Have I mentioned that T1 is obsessed with beavers? We're learning all we can about them. A few days ago I posted mysteriously boring video on some phenomenon we saw happening directly behind the beaver dam we're watching. Since then we've learned a few things.
  • Beavers don't actually live in the dams
  • Beavers live in lodges
  • Beavers often share their lodge with muskrats
  • Beaver actually do eat wood (the tender inner wood)
  • Baby beavers are called Kits
  • Even the kits practice dam building by trying to dam up little rivulets of water with leaves and mud
  • Beavers dam making is a community project
  • Beavers make dams so they will have more area to hide and it makes it easier to acquire food
  • The largest dam was 2,140 feet long, 14 feet high, and 23 feet thick at the base
  • Dams are very beneficial. They often create Wetlands.
  • Beavers slap their tails to make a loud sound and vibration to warn other beavers of danger
  • otters often bore through the dams to allow fish to flow through to shallower water, making it easier to fish.

Here is a really good diagram on how the whole beaver dam/lodge/community thing works! Click on it if you need a better view.

cool pic... I didn't know all that stuff. Isn't it fun to learn with the kids? :)

They have orange teeth.

Cool facts. Newborn rabbits are called kits too. I've always wondered how the different names came about for the animals. There seems to be no logic to it!
