Yesterday morning Mom beaver was seen chewing willow with another, mostly adult beaver that was not dad. We were thinking our three yearlings, not seen since March, had moved on to seek their fortunes. Apparently at least one of them is still around.
Yearlings “disperse” around their second year and head off looking for territory of their own. They will go anywhere from 2-30 miles away looking for a place to call home. Sometimes you hear the very strong belief that “beavers always go down stream from their parents”, but obviously if that were true by now all the beavers in the world would be in the ocean. In fact, several dissertations have been done on this subject, and it turns out that slightly more yearlings go upstream than downstream, but that the ones that go upstream are more likely to come back.
“Coming back” is an interesting thing beaver families allow. Although they wouldn’t let another beaver move into the territory, they will let yearlings come back and hang out with the colony for a while. Every family member recognizes them by their scent. Beavers are the only animal besides porcupines where the females “disperse” for greater distance than the males. This again speaks to how importantly the beaver family is a matriarchal society. It’s important to note that as unlikely as it seems, dispersal also happens over land. Beavers walk their way to freedom, and often when we are at displays or events the most prominent story we hear from strangers is that “once they saw a beaver hit by a car.” In fact, more people have probably seen a dead beaver than a live one, I guess because they stay still longer.
At any rate, one of our yearlings is in the lodge still, and whether this means he didn’t ever leave, or he’s come back to try again, we have a family of at least three, possibly more. Interestingly mom was seen swimming upstream last night, past Starbucks, past ward street and towards where the creek is under cement. Not sure what that’s about, but very interesting to ponder.

“Unprecedented”. “Nobody could have predicted”. “Never before”. These words keep getting used to describe the oil volcano that is busily digesting its plug at the moment. Here’s some very smart reporting showing you that this isn’t as unexpected or new as you might think.
