They mate at around three years of age. Females gestate the young for roughly three months before giving birth. A female will typically have one litter of kits a year, with litter size ranging from one to four kits. These kits, along with those born the previous year, stay with their parents inside the lodge. Beavers can stay underwater for 15 minutes without coming to the surface.
They have transparent eyelids that act as goggles so they can see as they swim. A groundbreaking bipartisan bill aims to address the looming wildlife crisis before it's too late, while creating sorely needed jobs.

Ask someone about the defining characteristics of a beaver and they'll probably mention one of three things: a giant tail, giant teeth or a big, brown body.

Beavers are constantly wearing down their teeth, so their teeth are constantly growing. Looking at a wetland in the Iowa Great Lakes, you might see ripples coming from a moving little dot. Muskrats are adorable creatures that can glide through the water because of their dense fur that traps air for insulation and buoyancy, and they are very active this time of year.
Although creatures in the weasel family are often just called weasels, they are actually split up into a variety of species.
You might be seeing an ermine, otherwise known as a stoat or short-tailed weasel, Mustela erminea , the least weasel Mustela nivalis or a mink Mustela vison.

These herbivores also eat leaves, woody stems and aquatic plants. Some of their favorite foods — poplar, aspen, willow, birch and maple — are also conveniently their primary building materials. Beavers also store branches on the muddy pond floor beneath their lodges to eat during the winter when they spend most of their time inside.
The cool water acts like a fridge, keeping the stems fresh and preserving their nutrients. Bonus: Beavers are very dexterous and tend to hold their food between their front paws to eat. There are two living species of beaver: the North American beaver and the Eurasian beaver.
North American beavers typically weigh between 35 and 65 pounds and are feet long standing
