People seem to either really like or loathe starlings. Videos of these creatures’ aerial maneuvers have become Internet sensations. On the other hand, agriculture officials frequently regard the birds as avis non grata, going so far as to employ mass extermination measures in the United States. What’s with both all the love and so much hate?
Those Amazing Murmurations
A murmuration, the name for a group of starlings, is an amazing sight, something my wife likens to a moving sculpture in the sky. “Murmuration” is also the title of a short online viral video posted a few years ago by Sophie Windsor Clive and Liberty Smith. In their footage, the young women are paddling in a canoe before coming across a sudden swarm of starlings. Their recorded close encounter immerses viewers in nature’s serendipitous beauty, each sweeping movement a spectacle of wonder. Watching the feathered formations bound in flight over Ireland’s River Shannon must have been something special. Fortunately, thanks to the Internet, we can partake in their experience vicariously.
“A Bird Ballet”, Neels Castillon’s short film from Marseille, France, evokes similar feelings of amazement. Both his and the “Murmuration” videos are professionally edited and include music. Occasionally, one hears the wowed responses of those shooting the footage. However, the rhythmic sky dance of starlings is so mesmerizing that I prefer watching with the sound muted. No enhancements necessary!
There’s nothing like seeing starlings fly en masse. In the poem “Starlings in Winter”, Mary Oliver refers to the birds as “acrobats”. She marvels at how “they float like one stippled star that opens, becomes for a moment fragmented, then closes again …” (1). Of course, she’s just one of many poets that these birds have fascinated. Once while watching a murmuration during a coach ride, Samuel Taylor Coleridge compared the shapeshifting formations to “smoke” and “mist”, always in flux, “… expanding or contracting, thinning or condensing … thickening, deepening, blackening!” (2).
Thousands of these creatures engage in ever-changing flight maneuvers somehow without getting tangled and crashing—that’s the spectacular thing about murmurations! How do these birds do this? In the 2014 book The Thing with Feathers, ornithologist Noah Strycker devotes an entire chapter to starling flocks. There he discusses how a collection of the birds form a magnetic system while in flight, and why the number seven is significant in this process. Due to these discoveries, researchers can now generate models that successfully predict the aerial patterns of a murmuration based on its size (3).
For Many, Still Avis Non Grata
Strycker touches as well on humans’ love-hate relationship with starlings. He writes about the “Murmuration” video that garnered millions of views in just a matter of days, and also of Google search results easily confirming starlings as “America’s most hated bird” (4). Only introduced to North America in 1890, the European starling ranks today among the ten most populous avian species on the continent. With millions migrating across the country, starlings are generally regarded as an invasive pest. Strycker questions whether the birds deserve their negative reputation (5). Nevertheless, for nearly 50 years, a pesticide has been employed to poison these birds. It’s a practice that continues to this day.
A few weeks ago, the Associated Press reported that multitudes of dead starlings had been discovered in the northern parts of Nevada. At first, many residents were uncertain as to what had happened to the birds. People learned later, though, that the United States Department of Agriculture had used DRC-1339, a chemical sometimes referred to as Starlicide, to kill them. In that article, an official provides the rationale for the baiting and extermination of the starlings: “Bird feces can contaminate food and water sources, putting cattle at risk for salmonella and E. coli infections if ingested” (6). In short, the measure was performed for the sake of public safety.
The U.S. has used this chemical since 1967 to kill starlings. Once ingested, the agent quickly damages a bird’s heart and kidneys, often resulting in death within one to three days. Officials have also employed DRC-1339 to control populations of pigeons, mynas, gulls, blackbirds, ravens, crows, and other birds (7, 8, 9). Proponents of the compound tout that its toxicity is quickly degraded by exposure to sunlight and moisture. Also, most raptors, with the exception of owls, are not sensitive to the chemical. So birds of prey, as well as many mammals, that may consume the dead starlings are deemed safe. Cats, however, are at risk, and research indicates that the chemical can be “moderately toxic to fish” (10).
A Balancing Act
Several animal organizations continue to frown upon employing DRC-1339 baits. Both the National Audubon Society (11, 12) and the Humane Society of the United States (13, 14) have been critical of its use. Despite claims that DRC-1339 is relatively safe, questions remain, especially regarding whether such mass-killing measures are warranted. And the debate looks to continue, especially with the recent bad publicity in Nevada. In the balance hangs the considerate treatment of wildlife on one hand and the wellbeing of cattle and crops on the other.
Starlings are marvelous beings, easily adapting to and flourishing in new environments. While their feathered formations awe many folks, the birds still provoke fear and revulsion in others. The dynamics of how humanity perceives these creatures persist in closely bound, twisting motions just like their flight patterns. Acrobats indeed.
