It’s traditional to be thankful around this time of year in the United States, but that isn’t easy this year. Science and the environment are under serious attack, and it’s not clear that the situation will improve anytime soon. We are losing time we won’t get back: students who might have been our next scientific leaders won’t be able to afford education and will turn their careers elsewhere; species and habitats will be irretrievably lost.
It’s too easy to get buried in these discouragements, exhausted and dispirited, and turn away rather than watch more damage done. But we can’t let the things we love become things we don’t want to think about. The things we love are in peril: if we are to save them, we need to think about the love as well as the peril.
Let’s be thankful for the things we might lose. Let’s remember why we treasure them.
I am thankful for all the other lives in this world: all the alien minds, the perspectives built of senses I barely have (smell) or lack entirely (echolocation; detection of magnetic fields), the goals both remote (time to fly from Alaska to New Zealand!) and familiar (must protect my family!), the pleasures that are at once recognizable and strange (the contentment of a mother oppossum with all her babies in her pouch; the joy of a dust-bathing sparrow). I am thankful for how these other lives expand my mind and also for how they have nothing to do with me. I am thankful for the opportunity to glimpse some of them.
One of those other lives: a one-legged (but healthy) Black Phoebe.
Science requires careful planning, foresight, and scrupulous attention to detail. Everything must be controlled so that the variables of interest can be examined. One mistake could bring everything down. Only with years of training can someone hope to add to our body of knowledge.
But if you take all of that too seriously, you’ll spend all of your time planning and theorizing rather than looking—and the most important part of science happens when people just start looking.
Peder V. Thellesen is a dairy farmer in Denmark. He has no formal scientific training. Evidently he loves starlings: he started banding them and observing their nests in 1971 and continued to do so every year, in nestboxes on his own farm and on his neighbors’ farms.

It’s the time of year when migrants come through the banding station on their way from their breeding grounds in the north to their wintering grounds in the south. We see a greater variety of species now—not just those who like to breed here, but everyone who thinks our patch of forest looks like a good place to stop for a snack. It isn’t just that these are different species, though: these birds have a different feel to them. These are travelers on a genuinely long and perilous journey. We banders are, I hope, just a blip in any bird’s day—a frightening moment to be shaken off by mid-afternoon—but the days we interrupt for these migrating birds are epic days.
This is physically manifested, on the birds, as fat.
I feel almost disloyal, saying it, but here goes: I’m working on a new project. A non-junco project.
Not that I’ve stopped working on juncos. When we teach science, we tell students “Science is never finished”—true in the larger sense that science is always testing new hypotheses, refining old theories, and correcting erroneous ideas; but also true in the sense that we scientists pretty much never stop doing things once we start them. I’m still analyzing data on the juncos.
But I’m now also generating data on tuco-tucos.
The noble tuco-tuco, a subterranean South American rodent.
You would think an embryo in an egg could relax. They can’t eat, or go anywhere; what can the world ask of them, besides that they grow? A decade ago it would have seemed ridiculous to talk about “embryo behavior.” Now, though, we know that even embryos have things to do.

It’s almost a pity that we introduce children to caterpillars so young. The magic of the transformation of a squishy, unimpressive tube into a living, fluttering creature apparently made of stained glass gets muddled up with the rest of the magic of childhood and is too easy to forget when we grow up. Everyone knows about caterpillars turning into butterflies, but almost no one really thinks about it.

Even before they turning into butterflies (or moths), caterpillars are impressive. They hatch tiny, into a bird-eat-caterpillar world, and their one crucial job is to grow big in time to metamorphose. This isn’t a particularly complex task—there’s a reason caterpillars are basically just digestive systems on legs—but it isn’t necessarily easy, either. They need to find the right food and eat it quickly without being eaten themselves.
