Shakespeare to Blame for Introduction of European Starlings to U.S.

Brought here on a lark, starlings are now at every turn

Whistle. Pop. Whirrrr. Zzzt. Repeat. Many, many, many times.

That’s the song, if you want to call it that, of the European starling. Two of these relatively drab, chunky little birds are now my next-door neighbors—the pair moved into a hole in the maple tree in front of my house. Whistle. Pop. Whirrrr. Zzzt. Repeat. Incessantly. They fly into the hole. They fly out of the hole. They dig away at the tree’s innards and fling the detritus onto the sidewalk below with their little yellow beaks. I might be grateful if I could count on the birds to toss sawdust onto freshly fallen snow so that pedestrians got a firmer footing. But it’s already spring; the birds are just digging a deeper hole for themselves.

Like an asteroid put on a collision course with the earth millions of years ago, the starlings invaded my territory because of events set in motion in the distant past. About a decade ago the top of the main trunk of the maple became diseased and saw the business end of a chainsaw. That left a dead top, the kind that cavity-nesting birds love to excavate to build their little homes. Only about 20 feet from the front door of my little home in the Bronx. Zzzt.

The other starting point lies much deeper in the mists of time. In the late 1590s Shakespeare noted the mimicking ability of the starling while writing Henry IV, Part 1. Hotspur is contemplating driving King Henry nuts by having a starling repeat the name of Hotspur’s brother-in-law Mortimer, whom Henry refuses to ransom out of prisoner status. “Nay, I’ll have a starling shall be taught to speak nothing but ‘Mortimer,’ ” Hotspur whines. (In theater and life, in-laws can often be counted on for dramatic conflict.) Whirrrr.

We move on to the late 19th century, when a group called the American Acclimatization Society was reportedly working on their pre-environmental-impact-statement project to introduce to the U.S. every bird mentioned in Shakespeare’s scripts. Clearly, the Bard abided birds—his works include references to more than 600 avian species. A Bronx resident, drug manufacturer Eugene Schieffelin (a street bearing his name isn’t far from my house) seems to be particularly responsible for the starlings’ arrival here. Well, his chickens have come home to roost. Pop. (The society also brought the house sparrow to our shores, a pair of which nest in a vent on the front of my other, human, next-door neighbor’s house.)

The Acclimatization Society released some hundred starlings in New York City’s Central Park in 1890 and 1891. By 1950 starlings could be found coast to coast, north past Hudson Bay and south into Mexico. Their North American numbers today top 200 million. As bird-watcher Jeffrey Rosen put it in a 2007 New York Times article, “It isn’t their fault that they treated an open continent much as we ourselves did.” Zzzt.

So why are starlings so little loved? Their looks don’t help: short, stocky and dark with light speckles, they look like chocolate that’s been left out for a few days. And have I mentioned their obnoxious series of sounds, er, song? Another strike against them is their competition with native birds that also make nests in handy cavities. Starlings have thereby been oft indicted as a major reason for the decline of the strikingly beautiful eastern bluebird, state bird of New York and Missouri. (The state bird of Missouri is not the cardinal?)

But perhaps starlings aren’t so bad. When the sun hits their feathers just right, they do have a certain iridescent attractiveness. And they have fascinating jaws. That’s right, jaws. Most of the world’s starlings have conventional jaws that close firmly. But our imported starlings’ jaws are wired completely differently—their musculature enables the beak to strongly open. According to The Birder’s Handbook, “the closed bill is inserted between blades of grass in thick turf or other cover, and then sprung open to expose hidden prey.” Which get to observe the unusual musculature of the jaw from the inside. Pop.

    Thank you for absolving the imported starlings from the horrific reputation foisted upon them by millions of backyard birders. You would think from the way that they are reviled that they were to blame for every songbird decline but for global warming. I love starlings, and have had several as rehab birds or staying on as pets. Their acrobatics are amusing, their ability to imitate sounds is astounding and because thy are considered nuisance birds it is permissable to adopt an abandoned baby bird to raise for release or as a pet. My daughter taught one of our rehab starling s to whistle "Colonel Bogeys March" ( think "Bridge on the River Kwai") The starlings at my back yard feeder are as entitled to the bird seed and suet as the native cardinals, orioles, and finches and the also imported house sparrows seem to hold thier own against the larger birds as well. check out the website at http://www.starlingtalk.net/ for more info on these clever and much maligned birds.

    During a time that I lived in a particularly ugly, industrial area of Greenpoint Brooklyn, one of the few birds I saw from my fire escape, apart from pigeons, was a little starling who used to come out and sun itself on the telephone wires. When you are deprived of more beautiful birds you learn to appreciate a seemingly lesser bird. It was quite animated as it preened and danced while belting out it's little song. I used to look forward to seeing it because it was cheery and seemed genuinely happy to be alive...

    The title is unfair to Shakespeare. All he did was state that Starlings are annoying. Why could he have any inkling that someone would say "Shakespeare says starlings are annoying. We need to have some"?

    The cardinal is also the state bird of North Carolina.

    THe tranfer of species from one eco-system to another is always a bad idea. Here in Ireland we are plagued by introduced American Grey Squirrels (during a wedding breakfast only 100 years ago believe it or not) who are out competing the retiring native reds. Though the worst example of damage caused by species tranfer has surely got to be that of European Homo Sapiens to the North American Continent in or around 1492
