I knew there was a reason I kept all of my field gear…

And that reason is that I am a hoarder. But that turns out to be fortunate, because I’ve become involved in a project that just so happens to need someone to go sample some birds for them, and I already have all the tools.

In a few weeks a co-conspirator and I will head off to North Carolina and West Virginia to chase three target species:

Another delightfully anomalous junco

Readers who have been with me a while will remember “Buddy,” the white-spotted male junco who lived near my workplace for years. Unusually-colored juncos aren’t as rare as, say, the recently-spotted yellow cardinal, but they aren’t common either. (In my field work in the Sierras we banded ~500 juncos, and only one had a color abnormality.) As a lover of both rare birds and juncos, I get pretty excited about them when I find them.

This particular junco flashed up out of a bush as I was walking past. The size, tail, and movement pattern all said “junco”—but when the bird landed in a tree and I got a good look, my brain’s bird-ID function got confused: “Big chickadee!” it suggested. “Small kestrel! Big-small-chickadee-kestrel-junco!”

When forbidden love creates a new species

Choosing your mate is an important decision. If you are a species that cares for your offspring, you and your mate need to be able to coordinate your care, and you must be able to rely on your mate to pull their weight. (Watch the albatross cam to see how the mated albatrosses depend on each other—one stays back with the chick while the other flies off to get food. If the food-getter never came back, or the chick-minder wandered off, the chick would die.) More fundamentally, whether or not you care for your offspring, you and your mate must be able to have biologically healthy offspring together.

Animals do not always get this right. The recently-in-the-news stories of Thomas the goose, who bonded with a black swan and spent his days helping that swan and his mate raise their cygnets, and Nigel the gannet, who was devoted to a concrete gannet dummy, are good examples of the errors an animal heart can make. From an evolutionary perspective, these are bad decisions: they prevent the lovestruck individual from passing on their genes to future generations. (All reports suggest that Thomas and Nigel appeared happy, so from an individual perspective, the mistake may not be so bad.)

But sometimes—very, very rarely—an error in mate choice, instead of being an evolutionary dead end, is the beginning of an entirely new lineage.

Banding station highlights are small and fuzzy

The sun rising behind the mist nets at the banding station.

‘Tis the season for year-end “Best of” lists, so I thought I’d do something of the sort for my 2017 banding station birds. Except it turns out that we had too many cool birds this year to fit in one blog post, so I’ll be doing a series of banding station highlights posts. First up: the small and fuzzy.

Other lives

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.

Start looking

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.
