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

Category: New Species


A while back I stumbled onto a delightful read about the work of beavers on an attractive website called Tamia Outside. It encourages no-octane exploration of the outdoors through cycling or paddling, and had some lovely things to say about watching wildlife. Tamia and I connected around a series of intriguing photos taken by a contact of hers who thought they might be beavers at the beach. (!) This prompted her to work on an article about telling beavers and muskrat apart, and to ask permission to use my movie about the task.

Yesterday her efforts were displayed with outstanding results. I thought I’d encourage you all to go over and check out her success, which has things for all of us to learn from.  She even has rare photos of beaver scat, which it took me three years to find online. She says lovely things about our website and we had 15 visitors from her site yesterday, so pay back the favor and click on the link right away! Pause while you’re there to rewatch the movie because it’s actually one of my favorites. It was my third effort ever and used windows movie maker no less (that kept shutting down and dumping things every five minutes)! I actually think the beaver whose tail slap you see in that footage was an early yearling. I don’t recognize the size or head now and I was told by someone that they saw three beavers on the bank in early 2007. I think this beaver was our very first “disperser”

Nice work Tamia, we appreciate your research and the resource. You might add this fun clip for a up close demonstration of size difference!

Mom and kit seen last night and our third arrival merited a “tweet” at the Contra Costa Times.

“That they could get it clear?”
“I doubt it,” said the Carpenter,
And shed a bitter tear.

“I hate to say it, but I’m surprised something like this hasn’t already happened.” This, tragically, was the death by suicide of a charter boat captain hired by BP to take part in oil leak cleanup or protection efforts in the gulf.

The quote comes from Jason Bell, who worked for William Allen “Rookie” Kruse, 55, for three years as a deckhand and pilot. Kruse put a bullet [1] through his head this morning at a marina in Fort Morgan, Alabama. His boat was about to launch today and he was reportedly upset with the oil leak, the cleanup efforts and loss of income, and wondering how he would be paid for taking part in the Vessel of Opportunity program.

The newspaper related that Baldwin County Coroner Stan Vinson “said witnesses told investigators that Kruse had been upset about the loss of business caused by the closing of fishing grounds and public perceptions of the Deepwater Horizon oil spill.” Perhaps ominiously, Bell said, “He wasn’t any more aggravated with the whole situation than any of the rest of us.


Early morning visitors to the dam this week have been treated to a spectacular display of winged mammals over and under bridges, over and under trees and swooping back to bed under the clay tiles they call home. These are Mexican freetailed bats, such fast flyers that they are considered the “jets of the bat world”. They prefer to roost in caves but will settle for attics and abandon buildings. They like to be close to water because it draws the insects they eat and also allows them to drink.

A single bat baby is born each summer and must roost on its own. It’s mother must find it to feed, identifying its call out of hundreds or thousands. Before you reach for that phone to call the exterminator you should know that a single colony can consume as much as 250 pounds of insect a night. Every individual can eat 600 mosquitoes a night. Now that’s what I call a bug zapper.

If you head down to the beaver dams after dinner, before they’re out, and you are blessed with sharp ears you can hear them chittering as they get ready to wake up for a night of feeding. These bats migrate every winter to mate, and are among the most widespread mammal we have. However populations are sharply declining, and this is thought to be do to all the insecticides sprayed on their nightly meals.

Our bats are not declining. While you’re looking down in the water for beavers don’t forget to look up for bats. They’re quite a sight.

I have decided to give up trying not to post about the oil in the gulf. It’s on my mind. I want it to be on everyone’s mind. Last night on PBS Newshour BP Managing Director Robert Dudley said that they had deliberately underreported the amount of oil originally so as not to alarm people. The mind reels. The jaw drops.  I’ll just post a daily piece of news about the effects or the arrogance or the heroism or the cowardice or the ramifications under my beaver-beat and I promise when they plug the leak I’ll stop.


The ‘hounds of gabriel’ is an ancient phrase referring to the bay and flap of migrating geese overhead – their heavenly location suggesting they belong to the Archangel Gabriel. The older term is ‘ratchets’, (ratchet being a hound that hunts by scent.) I mention it because today was a ‘fowl’ morning for beaver watching. A creek sans castor, but crowded with paired up ducks making their survey of the best nesting areas. From the right came the honks of thirty geese in V’d flight and to the left, from the hills, came an unmistakable ‘gobble’. It’s the first time I have heard turkeys from the dam site, but at one point they were close enough to echo off the county building. What I wouldn’t give for that picture!

I am told that the wood duck boxes have been inspected and that two have ‘bowls’ which are initial pre-nests that indicate a prospective buyer is thinking about closing escrow. All in all we should have a population explosion of baby ducks this year. I can’t wait.


Tyto Alba came to my house last night…

When I got home from work at 8:30 there was a familiar “click click click” sound coming from overhead. I recognized it as being a barn own echolocating and glanced up. Barn owls have asymmetrical ear placement and can locate their dinner entirely without the use of sight. They are enormously widespread across the globe, and its thought that they eat more rodents in a single night than any other animal!

Nothing to see at first. I took my briefcase out of the car, still looking up. ‘click click click!’ The sound came closer, closer. And then a burst of white like a flapping cloud as the barn owl flew over my home and yard. Beautiful to see. We used to have owls every night until the habitat in the video above was senselessly destroyed by tree shaving. Sigh. I’m always happy when we get a sighting now.

Click Click Click. He circled back, coming closer. Then a heron-sounding squawk, or maybe a screech, sounded from the bushes right where I was standing. The clicking came closer, and the screech rose in a white plume of feathers and became another barn owl! Taking flight right from my bushes! And they clicked and screeched to each other, gaining altitude, sky dancing in the darkness above me. It was breath taking!

Let’s hope the clicking and circling was the fella saying “I have a great place to nest, baby, follow me!” And the rising screech was his intended saying, “I guess you’re kinda cute.” And they’re going to raise lovely feathered babies right near my house (or your house) soon!

 


PGE may have falcons, but Mirant has hummingbirds! These two babies are being raised in a nest on a bearing cooling water return line for 6 unit condensate booster pump. The water line is warmer (but not too warm) so it’s an ideal nesting location. Mirant employes have marked off the area and are keeping an eye on their young visitors which are approximately ten days old. These photos were taken March 21st by Jon Ridler, 24-year employee at the plant and member of Worth A Dam.
