These are old blogs imported from 360 to Multiply and then to Blogger. They were never published so I've been going through them and putting them into bogs that somewhat characterize them. These are from my blog cradle, if you will, written when I was a complete newby.

The mighty beaver (no perversion here)
Being challenged to use an animal for my avatar, I considered many things. Then I remembered a personality test I took in a workshop while in the public school system. I was a beaver, industrious, compulsive, creative. Okay, then. Well when I went looking for a beaver picture for my avatar, I ran into some info, so I'm including it just so you'll know.
Beavers are more than intriguing animals with flat tails and lustrous fur. American Indians called the beaver the "sacred center" of the land because this species creates rich habitats for other mammals, fish, turtles, frogs, birds and ducks. Since beavers prefer to dam streams in shallow valleys, much of the flooded area becomes wetlands. Such wetlands are cradles of life with biodiversity that can rival tropical rain forests. Almost half of endangered and threatened species in North America rely upon wetlands.
Besides being a keystone species, beavers reliably and economically maintain wetlands that can sponge up floodwaters (the several dams built by each colony also slows the flow of floodwaters), prevent erosion, raise the water table and act as the "earth's kidneys" to purify water. The latter occurs because several feet of silt collect upstream of older beaver dams, and toxics, such as pesticides, are broken down in the wetlands that beavers create. Thus, water downstream of dams is cleaner and requires less treatment.
Beavers' ability to change the landscape is second only to humans. But that is just one reason why we find the flat-tailed species fascinating. Adults may weigh over 40 pounds, and beavers mate for life during their third year. Both parents care for the kits (usually one to four) that are born in the spring. The young normally stay with their parents for two years, and yearlings act as babysitters for the new litter. While some beaver behavior is instinctive, they also learn by imitation and from experience. Dr. Donald Griffin, the father of animal cognition, has said, "When we think of the kinds of animal behavior that suggest conscious thinking, the beaver comes naturally to mind."
Wildlife rehabilitators find beavers to be gentle, reasoning beings who enjoy playing practical jokes. An Indian word for "beaver-like" also means "affable." Once weaned, their favorite foods include water lily tubers, clover, apples and the leaves and green bark (cambium) from aspen and other fast-growing trees.
