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.

Planet Earth II, the new BBC documentary narrated by Supreme Voice of Nature Sir David Attenborough, devotes one of its six episodes to animals living in cities. It’s unsurprisingly great. (Even if the ultimate masters of urban living, pigeons, who you might expect to be celebrated in this context, instead spend the episode getting unceremoniously eaten.) The “Cities” episode has to walk a delicate line, heralding animals’ ability to adapt to human landscapes without failing to acknowledge that humans overwhelmingly destroy habitat rather than creating it. It mostly leans to the optimistic side of the line; one segment makes New York City seem like a wildlife paradise.
The darker side of cities is represented by a segment on hatchling sea turtles. The turtles use the shine of moonlight on water to guide them from their nest in the sand into the ocean. Unfortunately, we humans love to shine lights even brighter than the moon, and more than half of the tiny turtles are drawn away from the ocean by the city’s lights.

As Attenborough narrates, footage rolls of the baby sea turtles gamely clambering across sidewalks and onto busy streets, heading for the ocean that isn’t there. The bodies of roadkilled turtles are visible in the background. One turtle makes it across the street, then tumbles halfway into a storm grate and gets stuck, lost to view save for one forlornly-waving flipper.
As soon as the episode ended, I began typing into Google: “planet earth 2 did”—at which point Google helpfully autocompleted the rest of the sentence: “planet earth 2 did they help the turtles“. Everyone else who had seen the episode wanted to know, too.
When I was kid, I thought I didn’t like cats. It didn’t help that every time I got near one, my eyes got itchy and my nose ran. My cat allergy disappeared around the time I went to college, where I volunteered at the local animal shelter and got a new perspective on felines. In the second year of my PhD program, I went to the East Bay SPCA and adopted a 3-year-old former stray.
I love my cat. She is 40% sweetheart, 40% terror, and 20% judgmental staring statue.
It looks like I’m sleeping, but I am watching your every move.
I am an ecologist, an ornithologist, and a bird-lover, so I know some things about cats that a lot of cat lovers may not. It all adds up to this: humans have put cats into an ecological trap, and we continue to do so, often with the best of intentions. It is not the cats’ fault. It is our human duty to get them out of this trap, for the cats’ sakes and for wildlife.
This is the Black Robin (Petroica traversi), a species found only in the Chatham Islands, New Zealand:

This was the total world population of Black Robins in 1980:
Five birds. That’s not great—and it gets worse. Guess how many of those were adult females?
Almost any conservationist would tell you that this was a hopeless situation. You can’t restart a species from one female—especially when that female is a whopping eight years old already, in a species that generally lives four years.
