Week 46

Mice will move indoors after a heavy snow. Considering their size, they make a lot of noise / Until snow covers them, blueberry bushes will be browsed by deer / The glossy, toothed leaves of pipsissewa, or prince’s pine, stay green all winter. Its botanical name, Chimaphila, is from the Greek and means “to love winter”.

Week 45

At over 100 pounds, this year’s male bear cubs have well outgrown the females / The brown, fertile fronds of sensitive fern will release spores in spring. Gray fronds are two years old, and their spores are already gone / Chipping sparrows have big appetites: each one will eat 160 times its weight in seeds over the course of a winter / Bullfrogs and green frogs spend the winter in ponds, insulated against freezing by the layer of ice on top of the pond.

Week 44

Healthy bear cubs now weigh at least 75 pounds and will soon follow their mothers into winter dens / In cold weather, carpenter ants cluster together in the center of their nest and are helplessly sluggish / Luna moth cocoons, wrapped in leaves, have fallen to the ground / Twinflower fruits are eaten by ruffed grouse and other birds that feed on the ground / Autumn overturn is completed in lakes as the water temperature reaches a uniform 4°C (39.4°F).

Week 43

Frail, light tan Bruce spanworm moths, also called Hunter’s moths, may be abundant in sugar maple stands on sunny days from mid October through November / The white midribs of the leaves and the bright red berries of partridgeberry both contribute to the good cheer spread by this ground-hugging plant / Snow geese may still be passing through.
