Weatherproofing Children (and Their Adults!) for Winter
Last week we posted about great local options folks have for winter activities. Part of getting geared up for winter is shifting our mindsets and being prepared. Norwegians have a term that's useful in considering weather-hardiness. It's friluftsliv, which means "free outdoor life." In Norway, there's a saying about there not being any bad weather...only bad clothes!

Winter Trails
Snowmobiling is a popular winter activity in our region, and a segment of Wisconsin's self-funded snowmobile trail system winds its way through the Reserve. A local snowmobile club grooms and maintains the trail from December 15 through March 31, snow cover permitting. Enjoy the Reserve's scenic ridges and valleys by snowmobile, the only motorized vehicle allowed to operate on Reserve lands. Snowmobile enthusiasts are required to stay on the designated snowmobile trail.
Star gazing is an excellent activity for clear winter nights. Visit the Driftless Stargazing Facebook page for frequent updates on what's visible in our local night skies, then bundle up and get out with a thermos of hot cocoa.

Tuning In and Keeping Track: An Introduction to Phenology
If you find yourself noticing, contemplating, and wondering about the subtle shifts and patterns in seasonal happenings, phenology is your friend. There is comfort in marking time and tuning into our natural environment, especially in turbulent times like these, and phenology can offer a great way to do so.
Phenology is a fancy term that means the study of cycles and seasonal natural events. The word is built of two parts: "pheno" (phaino in Greek), which means "to show, to bring to light, to make to appear" and "-logy" of the root "logos," which means "study, discourse, or reasoning." It was first used in a public lecture in Brussels by Belgian botanist Charles François Antoine Morren in 1849.
However, phenological understandings have been fundamental to the human relationship with the land and environment. Indigenous peoples have used phenological knowledge in cultural, agricultural, and ecological practices for thousands of years. Here in Wisconsin, the College of Menominee Nation has recently created a Phenology Learning Path to honor the ways the Menominee have used nature's calendar to mark time and continue to track climate change impacts.
For those of us who might appreciate a less formal approach, phenology in your own local habitat can be greatly rewarding. It can also be a fun activity to do with children. Start small and manageable, and you might be surprised at where this activity will take you in observing natural phenomena.
Here are some ideas to get started:
1. Choose something to observe that's personally interesting and readily available. It could be a bird species that visits your yard, a favorite tree, or a corner of the park with plants.
2. Set a plan to observe at least once a week. Daily would be ideal, but weekly observations will give you a great view of changes.
3. Find out a little more about the thing(s) you have chosen to observe. Species identification is a great first step, and if you can't figure it out by an internet search, reach out to a local naturalist as they love answering questions and sharing information.
4. Create a space to log your observations. This could be a file on your computer or phone, a simple notebook, or a blank calendar square. 5-year journals are easy to create using a template like this and a sturdy 2-inch, 3-ring binder. Since this calendar is organized by day, by the end of 5 years it allows users to see at a glance what was happening on that same date each year.
5. Record your observations and some details about the weather or other important conditions you notice like time of day, activities around your focused area, and any changes you notice. If you have time or the ability to photograph or sketch your observation, this can add to your record.
6. Consider joining with others to share observations. The Nature's Notebook website hosted by the USA-NPN has several campaigns including monitoring bats, pollinators, and pests. Individual data is personally meaningful, but sharing it as a citizen scientist has the potential to create a volume of data that is relevant in tracking change over time.

Animals Toughing It Out: Resisting the Stresses of Winter to be Active, Part 2
Guest post by KVR Instructor, Cathy Chybowski

Animals living
farther north tend to have larger bodies and smaller appendages. A large body loses heat more slowly than a
small body. Shorter appendages radiate
less heat than longer ones. Many animals
living in the north turn white in winter. The obvious advantage is camouflage for both predator or prey. But another advantage is that white feathers
and fur contain more air than pigment so provide better insulation than fur or
feathers with color. In summary, it is
better to be big and white in winter. Think polar bear! It has a large
body, short ears, tail and legs, and white fur. It is perfectly adapted for living in a cold, snowy landscape.
Snow is a
mixed blessing. For small mammals like
voles, it can provide both insulation and protection from predators. For animals like deer, it can make travel
difficult.
The meadow vole, sometimes called a field mouse, spends most of the winter under the snow in a system of tunnels leading to a communal nest. It is an exception to the “better to be big and white” rule.

To
compensate for its small size and brown color, it actually loses weight before
winter in order to reduce its need for food. Because it is an important part of the food
web, it seldom ventures above the snow. Still, foxes and coyotes hear voles moving under the snow, jump up and
down to collapse their burrows, trapping them and then retrieving them. Two to three months before the snow has
melted, still snug and protected, voles begin to reproduce. A young female can mate at one month of age
and produce as many as 17 litters per year with 5 or more young per litter. Look for the tracks of these small mammals on
top of the snow or the quarter-sized entrance holes to their tunnels beneath
the snow. As the snow melts, the topless
tunnels reveal well-traveled runways beneath.
The white-tailed deer is an energy
conservation specialist. Whenever
possible, it does not expend more energy than it takes in. It grows a thick, woolly underfur and an
outer fur with long hollow guard hairs for insulation and it relies on fat
reserves built up in the warm months to fuel its activities in the winter. When the snow is deep, deer yard up and
follow well worn paths to evade predators and conserve energy. Their digestive system changes to accommodate
a change in diet—grazing in the warm months to browsing in the winter months
due to the snow cover. When you are
outside, look for deer browse, tracks, scat, beds, buck rubs, or antlers
usually shed in late winter.

As a group, birds face three obstacles to winter survival: cold temperatures, starvation, and predation. Birds have a higher metabolic rate and a higher body temperature than mammals, therefore making surviving the cold more difficult.The food supply is diminished and often unreliable. Snow can limit access to otherwise available food. Predators are ever present. Small birds like chickadees, nuthatches, kinglets, brown creepers and titmice join mixed flocks. More eyes reduce the possibility of a predator attack and broadens the search for food. Sometimes these flocks even roost together in a tree cavity, bluebird nest box, or other shelter. Some birds like blue jays, chickadees and nuthatches store food for later consumption and many birds frequent our feeders when the weather turns harsh or there is deep snow cover.
The black-capped chickadee is another exception to the “better to be big and white” rule. In order to maintain its body temperature in winter, it requires 20 times more food than in the summer. How do they do it? Among the chickadee’s amazing physical feats is its ability to forage while hanging upside down and moving every which way, foraging for eggs and larvae of insects in bark crevices. Could this acrobatic method be an adaptation for winter feeding when snow covers the tops of branches, chickadees can still gather food from beneath?

Unlike
mammals, birds do not grow extra feathers for warmth in the winter. Instead, they fluff their feathers to trap
more air for added insulation, often tuck their heads under their wings, and
huddle together under an evergreen bough with a snowy canopy.
Aldo Leopold
writes in A Sand County Almanac: “I suspect that in the chickadee Sunday School
two mortal sins are taught: thou shalt not venture into windy places in winter,
thou shalt not get wet before a blizzard.” Apparently a chickadee survives a frigid 16-hour night by doing lots of
little things just right. As these tiny
creatures wake with the sunrise, they begin foraging and this becomes the order
of their day. By late afternoon they are
“bulging with fat” which provides insulation. As the sun sets they lower their temperature as much as 15 degrees,
settling into a nightly hypothermia, fluffing, tucking, and huddling till
sunrise again, when the fat is depleted. Repeat. Repeat every 24 hours; it is a matter of survival. When you are out, listen for the chickadee’s
voice and watch for their quick movements.
The next time you reach to turn the thermostat
up, think about the challenges that animals face for winter survival and some
of the amazing adaptations and strategies they have evolved to deal with them.

How do they do it? Part 1
As the days become shorter and the temperature drops, animals have three options in order to survive: migrate, hibernate or remain active. These strategies along with essential adaptations help animals to survive the cold season.
Migration: An Easy Out?
Migration
can be quite risky. The energy cost of
migration is high and there can be many obstacles along the route. Most animals spend time in a feeding frenzy
prior to migrating. This added fat will fuel their movement to an area with
sufficient food. For hummingbirds, warblers,
flycatchers and other birds that lose their food source with the onset of
winter, migration is a necessary risk. Large
bodies of water, a changing food supply, predators or hunting can make the trip
challenging.
Did you ever
wonder why it is mostly birds that migrate? Why so few mammals? According to
Peter Marchand in his book, Life in the
Cold, a mammal would expend ten times more energy moving a given distance by
running than would a bird of equal weight flying that same distance. Bats and caribou are exceptions. For more information on bats and insects that migrate see a previous post I shared in August.
Hibernation? Dormancy? What is the difference?
Dormancy is
one of the three strategies animals evolved for winter survival. It is a period of inactivity in which an
animal’s bodily functions are slowed down. By definition, hibernation is an extreme form of dormancy. Woodchucks, bats and jumping mice are among the
few mammals in our state to hibernate.
As an
herbivore, the woodchuck’s life is centered on the availability of plants. Feeding heavily during late summer into fall,
it accumulates thick rolls of body fat and then retires to its burrow usually
by the end of October. While hibernating,
its heart rate drops from 75 beats to 4 beats per minute, its body temperature
drops from 90 to 38 degrees, and it breathes once every 5 to 6 minutes. If the woodchuck can maintain this state of low
metabolism for several months without freezing to death, it will usually emerge
from its burrow during the first week of March (not like Punxsutawney Phil on Feb.
2).
There are
degrees of dormancy, from the true hibernation of the woodchuck at one extreme,
to the deep sleep of bears and chipmunks, and to the short term sleep of skunks,
opossums and raccoons. In all forms of
dormancy, the metabolism slows down in order to conserve energy at a time when
food is scarce.
Research
shows that the black bear does not hibernate; its body does not undergo the
drastic changes of a true hibernator. In
order to prepare for its deep winter sleep, bears spend the fall in a feeding
frenzy putting on several inches of body fat and growing a thicker fur. While in the den, the sow gives birth to 2-3
cubs which do not hibernate either. During
this state of dormancy, the bear does not eat or drink, it does not produce
waste and it does not lose bone or muscle mass despite the lack of exercise. How do they do it? These
unique adaptations are of interest to medical science. There is more to learn
about black bears—how is it that they can survive a 5-month rest and fast and
emerge from their den with a 99% survival rate?
Apparently there are few people willing to crawl headfirst into an
active bear den in the winter to see just how cozy everything is in there!
Chipmunks
spend much of the fall collecting seeds and nuts for storage in their underground
burrow where they spend most of the winter in dormancy. The stored food gives them the option of waking
and being active for a time; I was surprised to see a chipmunk out and about
during a January thaw. No true
hibernator could do this.
Snakes, cold-blooded reptiles, generally hibernate in dens or burrows of other animals, sometimes in groups of mixed species. These are called balls of snakes and it is an amazing thing to see in the spring as these reptiles emerge from their hibernaculum. I witnessed dozens of garter snakes emerging this way one time in southeastern Wisconsin. I happened to be in the right place at the right time.
Stay tuned for Part 2, Animals Toughing It Out, in the weeks to come!

Risk and Play
The Kickapoo Valley Forest School Leadership Team and Governance Council members recently attended a professional development training on risk and play in early childhood with Ross Thompson, M.Ed., an early childhood educator and teaching specialist. Ross shared some important perspectives and considerations for our team as we build the culture of forest schooling in our region. We have a few highlights that we'd like to share with our outdoor learning community.
When it comes to defining risk and play, everyone has their own internal risk calculator. As Ross pointed out, "Risky play depends on who is playing and how they feel." One person may think climbing a tree feels risky, while another person may think speaking out loud in front of a group feels like a big risk. For those of us who work and care for children, considering risk from the standpoint of how we personally view risk is an important first step.
How did you play as a child? What experiences did you have that involved risk for you? Were they physical, social, emotional?
As we consider how our own experiences inform how we work with children, it's important to understand that our concern for the risks of a particular situation may be tied more directly to our own experiences than to the reality of our children's experiences.
Creating an environment where children can safely explore is essential to building strong bodies and critical thinkers. When the environment is controlled to eliminate any or all risks, children may lose some of their ability to weigh, ponder, and consider their actions and decisions.
This doesn't mean that anything goes! In fact, it requires the adults in a caregiving environment to be vigilant and engaged in assessing risk but to do so in collaboration with children. Forest schooling is an amazing opportunity to provide children with natural risk-taking opportunities through lots of opportunities to watch, try, practice, and master many things that might be considered too risky in other learning environments.
For example, many children love to climb and experience height. Rather than telling them it isn't safe to climb a tree or to rely on the common refrain of, "Be careful!" how might we help them consider the finer points of climbing? We could try asking questions like,
"How can you check that the branches will hold you?"
"What's your plan for climbing down?"
Another important point Ross shared is that while risky play often challenges our comfort zones, it should never be dangerous, terrifying, anxiety-provoking, or forced. Children thrive in environments that allow them to take their time and approach a challenge on their own terms. For some children, this might mean watching other children for an extended amount of time before feeling ready to try. Ross shared a great example of a variety of stumps placed in a learning space. Some children feel ready to jump off the tallest stump, and others need lots and lots of practice on the lower stumps. The benefits of having multi-age groups exploring and learning together reinforces the need for some children to play with more risk, and others to watch and observe on their own time.
During our training session, we learned more about how play that involves risk helps develop motor skills, social and emotional frameworks, creativity, and cognitive capacity in young children. We look forward to sharing more about how risk, play, and forest schooling intersect at an upcoming KVFS Virtual Roundtable event on November 17, 2020. Visit our website at kickapoovalleyforestschool.org for the link.

Outdoor Learning Highlight: La Farge Schools
Outdoor Learning Highlight: La Farge Schools
This fall our current context has highlighted the benefits of outdoor learning in new ways. For La Farge Schools students and teachers, incorporating the natural world into academic pursuits is nothing new. Inspired by our beautiful surroundings, LFS teachers frequently make opportunities for students to apply new concepts within our local context.
Recently, our preschool teacher, Mrs. Greenwood, took young learners outside to collect leaves, which they glued onto a line-drawn L. These “L is for Leaf” pages will be combined with other letter/contextual item pages to make a real-world alphabet book for each child.
High School Agricultural Education: Natural Resources
Mr. Fowell regularly visits the La Farge School Garden to plant and harvest with his agricultural science students, as well as to identify weeds. Additionally, he and his classes often travel to the nearby Kickapoo Valley Reserve for class-embedded activities such as bird identification, duck house maintenance, pheasant release, tree identification, and more.
High School Social Studies
History teacher Amy Lund regularly has her students practice outdoor surveying, and her classes go on walking tours of the town. As a part of her Local and/or Wisconsin History courses, she takes students on walking field trips of the local cemeteries and frequently relies on the expertise of local historian Brad Steinmetz pictured below with students this week on a visit to the Kickapoo Valley Reserve dam site.

Fall Bird Migration: Sighting, Care and Feeding
Guest post by Barb Duerksen, KVR Instructor
It’s fall and birds are on the move. Cold weather means fewer insects, so the
birds that depend entirely on insects for staying alive must migrate–they fly
south to find enough to eat.
October and November are exciting months for people who enjoy
seeing birds that are flying in from farther north. Some are species that we can find only during
the time of migration.
The Ruby-crowned Kinglet is a migrant that I’ve seen along
the roadsides recently. They are
olive-colored with white wing bars and a white eye ring. They are small and energetic, flying quickly
through the shrubs, weeds, and trees, searching for food and flicking their
wings almost constantly. In fall the
kinglets are quiet, except for a soft two-noted “jidit” call. The ruby-colored spot on top of the male’s
head is usually hidden in fall. When
they come back through in the spring, the males display that bright red spot,
and sing a sweet warbly song. (Listen to
the song and call here by clicking on the Audio button.)
Most Kinglets will be gone by the end of October. They will spend the winter in the southern
United States and Mexico.
Waterbirds are another group of birds that migrate. They live on or near water, so when it gets cold enough for the water to freeze, they fly south to warmer places. Late October through November is a good time to find geese, swans, and many different species of ducks on ponds and rivers. Tundra Swans are huge white birds with long necks that nest in the far north Arctic tundra. When the weather turns cold, many of them fly south and east, some stopping at resting places like the Mississippi River for a time while they tank up for the rest of the flight. Many spend the winter in the Chesapeake Bay area on the east coast. Goose Island and south along the Mississippi River are good places to find hundreds of these swans in November and sometimes into early December, depending on when freezing temperatures arrive. They call constantly during migration, a high musical “hoo hoo” sound. When you hear that, look up, and you’ll see a flock of big white birds heading south east. Sometimes they migrate at night. (Listen to their call here by pressing the Audio button.)
The birds that can stay alive eating seeds don’t need to
leave when the insects disappear. They
can usually find food all winter. These birds stay here year-round and are appropriately called
resident birds. Black-capped Chickadees, White-breasted Nuthatches, cardinals,
Blue Jays, goldfinches, some sparrows, and many of the woodpeckers are
residents who stay here through the winter. Some birds like Dark-eyed Juncos and Purple Finches fly here from the
north and stay for the winter. Putting up
a bird feeder in the yard is a good way to enjoy the familiar birds and learn
about the new species that arrive for the winter. Birds do have a harder time finding food when
there is lots of snow on the ground and it gets very cold. It is important when
there is nasty weather to keep the feeders full.
Here are some things to consider when you set out to feed birds:
Placement: Keep the feeder within 3 feet or farther than 30 feet from your window to avoid birds crashing into the window.
Cover: Put the feeder near some cover, so the smaller birds have a place to hide when predators come along. If you put a post in the ground near the feeder now before the ground freezes, you can tie your used Christmas tree to the post
Sanitation: Keep your feeders clean so birds don’t get diseases.
Safety/Predators: If you live where there are lots of outdoor cats, it’s really not a good idea to put up a feeder.
For more information about feeding birds: Visit Cornell Laboratory of Ornithology’s All About Birds site.
What to feed the birds? A simple way to start is to put out black oil sunflower seeds and a suet feeder. Most of the birds we have here in the winter like the sunflower seeds. Woodpeckers especially like suet. You can buy suet blocks at the feed stores, or raw suet from a meat locker. You should only use the raw suet when the weather is cold, as it can get messy and turn rancid in warn weather.
Here are some birding activity ideas to inspire you to get out as we move through the fall season.
- Spend a little time outdoors on a walk or sitting still. Listen for bird calls. If you hear chickadees, look nearby for other species. Sometimes migrant birds follow the chickadees on their feeding routes.
- After the leaves are gone and before there’s snow on the ground, the world can seem drab and gloomy. Maybe it’s time to celebrate drab. Bundle up, go out, find 10 things that you would consider drab, and take another look.
- Spend some time learning about Audubon's 121st Christmas Bird Count that will be conducted between the dates of Monday, December 14, 2020 through Tuesday, January 5, 2021. This is a great way to get involved in citizen science.
