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

Tag: push-match


The phrase “Busman’s Holiday” is an English saying referring to a vacation during which you engage in activities very like what you do for a living. Reading Lily Pond is somewhat like that for me, since pretty much every dramatic thing that happens in the book has happened for our beavers. For example, when vandals “destroy” the dam and the pond collapses, I remembered several similar actions to our colony’s real estate. Of course it was never vandals: (at least not by strict definition standards). It was always someone with a paycheck from the city, and it was always done on purpose, even if it was denied later.

The worst and most obvious was the night Skip Lisle took the dam down by three feet to install the flow device. That stressed our colony horribly. It was heartbreaking to remember how all 6 beavers worked all night, ripping up tules and mud and pulling sticks off their own lodge, to make repairs. The following day one of our kits nearly collapsed with exhaustion and had to go to the lindsay museum where he later died. The necropsy found lesions from roundworm parasite, that had even made him blind, but I’m sure the panicked night(s) of hard work didn’t help.

A lot of the author’s “discoveries” are common knowledge to us. Maybe because we were such novices to begin with, we didn’t have years of “PROVEN THEORY” to combat. We just watched and learned. Beavers make use of varietal feeding. Check. Beavers work on dams from both up and down stream. Check. Beaver kits are taken care of by the whole family. Check. Beavers solve arguments and assert their power though “wrestling” in the water which doesn’t result in bloodshed. Check. Muskrats live in and around beaver lodges. Check.Beavers vocalize while feeding, but also to socialize. Check. Beavers repair holes and leaks under the water, not just at the top. Check. Beavers are adaptive in their thinking and problem solving. Check.

One thing I love about the book, is reading about things we observe all the time, but never had a “name” for. Hope Ryden describes the beavers water wrestle as a “Push Match”, which is exactly what it looks like. She says of it

I have watched these matches many tmes and thought a lot about them. Any species that posses sharp teeth with which to obtain food must avoid using those hazardous tools against its kind, for doing so could bring about its extinction. Moreover, it is certainly not in the interest of an animal to kill a close relative whose hereditary make up (being similar to his own) offers a backup means by which his own genetic material may be propagated. Finally, only a colony that is able to live in peace is assured the help of many hands and jaws in the creation and maintenance of its waterworks. This it is not surprising that the beaver has evolved strong inhibitions against biting, together with a ritualistic means by which to safely settle disputes.

Martinez Beaver Push-Match:

In some ways, reading Hope Ryden’s book is like finding a loveletter written by your grandmother. It’s wonderful to know what went on in her head, and to see the parallel’s in how she was feeling and thinking. But its also confusing to realize that someone else had these feelings, allowed their life to be shaped by them, and ultimately moved past them. It’s like seeing a familiar production from back stage. You know the plot and how it ends, but its delightful to see how the cast puts it all together.
