Why don't i see beavers behind my house?
i found a couple of beaver dams on my creek.
The are in the dams? Or went to a Beiber reunion just kidding
Because Justin Bieber took their place.
Maybe they are hiding or spying on you. Sneaking around the front.
Beaver dens have the entrances under water. It's possible your beavers try to keep a low profile for safety and stay under water more than usual.
Beavers spend the winter in their lodge, huddling together. They eat food they have stored under the water, so they may not come out at all.
Dam I forgot the answer.
If it is a small creek, it is probably not a beaver dam, but a muskrat lodge. They are smaller than beavers and, as such, harder to see.http://www.fcps.edu/islandcreekes/ecology/muskrat.htm
they are nocturnal
Well, one, like nearly every other animal on Earth, beavers are INCREDIBLY afraid of humans, plus there is the fact that they are nocturnal, they still will keep as close to their dams as possible and as far away from your house as they can.
