Oklahoma State University has lined home windows on two of its largest buildings with polka dots.
Those adornments aren’t to make the buildings cuter — they’re to guard birds who would possibly in any other case fly into the broad reflective surfaces.
Up to a billion birds die every year within the United States after flying into home windows. Ecologist Scott Loss decided that quantity when he was learning chook mortality throughout the nation on the Smithsonian Institute. Now, he’s a professor in OSU’s Department of Natural Resource Ecology and Management, and he’s working with a staff of researchers to grasp and stop chook deaths on campus.
“Some of the species that fly with buildings here in town and on campus and around Oklahoma are in really steep decline population-wide,” Loss mentioned.
Tim O’Connell, another OSU ecologist, can also be main the college’s efforts to stop bird-building collisions. He began monitoring bird-window collisions thirty years in the past and was shocked to seek out the victims had been largely from out-of-town.
“Some of these are birds that would be spending the summer breeding in the isolated boreal forest, and where they overwinter might be like some mid mountain slope and Columbia,” O’Connell mentioned. “And then where they were dying was this like corporate office park.”
When O’Connell moved to Stillwater, individuals who knew about his analysis would inform him about useless birds they noticed on campus.
“The place where I noticed that there were a lot of dead birds showing up on campus was this Noble Research Center,” O’Connell mentioned. “It’s a pretty sprawling building on campus and it just has a lot of glass, kind of a modern architecture.”
Today, a number of big glass facades of the Noble Research Center are festooned with a grid of small white dots, concerning the measurement of a pencil eraser. Those dots are each part of Loss and O’Connell’s analysis and an funding in chook well-being on OSU’s campus.
From 2015 to 2017, a graduate scholar walked perimeters round campus buildings, scanning the bottom for useless or injured birds. That surveillance revealed birds had been significantly vulnerable to colliding with home windows on the Noble Research Center and the Gallagher-Iba Arena.
The college paid $78,000 to put in the dotted window movie, plus one other $40,000 to help a graduate scholar who will monitor these buildings to see how properly the movie works. When the college beforehand put in this movie at their glass bus cease shelters, it decreased chook deaths by about 70%.
Loss mentioned bird-baiting buildings aren’t distinctive to OSU, however he’s glad to see the college taking management on addressing the issue.
“When there’s big glassy buildings, there’s going to be dead birds under them,” Loss mentioned. “So it happens, I would wager to say, in virtually every college and university campus around the U.S., if not worldwide.”
Of course, birds can collide with any window. Especially with larger, shinier surfaces, birds see mirrored foliage and fly straight into it.
As you’d count on, this occurs loads at dazzling glass skyscrapers. But analysis exhibits smaller buildings additionally contribute to the demise toll.
“We think that the smaller buildings are probably cumulatively having a much bigger impact,” O’Connell mentioned. “It’s just the bigger ones are more showy, because you need a shovel to actually collect the birds that show up on a given day.”
While OSU is in search of options for medium-sized buildings, most individuals could make their properties and workplaces a bit bit safer for birds.
“We have hundreds of millions of individual residences in this country,” Loss mentioned. “And even if each of those only kills one or two birds per year on average, it adds up.”
If you’ve ever heard a ka-thunk and located a feathered fatality in your arms, there are a few steps you can take to cease it from occurring once more.
Loss and O’Connell each talked about that Feather Friendly film, which they used on the campus home windows and bus stops, is accessible for smaller home windows too. But any dots or decals will work, so long as they’re organized in a 2-inch-by-2-inch grid on the window’s exterior floor. People may set up exterior screens or stretch paracord alongside the size of a window.
“That moves in the breeze a little bit and lets birds know, hey, that’s something different,” O’Connell mentioned. “And that seems to be pretty effective — very low budget, very easy to install.”
And Loss mentioned simply turning off lights or closing blinds at night time might help, since brightly lit home windows can disorient birds, which regularly by the celebs to keep away from daytime predators.
Taking steps to guard birds can have a ripple impact on the setting.

“They are out there removing generally leaf chewing insects from plants in agricultural systems,” O’Connell mentioned. “That means they’re helping regulate the populations of grasshoppers and other things that might be agricultural pests in forest systems.”
He additionally mentioned birds assist the financial system — birding is likely one of the high 5 outside actions that encourage individuals to journey.
As many chook species are in decline, these advantages may begin to diminish too.
“This is really one of the ways that we can start to address those declines,” Loss mentioned. “It’s a low-hanging fruit, so we’re going to treat our windows to reduce the numbers of those birds that die in collisions.”
