Perhaps it seemed like there was more snow in my youth because I was so much shorter then. I do remember seeing photos of me beside towering sidewalk snowbanks, my snowsuit looking like a cocoon, and a smile on my face. Regardless of the amount, snow adds beauty to the landscape, protects the soil, and gives us opportunities to have fun. I recently saw a quote that was something like “If you choose to hate snow, you’ll spend the winter being unhappy, but you’ll still have as much snow.” Amen.

One of the most fascinating and unusual members of the Wisconsin fauna is the Star-nosed Mole (Condylura cristata). Though seldom seen by humans, this animal is widespread on Woodland Dunes properties, and can be active both day and night, year-round. A unique feature of this species is the star-shaped structure of 22 tentacles which surround the snout. As in all mole species, the animal has very poor eyesight, but uses these tentacles for navigating and finding food such as worms, insects and crustaceans.
The Star-nosed Mole is found throughout much of the northeastern United States and Canada, including most of Wisconsin. The animal is dark brown to black in color, approximately 7 to 8 inches in length, including the 2 1/2 to 3 inch long tail. The front paws are wide and adapted for digging with long, stout claws.
The species inhabits a wide range of moist soil habitats including swamp forest, wet meadow, streams, ponds and lakes. It lives mostly within a network of underground tunnels, pushing up excess earth into mounds that give away its presence. An accomplished swimmer, the species is active year-round and will even forage beneath the ice for its prey during frozen-soil periods.
The tentacles on the snout are the most sensitive touch organ of any mammal, containing over 100,000 nerve fibers in an area smaller than your fingertip. Using this sensitive organ, they can identify and eat food faster than any mammal on earth. They even have the ability to smell underwater, by blowing bubbles of air into the water and re-inhaling them to sniff for prey.
This species is also known to be above-ground more than most moles, and can fall prey to hawks, owls and snakes. Although I have never seen one alive, I have found a number of dead animals through the years. Some believe that certain mammalian predators kill them but leave them uneaten because of a foul smell or taste. At Woodland Dunes, I have seen their tell-tale earth work on Willow Trail, Conifer Trail, Goodwin Road, and on the lawn near the observation tower at the Nature Center.

The other day I heard quite a commotion coming from my backyard. I opened up the door with enough time to witness my nearly 100 pound puppy racing away from a grey squirrel that was chattering at him from the top of our fence. As Gus raced towards the safety of the house, the squirrel flicked its tail at him, angry that a dog was ruining his dinner time at the bird feeder. Like dogs, squirrels use their tails to communicate. Unlike my dog that only uses his tail to knock things off of my coffee table, squirrels use their tails for a variety of really useful things in addition to helping them to communicate.
Squirrels use their tail to help them communicate with other squirrels. What they are trying to say can sometimes be determined by what motion their tail is making.
Warning to other squirrels: squirrels will rapidly flick their tails to warn other squirrels about various threats or bad situations. The threat could be that a predator is nearby, or perhaps the squirrel is warning the others to stay away from the food it found. In fact, a squirrel will even flick their tail in the direction of the predator, to let other squirrels know where the predator is. They are more likely to flick their tails at ground predators because those predators are less likely to be able to catch them while the squirrels are up high. If there was an aerial predator the squirrel is more likely to hide to avoid being seen but will still give off a high-pitched warning call (the high pitch calls are harder for aerial predators to locate) so if you hear a high-pitched call but cannot see the squirrel it could be a sign that they saw an aerial predator (like an owl or hawk) nearby.
Startled: a squirrel may flick their tail if they are alarmed or startled by something, even if another squirrel is not around. This is a warning to the predator (or whatever they deem as a threat) that they see it and will gladly run away if they get too close.
Mating season: during mating season a squirrel will tremble its tail to try and attract a mate.
In addition to communication, squirrels will use their tail for a variety of other things such as:
Balance: Their tails help them balance as they race across tree branches or power lines. As they walk across the narrow surfaces they will continuously move their tail to counterbalance them as they go.
Falling: Perhaps they didn’t balance all that well (which happens) and the squirrel falls from up high… well they are likely to be perfectly fine as their tails act as a parachute to slow their fall. The tail can even be used as a soft crash pad for when they land.
Warmth: Squirrels don’t hibernate, so they are up and about during even the very cold winter months so their tail is used to help keep them warm. When they are in their nest, they wrap their tail around their body like a fluffy blanket. If a squirrel is laying on a tree branch (where it can’t curl into a ball), it will lay flat and put its tails over its back like covering up with a blanket (how cute is that?).
Cooling: Their tail can also be used to help cool them down in the summer. Their bodies are designed to divert blood to their tails which then causes their body to cool down. Because squirrels are constantly on the move, they do not want to overheat, so this feature is critical in helping them avoid capture by predators.
Swimming: Though it is not their ideal situation, squirrels can actually swim! They use their tails to help them steer and stay afloat.
Besides just looking cute and fluffy, the squirrel’s tail helps them survive by helping them warn each other of threats, find love, warm and cool down, balance, and even swim.

It snowed a week ago. It’s probably going to be melted by time Thanksgiving dinner is over. I guess that’s ok, but I love when our sky-sprinkling, earth-decorating snow arrives.
Don’t get me wrong. I’m not a fan of the 30 mile per hour winds on the lakeshore when it’s 10 degrees below zero, but I love my flakes, I love my frost, and I love snow angels.
Although shoveling isn’t considered a good time, snow still has a funny way of creeping in and making us enjoy it. Snow is entertaining – we make angels (my favorite), we catch snowflakes on our tongue, and we write all kinds of songs about snow. Irving Berlin hit the big money when he wrote, “White Christmas” – a dreamy song of yesteryear, reminiscing of glistening tree tops and hand-written Christmas cards. It’s nostalgic and cozy… and all because of snow. (I have yet to find a beach song that makes me feel this way.)
Snow is an element that gets us out there. We cross country ski in the powder. We snowshoe when there is a good base. We snowboard when we’re youthful and have what it takes. Hopeful children and sledding hills beg for this crystal element by the inches. Barring severe storms, such as the six- foot one in Buffalo last week, usually the more snow the better.
We even celebrate birds whose names include the word “snow.” There is a Snowy owl who comes down from the northern parts of Canada during the winter months – appropriately named after its brilliant white feathers. There’s also the Snow bunting, an adorable, white and black, medium-sized bird that sometimes looks like it has caramel drizzled over it. The Snow goose breeds in the Arctic regions of North America and eastern Sibera, but can be found in our area during migration. There are also such birds as the Snowy egret, Snowy Plover, and the Himalayan Snowcock. The Snowy egret has a healthy population and shows up from southern states and Mexico every now and then. The other two; however, are not in our region and have much less of a population to go astray.
A small gift came to me in the mail the other day. It was a field guide to snowflakes. A grade school friend of mine sent it from California. He said he figured I already had it, but wanted me to enjoy it or pay it forward. I’m tickled with this nerdy gift and can’t wait to study the crystal structures.
I heard on the news we’re predicted to have a “normal” snowfall this winter – meaning more than the last couple of years. When it does come, please go out and catch a flake on your tongue. Make an angel. Or hum a bit of “White Christmas.” Whatever you choose to do, let yourself go. Be free. Just like a snowflake.
