The change in my cat’s fur reminds me of a larger-scale transition undergone by the snowshoe hare. This hare sheds her brown summer coat at the end of autumn while growing new fur that is not only thicker, but another color altogether to help stay aligned with the change in seasons.

An international team of researchers at the Academy of Sciences of the Czech Republic found a species of termite that takes the act of self-sacrifice to the extreme.

A flutter of striking black, white, and grey outside the window caught my attention, and as I walked closer I saw a dozen large-bodied, sharp-beaked birds hopping around on the treed hillside. The Clark’s Nutcrackers are here again!

I am always surprised to see moss exposed in wintertime. Hiking on trails or backcountry roads, I encounter moss-covered rocks, or mossy ledges that crop out on the slope, like a bed where the quilt has been pulled back part way and you can see the sheets peeking out underneath.

When the queen-to-be hatches, worker bees will feed her a strict diet of rich royal jelly. After another five and a half days the larva changes into a pupa, and seven days later the new queen's cell is sealed shut to hide her from my prying eyes.

Recently, I have been thinking about the food chain that sustains the wildlife here. Where does it begin? When did it begin? What if I looked more deeply than what I can see with my eye? I want to learn about the microbiome of this wonderful area.

Sage is suddenly everywhere—everywhere, that is, where it’s not too parched even for this hardiest of dryland flora. Low, vertical cliffs of tan sandstone have replaced the steep, evergreen-covered mountains as the dominant landform. We have just entered another world: the Bighorn Basin.
