Oh beaver the family that lives here in this lake at the hoof of the Teton Mountains in Wyoming while beavers can get around perfectly well on property they’re most at home in the ocean where their webbed rear paw at large Pavelec tail construct them powerful swimmers above and below the surface like marmots beavers feed on all kinds of vegetation and devour timber as well as foliages and they’re accomplished engineer’s this great pond is absolutely at their own creation merely a few years ago this shoal pebble is stream flowed straight down the depression then their own families of beavers moved in and constructed a dam the primary torso of it is built of boulders on the downstream side it’s been ordered with logs some of them big-hearted and quite ponderous and on this side it’s been compressed with mud and vegetation it’s been built so accurately that it is to within a few inches horizontal across its entire section of about 150 grounds from one feature to the other and the reservoir it established unfolds upstream for almost a mile so important is their damn to them that if they detect the slightest opening generally by hearing the announce of seeping irrigate “theyre starting” repair work immediately mud is needed as well as records the mend crew will labor away until the spill is fully restored maintaining spray at a high level makes beavers various advantages one of which is that it deluges the surrounding woodland and so enables them to swim in safety to their main source of food they increase the distance they can swim by digging paths that lead into the very heart of the woodland now they can use their abrupt incisor teeth to strip off the bark from a failure tree trunk and nibble at it while still being close enough to water to slip away should a bear or a mountain lion turn up their network of paths likewise enables from Clefairy whole limbs back to their pond and there where the liquid is deepest they dive down and propagandize each diverge firmly into the mud at the bottom this is the beavers fridge where the greenery will obstruct fresh through the long winter when the pond is covered with ice stocking the fridge takes a lot of work and the beavers are at their busiest in autumn at one back of the lagoon Sam’s there Lodge a fortress constructed of limbs and boulders that’s so strong they’re not even a bear could break into it the only entrance is through tunnels that open underwater and the beavers take refuge here whenever they are alarmed that was a warning signal to say that danger was around let’s say me and now I may not understand the Beavers for some time they can stay underwater for five minutes at a time up to 15 if they need to they can actually get back to the safety of their Lodge without putting their intelligence above the surface for a single second most inns have at least two different admittances by October winter is well underway but whereas marmots would now be sleeping the Beavers are still active and will remain that way throughout the winter even when the pond ice is over entirely they’re still able to swim under the ice to get back and forth to their Lodge no one knew exactly what went on inside the lodge during winter so when the Beavers were away we lay got a couple of infrared cameras in order to find out a fork from the fridge is being brought back to the lodge for the whole family to feed on and another no wonder they don’t need to hibernate with this ingenious setup the cabin is warm and safe even in midwinter and the only sign of activity in the snug dwelling beneath the snow is hot air rising from the ventilate at the top inside our cameras catch a glimpse of what at first sight looks like a very small beaver it’s a muskrat they’re a pair of them in now this is a new observation to the Beavers actually no in the pitch blackness that there are strangers among other issues we noticed that the muskrats regularly left the lodge to forage under the unless and on several occasions they returned a few minutes later with a load of fresh reeds perhaps the muskrats are paying rent by regularly supplying fresh pillow for the lodge maybe that is why the Beavers accept them and even allow them to share their food ah infrared lights are no longer welcome it seems
