Fifty years ago, any suggestion that an animal was more than a stimulus-response machine would be met with accusations of anthropomorphism — ascribing to animals some attribute that could only belong to humans. Pavlov rang his bell each time he fed the dogs and eventually, the dogs so associated the bell with the food that… Read more »
On television, we watch a show about lions. We watch a lioness raise her cubs. They are cute. But the narrator says in his slightly hushed narrator voice, “If she doesn’t find food soon, she will be forced to abandon her cubs.” Then, we see footage of a lioness taking down a young antelope. We… Read more »
Yesterday evening, a cardinal stuck himself at the top of a tree down the street and blasted the end of the day. His song was sparse. One descending note over and over. I don’t know if he knows only this much song or if he chose to give an abbreviated performance. Either way, it was… Read more »
The processes of the natural world operate at all scales, from tiny to enormous. But however large or small, complex or simple, every living thing is pushed by two drives: stay alive and reproduce. Knowledge of the natural world is essentially the details of how each species manages these drives. The natural world in our… Read more »
I have a nemesis in the plant world. Dogfennel. This weed, in which apparently no one is interested, has blindsided me time and again. Dogfennel is the kind of weed you don’t even really notice. That’s a photo of it above and you can hardly find the outlines of the plant. The only reason I… Read more »
There are many lenses through which to view nature in general and our Park in particular. Recreation, tranquility, civic pride, aesthetic beauty. There’s a more prosaic lens as well. Nature, and our Park, can be seen as a collection of eaters and their food. Some organisms are always one or the other; some creatures can… Read more »
The black tipped white moth is active in the Park right now. I’ve seen this lovely moth only once before in the Park a few years ago and mistook it for a butterfly, which made for a challenging ID. iNaturalist AI wasn’t as robust back then, or I would have had the answer in a… Read more »
Between travel and an injured foot, it has been weeks since I’ve really spent time in the Park. The two hours I spent Monday felt like a great big hug. The prairie grasses are everywhere announcing themselves. Even pros (one of whom I’m not), can struggle to identify prairie grasses when they are not blooming…. Read more »
Two years ago, I saw something I had never seen before. It was during our regular walking tour, so a bunch of other people got to watch it with me, but the only photograph I managed to get was of the footprints left behind. What we saw was a wasp laboriously dragging an immobile caterpillar… Read more »
The Jane Gregory garden is a model for what can be accomplished if we make decisions with insects in mind. (I’m going to refer you to my insect rant if you don’t understand why that is crucial to our survival.) The plantings are so lovely that it is one of the prime spots in Houston… Read more »
