Beaver Visit

Nice job on the challenge question from yesterday. We haven't seen some of the mammals because of hibernation, but more so because they want to hide from predators and humans. Or if they are a predator, they will lie in wait for their prey - which are not humans. Also many of the mammals are nocturnal and will only come out at night - such as the beavers and porcupines.

So last night we went to go beaver watching and we really got a show!! We got there right at dusk when they start to become active. We had to be very quiet and sit very still to watch them. Beavers use their large tails to warn each other of danger and will slap it on the water when danger is near - it sounds like a gunshot.

Within about 5 minutes we could see something swimming in the water. It wasn't a beaver, but a muskrat - which are about half the size of beavers. Soon though, we did see one swim over to a near-by island and start gnawing on a branch. You can tell the beaver from the muskrat because a beaver has a v-shaped wave and a muskrat has a zig-zag wave in the water. You can see him in the picture right above. If you look really closely, you can see another beaver swimming behind him. We continued to watch and then he started swimming right in front of us!! He swam back and forth - like he was swimming laps. We were told that he was keeping watch on us.

Challenge: How do beavers go in and out of their lodges? Where is the entrance of the lodge located and why?

they have a hole inside of the lodges & why, because they swim in and out.

They have to get into the lodge from under water. This way predators can't get to them and the kits (babies) stay dry, warm and out of harm's way!
