Chestnut-sided warbler

Written by Nancy Nabak, Communication Coordinator

There are songs and poems written about spring. Authors wax the beauty, the smells, the sounds…all trying to capture a perfect moment in time when their hearts and minds were lifted beyond an endless season.

I’m no different and I’ve got it bad. Colors are bursting into dark greens, mauve-tinted purples and deep blues. But it’s just not the colors; the smells that go with them are intoxicating. I hesitate to use that word in fear of sounding trite, but in reality it’s true. Last night when I pulled into my driveway, my crab tree blossoms were so fragrant that I skipped my usual routine of going into the house, taking off my shoes, and figuring out what’s for dinner.

Instead, I walked around to my back yard and slowed everything down. I noticed that my Jack-in-the-Pulpits were almost knee-high, that my trilliums were still smiling their snowy white, 3-arrowed face at me, and my sensitive ferns were tenderly leafing out. Nothing dull here. Not in the least.

But eventually, I did notice something dull. It was a thud. The sound was so unusual that it caused me to look up from my bed of blossoms and take notice. Two bright red male cardinals were challenging each other – fighting to the ground in a dull thud upon impact. Cardinal A landed on top of Cardinal B and spread his wings and self over Cardinal B.  After a while, the two untangled, flew up, chased each other around a blue spruce, through tiny branches, and then out into the open again, but always landing near each other.  They continued to challenge each other with calls and encroachments. I watched this go on for hours. My son watched it, too. For hours these two boys had nothing more important to do than show might, defend territory, and let spring instincts drive them.

Back to my intoxicating crab tree, this morning as I was backing out of my driveway, those blossoms forced me to put on my brakes, get out of the car, and trim a couple of small branches before driving in to work. They’re now in a vase on my desk. The office smells like Heaven. I’m pretty sure that if Heaven has a smell, this is it.

And as I work at my desk, writing grants and spreading the word about Woodland Dunes, we’ve got Chimney swifts chittering inside our Nature Center chimney. I’m assuming they’re building a nest to bring another generation of insect eaters into the world. (More mosquito eaters – yay!) Their high-pitched chorus from our inner walls is a treat; we’re so happy they’re back.

Let this be the spring where your senses take you on an intoxicating journey.  Listen to the bird songs in your yard. Find the bright colors of warblers in your binoculars, and breathe in the treasure of scents during this beautiful time of blossoms.

During the late spring, I start to spend more time outdoors around sunset I enjoy this time of day because many animals are heading to bed, yet many are just waking. Part of my job at Woodland Dunes is to monitor an amazing, but very under-appreciated group of animals that begin their day around dusk: bats!

Evening bat monitoring

For the last five years, Woodland Dunes has been surveying bats during the late spring, summer and early fall. For the first four years, we used a special piece of equipment called an Anabat monitoring system. This hand-held system detects and records the echolocation calls the bats produce, which are emitted at frequencies most humans cannot hear. Bats use echolocation calls to navigate and locate food. As we survey, we walk continuously for at least one hour on a pre-determined route. The equipment notes the location each bat is encountered and this information and the echolocation sound files are sent to the DNR. The bat ecologists at DNR identify the bat by the sound files and also create a map of the route walked and where bats were detected.
 
Last year, we were fortunate to receive a Wisconsin Citizen-based Monitoring Partnership Program grant to purchase a different monitoring system to increase our monitoring efforts and further educate the public about bats. The newer system is easier to operate and uses an iPad Mini and an EchoMeter Touch 2, which is a small device that plugs into the port of the iPad. The EchoMeter is able to identify what bat species it detects almost immediately after encountering the bat. This amazing feature has been a valuable education tool.
 
Many people ask why it is important to monitor bats. They are truly magnificent animals that play an important role in our ecosystem. A single bat can eat up to 1,000 mosquito-sized insects in an hour and a pregnant female can consume her weight in insects each night! It has been estimated that bats save North American farmers over $22 billion every year in pest control services. Additionally, many bat species are in trouble. Overall the populations of cave bats are declining at an alarming rate due to White-nose Syndrome. This fungus grows on the face and wings of hibernating bats, causing them to act strangely during cold months and use up precious fat reserves too quickly. It’s estimated the fungus has killed over 6 million bats in eastern North America and some hibernacula (cave or mine where bats hibernate) have seen a 90-100% mortality rate. Monitoring efforts help scientists track White-nose Syndrome as it spreads and gain further understanding of its impacts on bat populations.

Hopefully by increasing our monitoring efforts, we can learn more about how to help these amazing creatures!

Remembering Bernie Brouchoud

This is the time of year that birdwatchers long for.  Right now millions of migrant birds of all kinds are returning to and passing through the area.  As I write, orioles are gulping orange pulp and grape jelly while warblers are singing in the trees. The trees, themselves, are getting ready to blossom.  Despite the hardship of winter, and just three weeks after a blizzard, new life presses on and washes over the land.

It was in this season more than 80 years ago, that Bernie Brouchoud was born.  Bernie was the founder of Woodland Dunes and was the most curious person I’ve ever known. He spent countless hours of his boyhood in Mishicot and Two Rivers exploring the woods.  He taught himself about birds and wildflowers and grew to know them in extraordinary ways.  He befriended local naturalist and bird bander, Winnie Smith of Two Creeks, who wrote this column years ago, and he later attended the University of Wisconsin to study more formally.

Bernie lived an unconventional life, and although his early passion was for natural history, jobs in the field were not easily found.  Bernie always kept nature in his life, however. He was a Fuller Brush salesman, which allowed him to be out on the road where he could keep track of birds.  He ran a gas station that had a bird banding station in the backyard.  He managed a produce department of an A & P grocery store, yet found time to band birds before or after work. 
 
More than 50 years ago he recognized the importance of the big woods between Manitowoc and Two Rivers. This area was full of birds and he banded tens of thousands of them there. He also worked with groups of students in the process.  Bernie talked with others and assembled a group focused on preserving what is now Woodland Dunes. He orchestrated the first land purchase by the non-profit in 1975.  Bernie was the first President of Woodland Dunes Board of Directors, and for more than 30 years, its Executive Director. He received many awards for his work in conservation, including those from the Isaac Walton League, the Wisconsin Society for Ornithology, and the Manitowoc County Conservation Hall of Fame.  But his greatest accomplishment – his wonderful and loving family.

Wanting to learn about bird banding, I first visited the newly created Woodland Dunes in 1975 as a high school student. In the 1980’s, I found a pelican in the West Twin River and decided to stop in the little nature center to find out if they were common. This was the first time I really talked with Bernie one-on-one.  He convinced me that I should put my conservation degree to work and become a volunteer. A few years later I would join him on the staff, part-time. I’m glad he gave me the nudge.

Bernie retired from his Executive Director position in 2004, but remained active in the organization for the rest of his life.

From the first 40-acre parcel of woods purchased in 1975, the nature preserve has continued to grow to the 1,500 acres it is today.  Each year, thousands of school children come to learn and thousands of people visit to enjoy the preserve and its trails.  While Bernie worked single-handedly for a long time, the demands of our education programs and land management have grown to needing six staff people.

Bernie Brouchoud passed away last week.  A man with a great legacy has left a large gap in our community, and there would be no Woodland Dunes without him. Although he is no longer with us in the physical sense, his presence will always be felt and he’ll be remembered.  It’s almost a gift of nature that he passed during this special time of year. It’s as if his spirit was lifted by the beautiful birds he loved so much and carried tenderly on their journey in the sky.

I probably speak for many in saying that I don’t remember such a drastic change in weather in spring over such a short time before. I do remember the opposite during a November of long ago when we went from 70 degrees one day to a blizzard the next, but at that time of year the impact on wildlife was not as great.

I don’t know if birds are hopeful as they make their way north in spring, or are just driven by instinct.  Some move earlier than others, and for those the weather 3 weeks ago was really hard.  A lot of people found robins that perished, others found woodcock, which I assume like robins were unable to to reach the soil and its larder of worms and bugs.  At home we had a small yellow-rumped warbler looking under our eaves for spiders during the storm.  Like many, I put out dried mealworms and raisins for birds, which most seemed to ignore.  I was surprised that cardinals seemed to relish the insects, while robins just looked at them briefly.  Later in the storm I found a yellow-rump sheltered in the garage, and a couple of days later my brother next door had one eating suet at his feeder.  But a few days later, despite the warm-up, he also found one dead in his yard.  Fortunately there were other yellow-rumps foraging in the trees, woodcock in the fields, and robins on our lawns.  Just as with people, life is hard, and those who survive are the strongest and most adaptable.

The silver lining associated with this cloud has been the rapid warm up and south winds that now bring different birds each day.  While we were so recently buried in snow, we’re now putting up oranges and nectar feeders for the orioles and hummingbirds – they are already showing up.  White-throated and white-crowned sparrows are everywhere, along with towhees and thrushes and kinglets and the tropical-wintering warblers and grosbeaks.  Along the lakeshore and other waterways, amazing species of shorebirds are present now and the first pelicans are returning.  Many of our mammals have already borne young, others will soon.

In many ways the ebb and flow of the natural world is like our own.  Even though we dominate nature, our lives are not easy.  Nature; however, is relentless, and the forces that drive the seasons are powerful, and the responses of living things are amazing.  Our recent blizzard seemed catastrophic, but wildlife doesn’t seem to dwell on such things – rather, it seems to pick up the pieces as quickly as possible and continue on.  Watching this gives one the optimistic sense that even huge problems can be overcome. Especially in spring.

Skunk cabbage

It looks like an alien or possibly something that would have been featured in the “Little Shop of Horrors” movie, but it’s not alien. In fact, it’s quite native and great fodder for the curious mind. Skunk cabbage is on the bloom and lighting up my imagination.

I took a stroll on Yellow Birch trail off of Goodwin Road a few days ago and was overjoyed to see skunk cabbage springing up in ephemeral ponds surrounding the boardwalk. This purple-mottled, funky shaped plant is one of our first native flowering plants of spring. The snow-covered cobwebs in my mind shed immediately to realize that winter is done. Spring is breaking through!

And breaking through is exactly what skunk cabbage does. It’s a thermogenic plant, which means it can melt its way through frozen ground via cellular respiration. (It can actually generate temperatures from 27-63 degrees Fahrenheit above the air temperature.) Even though the ground is still frozen, the flower of the skunk cabbage can be successfully pollinated by insects that emerge at the same time.
 
The early pollinators: stone flies, scavenging flies and bees are attracted to the foul odor of the plant; hence its name. The skunk-like smell is noticeable when the leaf is broken or torn, or when in bloom. Its pungent scent may also serve to discourage animals from disturbing the plant.
 
Some animals, such as humans, may have a curiosity that overrides any such odiferous warning. I have one of those animal friends. We’ll call him Mike. When Mike was 17, he was on a mission to eat things that Euell Gibbons was advocating. He read both of his books, “Stalking the Wild Asparagus” and “Stalking the Healthful Herbs.” Mike had tried raw cattail, had made acorn flour, and was ready for skunk cabbage.
 
According to Mike, he cooked the plant as Gibbons recommended. “It smelled like cabbage while it was cooking, yet extremely stinky.” But the horrible smell didn’t deter Mike from giving it a go. After all, he had already experienced more than 30 of Gibbon’s edibles and needed one more. He tried to consume it, but said it was “awful!” (I think Gibbons said the same thing.) He also related that he had a weird prickly sensation in his mouth. (Skunk cabbage is not considered edible raw.) The horrible smell lasted in his house for two days, which did not make his mother happy, Mike remembers with a nostalgic look.
 
As we get out there, start exploring, and seeing what nature has to show us, it’s fun to let curiosity spark our minds. Skunk cabbage is an excellent example of that. This weird looking plant, although warning us not to mess with it, begs some of us to test it. This is a test I don’t need to take and prefer not to be graded on, so I’ll just enjoy taking photos of it from the boardwalk.
