Because the beaver isn't just an animal; it's an ecosystem!

Category: Beavers and Bears


I’ll be completely honest. I don’t love all the footage and studies from Voyageurs about wolves stalking beavers or doing everything they can to eat beaver mcnuggets. But they do some amazing trailcam work. And this is one of the best I’ve seen.

A Beaver Dam: Fall to Winter

Here it is, the sequel to “A Beaver Dam: Summer to Fall.” It features more footage from a trail camera on a beaver dam at Kabetogama Peninsula in Voyageurs National Park.

The purpose of the camera was to confirm the area was a border for the territories of two wolf packs — the Nashata Pack and the Shoepack Lake Pack. The Nashata Pack is seen most frequently in this video. The pack has a distinctive breeding female who is seen bedding down in front of the camera toward the end of the video. She can also be seen “slipping” on the ice in another clip.

The Voyageurs Wolf Project, focused on understanding the summer ecology of wolves in the park, notes that there was a “very cold stretch last fall for several weeks in October during which all the ponds and lake edges froze,” so “some of the ‘wintry’ scenes in the video are actually from October and November.”

Kabetogama Peninsula is about 115 miles northwest of Duluth.

The interesting part is that with the exception of the wolves and the bobcat we got the exact same images from a beaver dam in downtown Martinez. But you knew that, didn’t you?


In all the world there is only one woman I admire so much I’d hand her the keys to the website in a heartbeat and let her take over Worth A Dam tomorrow if she were that foolish. She is without question, the kindest, bravest, beaver-lovingest woman on the entire planet, and that’s saying something. Thank goodness there are more than a handful of us now.

I’m speaking, of course, about naturalist, illustrator and author Patti Smith.

Patti Smith: The View from Heifer Hill | Wild times

While I have been enjoying the slowdown in human activity — fewer cars on the road, fewer planes in the sky — things in my backyard have been anything but quiet. On the last Saturday in April, I hiked up to visit Henry and Gentian, the former mate and the two-year-old offspring of the venerable Willow. The two beavers had survived the winter and had evaded the bear that killed Willow. When I arrived that evening, however, I found the two apples I had left on my last visit. I saw no sign of recent activity. Henry and Gentian were gone. Perhaps a matchmaker had whispered in Henry’s ear? Willow’s daughter Dew lived downstream and was also single.

Not since Lily pond have a cried as much as I did when the bear ended Willow’s journey.  It is certainly sadder to watch beaver death thru the eyes of a human than it is to observe through the eyes of a beaver. They are much more practical and unsentimental than we are. I learned that from our beaver mom’s death and the way her family stopped even acknowledging her when she was ill.

Dew was last featured in this column in January when I discovered new pond construction in the brook just below my house. Starting a new pond from scratch in winter is an act of desperation. In winter, beavers are supposed to be cozy in a mud-plastered lodge with a well-stocked larder. I would have been more worried if an ordinary beaver had undertaken such an endeavor. However, Dew had created this pond — Dew, the daughter of Willow, and a veteran of eight winters.

It was dark by the time I reached Dew’s pond that night. She swam over and climbed ashore, making the long, low, huffing sounds that indicate agitation or warning. I left her an apple and headed down to the dam,

The dam had been worked on over the preceding week. I scanned the surface of the pond for beavers and saw the small beaver hiding in some alders. My headlamp beam picked up something else in the woods beyond — the reflected shine of widely-spaced eyes — a bear.

OH NO! Not another bear! Never mind what the literature says, bears don’t read scientific journals. And beavers are tasty. We just know they are.

Once upon a time, I believed that bears were not much of a threat to adult beavers. Indeed, according to the literature, bear predation on adult beavers is quite unusual. Black bear diets are made up almost entirely of plants, with insects for dessert. Still, the footprints in the snow last December left little doubt about the fate of Willow. Furthermore, when I rediscovered Dew’s son Charley living upstream this spring, he had some scars that seemed most likely the result of bear claws. Given this evidence, I suspected this bear was after more than the sedges sprouting along the pond shore. I yelled and clapped to scare it away, but from the far shore, I was deemed non-threatening

I returned to Dew’s pond the next morning. The bear had bashed in the roof of Dew’s lodge and clawed away some of the mud and sticks. Still, the sturdy latticework of larger branches prevented access to the living chamber.

When I returned that evening, I discovered the more significant havoc. When Dew came ashore for an apple, I could see a deep slash across her wrist and a couple of smaller scratches on her face. Wounds oozed through the dense fur on her shoulders.

Ouch. Ouch. That lousy bear. I mean I like them in theory but don’t attack beavers, okay? Is it going to have to go to to rehab? That’s such a disruption in a beavers live.

As I write this column, I am sitting on the shore of the pond in the warm sunshine four days later. For the last few days, I have spent a lot of time here persuading Dew to eat antibiotic-laced apples. Today, a kingfisher wings overhead. Chickadees sing in the alders. The little beaver has climbed the opposite bank and is eating some spruce twigs. When Dew finally deigns to rise from her diurnal slumbers, she swims over and limps ashore on three legs. A ribbon of dead tissue dangles from her shoulder, and her front paw has doubled in size. Still, she is using it more than she was yesterday. She eats her apple then sits up to scratch her belly. The little beaver dips into the pond, swims over, and climbs up behind Dew, providing my first close look at this elusive fellow. This cutie must be a yearling that Dew has had stashed away here all winter.

Antibiotic-laced apples!!! How many times did I dream of finding some non invasive way of treating our beavers! I wanted to dose the top layer of water outside the lodge with a tincture of conjunctivitis eyedrops when the kits were young. I dreamed of that when they popped their heads up it would fix their poor infection. Alas no one would attempt it. Patti works at a wildlife center and has been a respected soul enough that someone will let her try feeding antibiotic laced apples. Good for her.

I’ll be spending a lot of time at Dew’s pond over the next couple of weeks, making sure she takes her medicine. I hope like heck that it works. With so much of humanity fretting over the health of friends and families now, I know I’ll be in good company. I’ll bring my work and my binoculars. Beaver ponds are always busy with life, and most of it is peaceful. They are fascinating places to fret.

If Dew pulls through this, she is likely to be a wiser beaver and may have a better chance of avoiding this aberrant bear. Once I no longer need to worry about Dew, I’ll start looking for Henry and Gentian. I hope they’ve found a place of abundance and security for their next home. I expect I’ll spend some time sitting on their shores. May we all have less to fret about then.

I don’t care who knows it. I LOVE PATTI SMITH. I LOVE THAT SHE”S FEEDING ANTIBIOTIC APPLES TO  DEW! You should love her too. If you haven’t read ‘The beavers of Popples pond yet” order it right now and give yourself a treat. And lets all keep our fingers crossed or a swift recovery.

 


Call me crazy, but if it were up to me to write a book about bear cubs in a beaver pond I’d promote it with some really great footage:

Or some supporting research:

Or hey even an awesome illustration like this one by Ashely Wolff:

But what do I know, really. Because you could just as easily go on PRI and give an interview and maybe that would be all it took.

Earl J. Roberts’ new book “Bears in the Beaver’s Pond” is an inspiring fable of a beaver’s life with two bear cubs

Earl J. Roberts, a dedicated writer, artist, and retired teacher from Grass Lake, Michigan, has completed his new book “Bears in the Beaver’s Pond”: an evoking and insightful tale of an old beaver and his fostering of two bear cubs and innocently impacting the world he lives in.

Author Roberts shows how two dissimilar creatures can coexist in grace and cordiality: “When Old Beaver found it convenient to render aid to two hungry cubs, he never dreamed that he was creating a system in Asu Valley which spelled destruction to a unique society. This tale of some remarkable animals speaks clearly to our time.”

Published by Page Publishing, Earl J. Roberts’ enthralling masterpiece is made for children and adults, for it teaches all on how to be open to change and accept responsibility for things that are within their capabilities.

Inspiring fable? Like Jonathan living beaver? Well okay. Beavers are plenty inspiring, I’ll grant you that. And bears cubs are adorable. It’s true. But an allegory where they destroy society? Okay, Whatever. I guess it wouldn’t be a fable if you told the truth about how we’re the only ones destroying everything.

Although hey, I kind of like the idea of a fable where beavers are worried because some humans moved into their land and built a home and started a farm, so they talk it over with the wise old beaver because they are worried it will ruin the pond and afterwards they decide to dynamite it!

 


Ben Goldfarb wrote last night that he had just met the author of a cool paper on the thermoregulation of bears. Apparently the animals have a lot of stored fat just in case food gets scarce and as the climate heats up they need to cool off regularly in ponds. And guess what just happens to make some of the awesome ponds they use?

American black bear thermoregulation at natural and artificial water sources

He sent along a great national geographic video of the pond soak phenomenon. But as it happens I already had footage of a black bear bathing in a beaver pond that was sent to me a few years ago by the VP of the Sierra Foothills Audubon. This  bear is enjoying the beaver pond by his house.

Willie Hall of SFAS filmed this bear taking a dip in the beaver pond hear his house in Grass Valley. Apparently he’s enjoying a fish dinner with his swim. Because Beavers Benefit Bears.

 

Ben was thrilled to see it and is sharing it with the author because he thinks he’d love to see it.

Of course beavers help bears. Why wouldn’t they?
