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

First the silly thing….

Beaver cuts tree down, starts grass fire south of Saskatoon

Capture SASKATOON – A beaver caused a large grass fire Saturday, according to the Saskatoon Fire Department. The blaze was located near Valley Road, south of the city near The Berry Barn.  The fire department says the animal chew ed down a poplar tree which fell on a power line.

Those beaver arsonists are the worst! Smoking in bed, starting fires with their appetizer course, with zero regard for personal property. They obviously don’t know how hard it is to put up those power lines in the first place.

Now, let’s share in the wondrous developments at the Napa beaver pond, where Rusty has been patiently waiting for a glimpse of the new kits. Of course while he’s waiting there’s lots to see. Check out this weekends bounty.

He even got video of two otters at the sight having a little tussle. Megan of ROEP thinks it mighthave something to do with mating. How exciting!

Now for this truly stunning photograph brought to my attention by someone I can’t yet bring to your attention. Isn’t this BEAUTIFUL?

kit ride

This is the kind of photo that every wildlife watcher dreams of getting. That perfect moment when opportunity crosses your path and everything goes right. He writes that it’s a mother carrying her kit, which is a fair assumption. But we in Martinez know it might not be true. The most stunning footage I ever got was dad carrying both kits. And we only know that because of mom’s beautiful tail clue.

This is the kind of photo that saves beavers, so I hope Jeff doesn’t mind too much if I share. You can see Jeff’s remarkable work on flickr here.

And finally the best for last. Now pull up a chair and gather close because this is really important. First, a little background. In the films about Grey Owl they describe him doing a special call to bring the beavers. The way a duck call brings ducks. Which I would have ignored as silly if I hadn’t also read in a book about someone who hand-reared kits in Canada who said that their brother was a trapper and he taught her to call beavers. She noted that it was so powerful she would never teach anyone else because she didn’t want trappers to use it. So I was curious.

And then there’s Bernie Krause’s amazing recording of the beaver after the dam and his family was blown up. It sounds very much like he is mourning. But I after I heard it I always wondered if he was calling to find them. (Which is what we would do if our homes were blown up and we weren’t sure if our family members were inside.) I discussed this idea with him, but he was fairly disinterested. But then yesterday – out of NOWHERE – I stumbled on this.

I know that readers of this site mostly don’t click on the videos. Life is busy and who has time? Believe me when I say you want to see this. (I was so scared it would end badly I practically watched it with my eyes closed the first time. But nothing bad happens, trust me.) And this is really, really worth your time.

(I trust if you know any trappers, you won’t show it to them.) And honestly, don’t practice this call on our beavers because they’ve been through enough. But isn’t that amazing? Do you realize what this means? It means parents call kits. And beavers call each other. I am sure this is a youngish beaver, looking for his family. What surprised me was not only that it existed, but how very different the sound is from a kit whining. Almost like loud nasal mooing. Also I could hear the similarity in the young beaver answers, and hear how similar it is to our kits whining. It made me think that beaver kits are imitating adult speech – just like children!

Honestly, this is a big deal. Such a big deal that I got an email last night from Bernie Krause himself.


A man gets tied up to the ground
He gives the world its saddest sound
Its saddest sound

About 6 months ago I came across the soundscape  work of bioacoustician Bernie Krause on this Science Friday episode. It of course made me think about beavers and wonder whether anyone had ever tried to listen for vocalizations under water. I asked around and eventually connected with Dr. Krause through Richard Dale at the Sonoma Ecology Center. He thought it was an interesting question and said he had not heard much beaver recordings even above the water, except for tail slaps and this:

I do have a rare recording of a male beaver vocalising. A colleague of mine who has been recording at a remote lake in Minnesota for many years, was visiting his favorite springtime spot when a couple of state fish and wildlife agents hiked in and dropped a couple of sticks of dynamite into the beaver dam that was the centerpiece of an entire micro ecosystem, and the cornerstone that held the infrastructure of the lake intact, killing the female and the offspring and wounding the male. That evening, our friend managed to capture the male, swimming in circles, crying out for its mate. Saddest sound I’ve ever heard from any living being, human or otherwise.

Well the internet is an amazing thing. You can be listening to a famous researcher one day and exchange emails with them the next. And it can do this – mind you, if Bernie’s description wasn’t warning enough to the compassionate souls reading this website add mine to the list. His recording is not for the soft of heart.

All this to say that tonight Dr. Bernie Krause will be presenting his awesome soundscapes in Sonoma at the Valley of the Moon lecture series.
