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

Month: December 2010


Consider the River Otter (Lontra canadensis). Cheryl snapped this photo of the visiting fish-eater near Starbucks yesterday. Otters have huge territories so he/she has lots of different feeding spots to choose from but the Martinez Beaver Ponds are definitely on the  short list. Since beaver dams trap organic material that insects break down, they increase fish populations and become feeding grounds for lots of wildlife.  Remember that in the fall we saw mom and junior visiting the area so that she could show him where to find easy fishing once he was on his own. Observers say the otter was showing his/her talents with fearless aplomb yesterday, popping out of the water to savor each victory.

I dearly wish we’d see an otter family someday, with little pups. Otters start out life much more slowly than beavers, not learning to swim until they’re 8 weeks old! Pregnant females raise their pups entirely by themselves, with no help from Dad, who will fertilize anything he gets his paws on. Otters can’t dig their own den, so rely on other animals to do it for them (hint, hint). Once an otter is impregnated it can delay implantation of the fetus for up to 8 months, timing the birth for the spring.  But in the mean time we are always delighted by an otter vist. A special benefit of this photo is the glimpse of his curving, tapered fur tale.  If you’re still not sure you can tell them apart from beavers, this might help:

In solidarity for our frozen East-Coast friends today I thought the website should snow, too. Enjoy!

Cheryl went looking for our ‘fancy ducks’ this morning and sends this photo of last nights beaver-chew party. She says everyone enjoyed the otter putting on a show at Starbucks and up and down the creek, catching big fish each time he dove. Photos to follow!

Hooded Merganser at beaver dam: Justin Watts 12/23/10




Check out our new Christmas visitors to the dam site! It’s a male (left) and female (right) pair of hooded mergansers. These are obligate nestors who may have come to inspect the wood duck boxes Mitchel installed. If we’re lucky they just might stick around. A trio of young birds came on valentine’s two years ago I’m guessing they were emissaries checking the place out. Apparently they liked what they saw.

Here’s hoping we see these someday….


My Dad was at the dam at dawn but saw no beaver ripples. I guess the family is busy inside the lodge opening their presents.  Just in case you don’t recognize the tree below, its willow frozen up!


Last night while we kept watch for beavers at the secondary dam where they’ve been recently spotted, they sneaked to the primary dam and gave a much awaited show to a young couple who had driven all the way from Modesto just to see them. They reported an adult and a kit but we don’t know if they saw Dad or GQ.

Meanwhile we were treated to a silent movie of the luckiest green heron ever who caught a MONSTROUS fish that was easily a third of his body length. He sat with it trapped in his beak for a long while, afraid to move it into swallowing position for fear it would get away. Then he embarked on the impossible task of turning it around working it into his throat, shaking the banana sized wriggling thing into his stomach. We saw the fish become a tail and then nothing at all.

For a moment after that the bird looked down at the water as if he still ought to find more fish. Then he seemed to feel the moving weight inside him and think better of it. With a repose worthy of an antacid commercial (“I can’t believe I at the whollllle thing”) he sat very still in the dark for the rest of the evening.

Have an excellent day what ever you do and here’s a little tradition I’ve grown very fond of.
