Who's Out and About on the Day After the January 2011 Blizzard
Scott Dayton and I (Jamie) were out on the property checking waterfowl nest-boxes in the 18+ inches of snow. Snowshoeing was the only way to travel in these conditions. Although snowshoeing is fun, it can be really hard work when you are the first to break the trail through deep powdery snow. It reminded me how difficult it would be for some of our larger mammals to travel through the same conditions. Some animals have adaptations that are adapted for these conditions such as the large feet of cottontail rabbits and snowshoe hares so that they can travel on top of the snow. Moose is the only large mammal that inhabits northern CT that can walk through deep snow with their long legs. Bobcats, coyotes, fisher, and white-tailed deer, on the other hand, are hindered by these conditions. I expect to see more of their tracks and trails as soon as the snow compacts, but so far we found no evidence that they were moving around much today. These mammals rely on other adaptations to survive when they can not move very far to find food. They carry a layer of fat on their bodies that insulates and provides energy that maintains bodily functions. These adaptations are good for short periods of time and each of them use many other behavioral and physiological adaptations to survive the winters especially during these dramatic environmental conditions. Some move into the sunlight to warm their bodies, others reduce their metabolism so that they don't need to find as much food when it is difficult to find, and others sleep through the extreme winter climate. The only mammal sign that we observed today were weasel tracks in various marshes. The weasels bounded between shrub stands and dove under the snow to probably elude predation and to gain access to the subnivian (below snow) layer where all of the small mammals (mice, voles, shrews, moles, etc.) inhabit.

Coyote and Bobcat Encounter at Cat Swamp
~30 degrees F, 0% cloud cover, wind NE 0-5 mph, 0.5 - 1 inch of snow
Elena Sasso accompanied me to look for tracks on the Cat Swamp boardwalk and along the western side of swamp. We observed the following species' tracks:
bobcat
coyote (at least 2 individuals)
weasel species
red squirrel
grey squirrel
cottontail rabbit species
white-tailed deer
Along the trail on the western side of Cat Swamp we observed an interesting scene.
We observed a older scat with some fresh urine marks (foreground of the above image), with long paw marks that lead to the scat, and coyote tracks walking away from the scat, but originating at the far end of the paw marks. I suspect that a coyote encountered this scat in the trail, stopped urinated to leave it's scent, then pawed at the ground by kicking leafs and duff with it hind legs. After it left its calling card, it then walked away.
Another interesting encounter occurred when we were at the southern end of Cat Swamp. We were walking around the edge of the water looking at bobcat tracks and fresh beaver gnawing on Red Maple trees. We were about to start walking back to the truck when we observed in the distance a bobcat sauntering off into the dense undergrowth.
