After the warm days of October and November, now we are seeing a bit of cold with a first freeze (barely, in some places) yesterday morning. And it is December now; in the “meteorological” way of tracking seasons, winter starts on December 1st. Most of us use the winter solstice, December 21st this year, as the boundary between autumn and winter, but North Texas is at least hearing a few rumors of the winter to come. And that calls for a walk somewhere, putting our ear to the ground to listen.

I walked at Sheri Capehart Nature Preserve, eastward along the “yellow” trail near the big pond and then turned and walked up through a tangle of woods to the “blue loop” and back toward the boulders. It was 63 degrees, a jacket needed only when the breeze blew. The place was full of sun and damp sand, native grasses going dormant and a coolness that balanced the sun perfectly.
In my journal I wrote “Phenology Note” on a sketched calendar page, and made a few notes about the trees and leaves. “The trees are still mostly leafed out and green. Many oak leaves are tinged with caramel …. Some trees look ragged but we’re still waiting for autumn color and/or leaf drop.” Back near the parking lot, many of the cedar elm trees are becoming bare, but the oaks seemed barely touched by autumn.
Phenology is the study of seasonal events in nature, and so looking back through a nature journal can show how the seasons change from year to year in a place. What’s the average time when trees lose their leaves, and how much is climate change pushing such events to new places on the calendar?

Using a journal in that way puts me in the mode of science and data, my thoughts separated from emotions about climate change as if severed by a scalpel. But journaling can – and I think should – be more than intellectualizing. On a good day I’ll make room in those pages for what I miss from a time when life was anchored by things you could count on. Winters could be hard or they could be mild; summers might vary in how hot or dry they got; but after whatever variation in the weather, we always returned to an arithmetic mean, an average that we all recognized as something we could count on. But now the math isn’t our friend, and the arithmetic mean is shifting upward and we don’t know what we can count on.
I kept walking, looking and listening for wildlife. A one-minute sample using the Merlin app detected no sounds of birds. I did find a delightful grasshopper resting on a leaf turned nicely red. Uploading a photo to the nature app iNaturalist, the insect was identified as a “mischievous bird grasshopper.”

Now this was a find – what kind of mischief does this sort of grasshopper get into? This particular one was sitting motionless, perhaps too cool for tomfoolery and just feeling lucky to have survived yesterday’s freeze. Adult grasshoppers often don’t survive winter except as eggs deposited in some protected spot, although with increasingly mild winters, more adults like this one might get lucky.


I wanted to follow up on the walk with Logan a few days ago in which we saw southern jack o’ lantern mushrooms. In that particular spot we visited, mushrooms were still there. It might be some particular combination of the right soil, shade, and moisture, but that place stood out with all those mushrooms. There was even a new one of a different sort. According to iNaturalist, it was a type of puffball mushroom. I want to go back to see if it matures to rupture and release a tiny cloud of spores.
Even without a lot of fall color, there were places where the bright, slanting December sunlight backlit a group of leaves and created a dramatic display of color. Going slow, we can notice so many small and wonderful things.

And that includes the mosses. After the way Logan brightened with every new patch of moss he found, I was attuned to them today and really appreciated how they grow on the sandstone up at the bluff. Looking at some boulders was like seeing a miniature topography of meadows and hills.

I also noticed, on the way down the hillside, that the bee tree is active again (there were no bees visible on that cool and cloudy November 29th). I stood for a moment, imagining the extent of the hollow space within that tree, and all the honeycomb built within the spaces, and all that honey!
