The North American beaver prefer the (inner) bark of aspen and poplar, but will also take birch, maple, willow, alder, black cherry, red oak, beech, ash, hornbeam and occasionally pine and spruce. They will also eat cattails, water lilies and other aquatic vegetation, especially in the early spring. Beaver families consist of an adult male and adult female in a monogamous pair and their kits and yearlings. Beaver families can have as many as ten members in addition to the two adults. Groups this size or close to this size build more lodges to live in while smaller families usually need only one.
The biggest difference between beaver on the internet and the ones that live in our area of Illinois is their denning choices. Beaver here will use a bank den that can go unnoticed, until the family grows. They will also use a sewer pipe or culvert pipe as a den. The beaver lodge will evolve from a small bank den when the room is needed and look more like the ones on the internet. To identify a beaver from a muskrat isn't that hard, a beaver will swim in the water with only its head exposed, and a muskrat will swim with the head and body exposed using the tail as a ruder.
Trapping for beaver can be year round if ice is good, they do not hibernate and will stay active even under ice. In November bachelors or single males will den and build dams in some of the weirdest places. They only look to get through the winter until spring mating season. Normally around here young beaver will make their appearance around the end of may or June. Its at this time when activity to dam building and lodge building become evident. You will notice more tree damage and fresh tree limbs in the water.
