As May comes to end, we’ve seen a dramatic transformation of our landscape. I was out of town from May 12th-20th and was shocked by the changes upon my return! It’s a jungle out there! Everything has leafed-out, the grass is green, and the flowers are blooming. The woods are filled with birdsongs and are wetlands are alive with the chorus of the frogs. It’s a busy time in the animal kingdom; animals are finding mates, laying eggs, giving birth, and/or raising young. Our turtle species are also occupied with this survival need at the moment. Turtles lay their legs on land, so females must take on the dangerous journey of coming out of the safety of the water to dig a nest and deposit eggs into it. Males rarely travel far from the water, but a female may venture up to a mile away from water to find the perfect spot to lay her eggs. This journey usually requires her to face the hazards of cars on roads near our wetland habitats.
A study from a student at Clemson University found a frightening percentage of drivers actually swerve out of their way in order to run over turtles on the road, which is hard for me to even fathom! Why would anyone want to do this? The student, Nathan Weaver, put a very realistic rubber turtle in the road, hunkered down out of sight of the cars, and recorded their interactions. In one of his locations, one out of every 50 cars ran over the turtle and, shockingly, nearly 70% of the cars that hit the rubber turtle did so deliberately.
We’ll find turtles on the roads from now until about mid-summer, but mostly during the month of June. Up here in our neck of the woods, the two turtles that are seen mostly commonly are the beloved Painted Turtle and the more feared Common Snapping Turtle. Snapping Turtles are very large in size and can weigh up to 35 pounds. For some reason, (such as serious damage to your car), people seem to be able to avoid these behemoths, as I rarely see injured or dead Snapping Turtles on the road. Unfortunately, I do see a lot of injured/dead painted turtles on the road, so please be on the lookout for turtles while you are driving!
Why don’t turtles just lay their eggs closer to the water to avoid crossing the road? As it turns out, a female’s decision about where to make her nest can have a huge impact on her offspring! The sex of young turtles is determined by the nest temperature during a particular phase of egg incubation. In Painted Turtles, temperatures above about 83 will typically produce females while temperatures lower than that will typically produce males. Therefore, if the turtle picks a place that has relatively thick vegetation cover providing shade, the soil temperature will be lower and more likely produce males. If she picks a spot that is relatively uncovered, the sun will raise the soil temperature, likely producing female offspring. Snapping Turtles apply the same principle, but backwards; lower nest temperatures typically hatch females, while warmer spots hatch males.
In May, it is not uncommon to find tiny Painted Turtles making their way towards the water. As these turtles do not start laying eggs until May and it takes between 50-80 days for the turtles to develop in their eggs, this is too early for these tiny turtles to be from this year’s clutch. Instead, they are turtles that hatched at the end of last summer or early last fall but did not emerge from the nest. Sometimes, the young hatchlings overwinter in the nest and emerge to travel back to the water early the next spring. Years with cold temperatures and little snow cover for insulation can be devastating to these overwintering hatchlings.
Female Painted Turtles lay between 3 and 20 elliptical (oval) eggs in their underground nests. Female Snapping Turtles lay up to 100, but usually 25-50, spherical eggs in their nests. The difference in shape can be a useful identification clue if you find turtle eggs or eggshells. After laying the eggs, female turtles will not see or care for their young. Now, they are on their own. Unfortunately, most of the eggs will never hatch. Many of the nests will be dug up by a predator, such as a skunk, raccoon, or fox, within the first night or two. Of the eggs that do hatch, more turtles may be lost to freezing temperatures if they overwinter in the nest. When they make the journey back to water, even more will be lost to dehydration, predators, or cars on their pathway.
So what can you do? If you see a Painted Turtle in the middle of the road, “rushing” as quickly as it can to the other side, help a sister out! The best thing you can do for a turtle is to park in a safe spot on the roadside nearby, turn on your flashers, and alert oncoming traffic to the turtle in the road. Let her cross on her own. If you do move a turtle, make sure to put her on the side of the road in the direction she was heading, otherwise, she may try to cross the road again. Make sure to wash your hands if you handle a turtle. If you see a snapper in the road, it is better to leave her where she is, as they have a pretty fierce bite. Some people attempt to pick them up by their tails to steer clear of those snapping jaws, but please don’t do that! It can damage the turtle’s backbone and your well-intentioned rescue mission can end up causing more harm than good! Again, if there is a safe way to alert oncoming traffic to the turtle, it is best to let her cross on her own! If you find a turtle in or near your yard laying eggs, keep yourselves, children, and pets at least 20 feet away. Enjoy watching her from a distance in order to keep her stress level down! Lastly, the best way for you to help is to educate your family and friends about turtles, their awesomeness, and how to protect them, especially during nesting season!
Spring has sprung and we’re all antsy to get outside and enjoy the nice weather. But what to do? Find a bird nest? Observe the bees busily visiting flowers in your garden? Listen to the frogs? Watch your favorite pair of loons out on the lake? Did you know that you can do all these things while providing valuable information to scientists around the world?
Citizen Science Programs use ordinary people – like you and me – who volunteer their time to make observations and share their experiences and/or data. Programs collect this data, which provides way more data than any one scientist or a team of scientists could hope of collecting. This huge data collection can then be used by a variety of scientists, studying a variety of topics, in a variety of locations all over the world!
Let’s back up for a minute.
Phenology is the science of the seasons. It is the study of the biological timing of events in nature as they relate to climate and/or weather. It is something that you probably study quite frequently, and you don’t even realize it! Ever catch yourself thinking “I see open water, I wonder when the ducks will be back” or “Fall is in the air, I bet our maple tree will start to change color soon” or “Brrrr! It’s cold! I bet the pond will freeze over this week.” All of those observations are based in phenology. Continue reading
Last weekend I took a road trip to south-central Nebraska to try to catch a glimpse of the migrating Sandhill cranes, a task I thought would be much more challenging than it proved to be. Once you’re there, they’re extremely hard to miss! I’ve always been fascinated by migration events, and I could have died happy last year after taking a once in a lifetime trip to Africa and witnessing the wonders of the Wildebeest Migration. But I have good news! You don’t have to travel that far to see a spectacular migration event! The Sandhill crane migration was far more remarkable than I could have ever imagined. It’s often referred to as one of the greatest wildlife spectacles on the continent. The sheer number of birds and the noise they produced were both astonishing. I had no idea we had anything like this left in our country. It was beautiful. (Click on an image to enlarge.)
Happy New Year! Did you make your New Year’s resolution yet? We often use this holiday as an opportunity to recommit to living a healthier lifestyle. Unfortunately, overzealous plans for dieting and gym memberships quickly turn into abandoned resolutions. Want a resolution you can commit to? Plan to spend more time in nature! There is an ever-increasing amount of research that provides evidence of the myriad of mental, physical, and emotional health benefits of spending time in nature.
Time spent outdoors increases/enhances:
- Energy levels
- Your mood & self-esteem
- Vitamin D levels
- Physical activity/calories burned
- Mobility in aging populations
- Overall feelings of positivity
- Impulse control
- Academic performance
- Feelings of happiness
- Immune system function
- Memory function & ability to focus
- Natural circadian rhythms (responsible for regulating sleep)
- Critical thinking skills
- Problem-solving skills
- Workout intensity (exercising outdoors is more physically demanding on the body)
- Social skills/relationships
- Motor skill development
- Enthusiasm/engagement for learning
Time spent outdoors decreases:
- Stress, anxiety, & depression
- Seasonal allergies
- Inflammation (the bad kind that contributes to autoimmune disorders, inflammatory bowel disease, depression, & cancer)
- Risk of eye conditions such as myopia, computer vision syndrome, & dry eye syndrome
- Risk of cardiovascular disease, cancer, Alzheimer’s disease, depression, hip fractures, & pregnancy complications
- Aching bones in aging populations
- ADD/ADHD symptoms
- Disruptive behaviors
- Blood pressure & heart rate
- Fatigue & sleep disturbances/insomnia
The best benefit? Getting outdoors and into nature is often free or very low in cost. We are very fortunate to call Minnesota our home. Our state has a high percentage of publicly owned land, providing a multitude of outlets into nature! The Minnesota DNR manages over 5.5 million acres in 67 state parks, 9 recreation areas, and numerous state forests, wildlife management areas, scenic and natural areas, and more. As Minnesotans, we have access to over 1,234 miles of state trails! Federal lands in Minnesota provide more public land resources for us to explore, including Voyageur’s National Park, Superior National Forest (including the Boundary Waters Canoe Area), the Mississippi National River and Recreation Area (MNRRA), the national North Country Trail, national monuments and more. In addition, Minneapolis, followed by Saint Paul, has consistently been ranked the number one city in America for ease of access to outdoor/green space!
Committing to the outdoors is something that will look different for everyone. You can start whenever you want (though considering spring is months away, winter would be preferable), however you want, at whatever level is the best fit for you! If the outdoors is new to you – perhaps simply taking a 15-minute hike in nature is the place to start. Once that feels comfortable, build up from there – a 30-minute walk, a 30-minute walk twice a week, etc. If nature is a familiar setting for you, challenge yourself to something new! Have you tried fat-tire biking? What about going on a snowshoe snow-fari? The opportunities for exploration are endless!

I know the cold temperatures and short days of winter can be a daunting factor to overcome. Don’t let these small obstacles thwart your New Year’s resolution! As the saying goes, “there is no such thing as bad weather, only inadequate clothing”. So bundle up and get outside! In the winter, I leave for work before the first light and head home from the office at sunset. As a result, I’ve learned to love walking on cold winter nights with my furry companion.
A walk in the neighborhood woods in winter can be just as thrilling as other excursions. The cold, fresh air rejuvenates your lungs and awakens your senses; your eyes adjust to the darkness and you find you can see quite well with the moon’s reflection off the snow; your ears strain to hear far-off sounds drowned out in busier months – the hooting of an owl, the distant bark of a dog, or the cracking of trees as they freeze. Our current snow conditions add the thrilling adventure of tracking to your night hike! Click on the photos below to find out what made the tracks. 🙂
So don’t miss the opportunity to begin the year the right way… outside! Bundle up and go! We’ll see you out there!
As winter approaches, we are seeing many changes in our bird populations. Some birds, like robins, have formed large flocks and are slowly moving south. Others, like our juncos, have just recently arrived but are only passing through on their journey from northern Canada to southern Minnesota and beyond. Others who will remain here all winter are busily visiting our feeders.
Birds essentially have two options when it comes to winter: they can migrate or they can stay. If they stay, they need a way to stay warm and a way to get enough food to make it through the harsh winter. Again, they essentially have two options: they can wander widely to find food or they can cache food during times of high food abundance. Owls are a good example of a bird species that stay but wander widely to find food. They have large territories they move around in to search for food. Sometimes, when no food is available, owls will leave their territories and widen their search area. In the last two years, we have witnessed an irruption (a sudden increase) of snowy owls in northern Minnesota as a result of food scarcity in their more northern habitat. Continue reading
Last week, we took a look at how squirrels are tirelessly preparing for winter by collecting and stashing food away for the harsh season. This week, we’re focusing on another MN native that caches food for winter – the beavers! They are the largest rodent in North America. While most adults weigh-in at about 45 pounds, beavers can weigh over 70 pounds! Historically, beaver fur has been important economically (trading), which led to beavers being introduced in other regions of the world. A few years back I traveled to Teirra del Fuego, Chile at the southern tip of the Americas. Beavers were introduced to this region of Patagonia in the mid-20th century in hopes of increasing economic prosperity. However, beavers have no natural predators in Tierra del Fuego and have run rampant ever since, causing millions of dollars in damage to the ecosystem. There is now a widespread campaign to eradicate this nonnative species in this region of Chile. In Minnesota, beavers are not only a native species, but also a keystone species, meaning they play a very important role in their ecosystem as timber harvester, architect, and engineer! Here habitat modification by beavers creates aquatic habitats for many other animals, helps prevent flooding and erosion, and aids in filtering and cleaning water.

This month is known as Binaakwii-giizis, or “Leaves Changing Color Moon”, to the Fond du Lac Band of Ojibwe. The beautiful weather over the first couple days of October made for some breath-taking scenery of brilliant yellows against a bright blue sky and dark blue waters. Soon the yellow of our aspens will be replaced by the golden shimmer of our tamaracks. Enjoy the view now, for by the end of the month, we’ll be greeting the barren landscape of winter.
The animals that remain in our cold environment for winter are busy preparing for the season. Throughout the next month, we’ll focus on three animals that uniquely prepare for winter: squirrels, beavers, and winter birds. We’ll kick off our fall feeding frenzy by taking a look at how squirrels are preparing for the season ahead. Continue reading
Fall has unofficially arrived and with it has come cool evenings, dewy mornings, jeans and sweatshirts, fall harvests, pumpkin spice everything, and yes, the first leaves to change color! This month is known as Waatebagaa-giizis to the Fond du Lac Ojibwe, a name that literally means “Leaves Changing Color Moon”. The brilliant colors of autumn are one of the most beloved phenomena of the season, but do you know why the trees change colors?
During the last few days, I feel like I can notice fall slowly approaching. The decreasing day length and dropping temperatures are a signal to birds (and even some humans!) to start preparing to head south. Despite the misconception that birds don’t like the cold, many birds can survive freezing temperatures, so it’s not necessarily the cold that drives them away. It’s our waning resources. It’s hard to find food – whether that be seeds, worms, mice or something else – when everything is covered in snow. Migration can be defined as a movement from areas containing few resources to areas containing abundant resources. In the spring birds head north in a hurry, following the emergence of insects, prey, and plants that are important to their diet. The Northwoods provides an abundance of insects throughout the summer, which is a crucial source of protein for nestlings. Now, as fall slowly approaches with winter right behind it, many of these resources are beginning to disappear and our local birds have one foot out the door. But how can they fly hundreds, sometimes thousands, of miles? How can they sustain themselves? Their flight? How do they even know where to go? While many aspects of migration still mystify scientists around the world, light has been shed on some of the secrets of migration.
