but that bill is the most obvious. Now I have in mind: “downy=diminutive” — body size and bill.
As a side note, the downy is the one you’re more likely to see at your typical suburban bird feeder. I can’t be sure at this late date, but the downy is likely the one my dad fed with free suet from the local butcher.
According to Audubon, the hairy requires larger trees and is less likely to show up at suburban feeders or city parks. I’ve seen enough of them at the nature center to know that area (and their feeders) suit the hairy just fine.
December 8, 2019, at Indiana Dunes State Park Nature Center
I loved many things about where I grew up, like the bird feeders hanging from the wild cherry trees out my parents’ back window. My mother was exceptionally fond of black-capped chickadees, the clowns among snowbirds. Blue jays annoyed my mother because they drove off the chickadees and smaller birds.
The folks at the Indiana Dunes State Park Nature Center seem to have solved this. The smaller finches and snowbirds gather at a tube feeder, while the blue jays and cardinals share tray feeders with gray squirrels (the red squirrels tend to stay on the ground or on the log trough feeders). That’s not to say chickadees, nuthatches, and titmice don’t use the tray feeders, just not at the same time as jays or squirrels.
As corvids, related to crows, jays leave little doubt as to when they’re in the area. The Nature Center is equipped with outdoor microphones to bring the soothing sounds of running water, leaves rustling, and bird chatter indoors. You can be sitting there in a trance, enjoying the peace and small sounds of nature when:
JAY! JAY! JAY!
You’re jarred to consciousness by screeching that’s already loud and further amplified until it sounds like there’s a blue jay in your ear canal. I’ve been known to fly out of my seat almost as quickly as the smaller birds fly off the feeders.
Except the birds on the tube feeders—they can munch on unbothered. If my parents had only known.
December 8, 2019, Indiana Dunes State Park Nature Center
I’ve never seen a red squirrel in Chicago. Years ago I’d read the bigger gray squirrel dominates and drives them out.
I’ve now seen both species at the Indiana Dunes State Park Nature Center peacefully (more or less) sharing the feeders. I asked one of the staff why they have red squirrels when Chicago (or at least my part of it) doesn’t. She said red squirrels prefer (or need?) conifer trees.
This is where usage of common names is problematic. The red squirrel of northern and central Indiana, Tamiasciurus hudsonicus, is a different animal altogether. Known as “pineys” in Indiana, the red squirrel shares a genus with the Douglas squirrel and Mearns’s squirrel. (Try saying that fast.) When not raiding feeders, these “pine squirrels” feed on the cones of conifers. Wikipedia notes the red squirrel “has been expanding its range into hardwood forests.”
The upshot is I’m not likely to see red squirrels in Hyde Park in the foreseeable future. Through an episode of Urban Nature, however, I learned Chicago does boast a second squirrel species, the fox squirrel (Sciurus niger), which I may have seen and thought was a color variation of the gray squirrel. They’re larger, though. According to Urban Nature, they’re found in areas where gray squirrels fear to tread — where predators like coyotes and feral dogs and cats are more common.
There is another squirrel I’m not likely to see — the nocturnal southern flying squirrel (Glaucomys volans). During a saw-whet owl banding at the Nature Center, we learned the mist nets meant for the owls on occasion trap other creatures, such as bats and flying squirrels. As much as I would like to see a flying squirrel, the researchers would rather not. An ensnared flying squirrel quickly frees itself by destroying the pricey mist net, putting a damper on the evening’s saw-whet owl banding activity. I can almost hear, “Curses! Foiled again!”
Added June 1, 2024: I found out a while ago that flying squirrels appear at Cornell’s Sapsucker Pond Woods feeders. Here are two of them making a midnight snack run. Squee.
December 8, 2019, at Indiana Dunes State Park Nature Center
While at the Indiana Dunes State Park Nature Center watching birds and gray and red squirrels (no chipmunks this time), I noticed a melanistic gray squirrel coming in. In all my years in Hyde Park (40!!! Eek!), I’ve seen only one, in Jackson Park between 56th and 57th Streets. On a visit to my late aunt in NW Washington, D.C., I’d seen several in the neighborhood. According to Wikipedia, there’s a reason for that:
Eighteen Canadian black squirrels were released at the National Zoo in Washington, D.C., near the beginning of the 20th century during President Theodore Roosevelt’s administration. Since their introduction, the population of black squirrels in and near Washington has slowly but steadily increased, and black squirrels now account for up to half of the squirrel population in certain locations, such as the grounds of the Washington National Cathedral.
Wikipedia mentions them in the Quad Cities area of Illinois:
Black squirrels are well established in the Quad Cities area along the Iowa-Illinois boundary. According to one story, recounted in the book The Palmers, they were first introduced on the Rock Island Arsenal Island. Some of them then escaped by jumping across ice floes on the Mississippi River when it was frozen, and thus populated other areas in Rock Island.
I hadn’t seen one at Indiana Dunes or Indiana before. This one looked lighter and more grizzled than other melanistic gray squirrels I’ve seen pictured, so it may have had one copy of a mutant gene vs. two.
Gray squirrels have two copies of a normal pigment gene and black squirrels have either one or two copies of a mutant pigment gene. If a black squirrel has two copies of the mutant gene it will be jet black. If it has one copy of a mutant gene and one normal gene it will be brown-black. In areas with high concentrations of black squirrels, litters of mixed-color individuals are common.
To me, this is the most interesting part of the Wikipedia entry:
The black subgroup seems to have been predominant throughout North America prior to the arrival of Europeans in the 16th century, when America’s old growth forests were still abundant and thick. The black squirrel’s dark color helped with better concealment from its natural predators (owls and hawks) in these very dense and shaded old growth forests. As time passed, extensive deforestation and the hunting of squirrels for their meat and pelts led to biological advantages for gray colored individuals; their light-gray color became advantageous in their newly changed habitat. Today, the black subgroup is particularly abundant in the northern part of the eastern gray squirrel’s range. This is due to two main factors. Firstly, black squirrels have a considerably higher cold tolerance than that of gray squirrels. Secondly, because the northern forests are denser and thus darker, the black squirrel enjoys the advantage of better concealment when viewed from above within this dimly lit habitat.
And after a healthy meal of seeds, it returned to the Indiana Dunes woods whence it came.
