Common Starling

The starling appears exactly once in all of Shakespeare. Henry IV Part 1, Act 1, Scene 3, Hotspur is ranting about being denied permission to ransom a prisoner and says he will teach a starling to repeat the forbidden name until it drives the king insane. It is a throwaway line in a minor scene. The starling is not the point of the scene. The starling is not even the point of the sentence. Eugene Schieffelin read that line in 1890 and decided it was sufficient justification for introducing a new species to a continent. He released sixty common starlings in Central Park in March of that year and forty more in 1891. The first confirmed North American nesting occurred in the eaves of the American Museum of Natural History in 1896. By 1900, thousands of birds existed in the eastern states. By 1950, the range covered the continent. By 1980, an estimated two hundred million birds. From one hundred. In ninety years. Because of one line in a history play that most people skip. The native cavity-nesting birds that lost nest sites to the expanding starling population, the eastern bluebird, the purple martin, the red-headed woodpecker, were not consulted. They did not receive advance notice. They simply found their nest holes occupied by something that arrived before them, moved in, and has been breeding there ever since. The common starling (Sturnus vulgaris) has been a year-round resident across all 26 North Louisiana parishes for over a century. It runs one of the more interesting lives of any bird in the coverage area while most people dismiss it as a parking lot nuisance. One Shakespeare line. Two hundred million birds. The least you can do is pay attention to what it actually is. It Doesn't Actually Look Like a Blackbird (Look Closer) Common starlings get called blackbirds constantly, by casual observers, by people who should know better, occasionally in print, and the confusion is understandable at thirty yards with no binoculars but dissolves immediately with attention. The starling is aware that it has been miscategorized. The starling does not care. The short, triangular tail is the instant separator. Every grackle in North Louisiana has a long tail. Every Brewer's and rusty blackbird has a moderate tail with a rounded end. The starling has a tail that looks like something went wrong at the tail factory. In flight, the wings form a short triangular silhouette without the trailing edge sweep of a grackle, and the flight style is different too, direct, fast, without the rowing quality that characterizes most icterids. Then there's the seasonal plumage situation, which is one of the more genuinely remarkable things any North American bird does, and which the starling accomplishes without growing a single new feather. Fresh fall starlings are heavily spotted, each feather has a pale tip that covers the bird in a constellation of buffy-white dots, making it look completely different from a breeding adult. By spring, those tips have worn away through normal activity, exposing the iridescent base color underneath. Green and purple. Real, shifting iridescence that rivals a grackle in good light. The bird goes from spotted and winter-muted to glossy and spectacular through abrasion, not molt. No new feathers needed. The spring plumage was under the winter plumage the whole time, waiting. The bill changes seasonally too: dark in winter, yellow in spring. The bird carries a built-in calendar on its own face, which is either useful or unsettling depending on your relationship with the concept. In good morning light on a suburban utility wire in March, a common starling in breeding plumage is genuinely beautiful. This doesn't make up for the bluebird boxes. But it's true and it's available every morning. The Voice (Which Is More Interesting Than You Think, Once You Actually Listen) A singing starling in late winter, listened to closely instead of dismissed as general bird noise: Common starlings are vocal mimics. Their song has been running continuously since February and shows no signs of stopping. It is not a fixed repertoire, it is a continuously evolving mix of the starling's own sounds alongside borrowed phrases from other species in the immediate neighborhood. A starling on a territorial perch in February in Shreveport may be incorporating red-tailed hawk screams, killdeer calls, Carolina wren phrases, and eastern wood-pewee whistles into a single continuous performance. Individual birds develop location-specific repertoires by learning from the birds around them, which means the starling on your utility wire in February is performing a set that reflects everything within earshot of that wire since the previous fall. This is either impressive or alarming depending on how you feel about a bird knowing your neighborhood better than you do. The starling that sounds like it's doing a hawk impression near a red-tailed hawk territory learned that call from the actual red-tailed hawk next door. A starling delivering a perfect red-tailed hawk scream from a suburban utility wire has sent experienced birders scanning the sky for a hawk that is not there. Once. After that, you know to check the wire first. Once. It only needs to work once. After that, you know. The characteristic contact note, a descending whistle, slightly plaintive, is the sound you've been hearing in every parking lot and suburban neighborhood in North Louisiana without knowing what it was. Load it on Cornell's website and play it back in your yard. Watch how fast you recognize it. You've heard it a thousand times. Nobody told you it was worth knowing. The Cavity Competition Problem (And What to Do About It) The starling's early nesting season is not an accident. They start claiming cavities in late February or early March. The purple martins are still in South America. The starlings are already in the housing. The early arrival is the mechanism. By the time native species are ready to nest, the starlings have already claimed the best available real estate and laid eggs. The impact is real and documented. A bluebird trail without active management gets largely taken by starlings within a few seasons. The starlings are not apologetic about this. They are not aware it is a bluebird trail. Purple martin colonies need pre-season management to exclude starlings before scouts arrive. This is not hypothetical. Trail monitors track it. The numbers show it. Counter-strategies that work: entrance holes calibrated to bluebird dimensions (1.5 inches) physically exclude starlings while allowing bluebirds. Active monitoring and nest removal before eggs are laid interrupts establishment without harming the adult birds, removing a starling nest with eggs is legal and effective. Keeping purple martin housing closed until the first scouts arrive from South America eliminates the early-season nesting foothold. None of this means eliminating starlings from your property, which would be impossible. It means redirecting the competitive outcome in favor of the species that evolved here. The Murmuration (The Part That Makes No Sense Until It Does) Winter starling roosts in North Louisiana, sometimes hundreds of thousands of birds in bottomland tree stands alongside the native icterid species, deliver the murmuration behavior at dusk that has been studied with high-speed cameras and computational models and is still, frankly, a little inexplicable even after you understand it. Each bird responds to the movement of its six or seven nearest neighbors. Not the whole flock. Not a leader. Seven neighbors. The coordinated behavior of half a million birds emerges from that rule applied simultaneously everywhere in the flock, which is either elegant or deeply unsettling depending on your prior assumptions about how decisions get made. No bird leads. No bird has a view of the whole flock. The coordinated wave movements that propagate through a mass of hundreds of thousands of birds emerge from local rules applied simultaneously, everywhere in the flock at once. The result looks like a single vast organism making decisions. A hawk enters the mass and the shape contracts around it. The hawk can't track a single bird because the visual field is entirely composed of birds moving in all directions at once. The flock disperses the hawk's targeting through pure complexity. What this looks like from a road shoulder in Tensas Parish in December: the sky goes dark over the tree line. The mass shifts in shapes that feel designed. It builds and contracts and then collapses into the trees all at once. If you've never watched this with the specific knowledge that no bird is leading, the experience is difficult to describe to someone who hasn't had it. The apparent intelligence is real. The central intelligence directing it doesn't exist. The distributed rules of motion, followed by two hundred thousand birds simultaneously, deliver something that looks like thought. The starling didn't choose to colonize North America. It was carried here in a box by a Shakespeare enthusiast with more ambition than judgment. But the murmuration it deliver over a Louisiana bottomland in December was worth watching before the annotation, and it's worth watching after. Where to Find Common Starlings in North Louisiana You don't need to find them. They'll find you. Year-round, all 26 parishes, every agricultural landscape, every suburban neighborhood, every parking lot, every athletic field with short grass, every livestock operation. For the murmuration specifically, the eastern agricultural parishes during December and January hold the largest concentrations, often in mixed roosts with native blackbirds. The same rural roads in Tensas, Madison, and Morehouse Parishes that deliver mixed blackbird flocks deliver starlings. Watch for the pre-roost staging behavior at dusk, birds moving toward a common point from multiple directions, the mass growing at a fixed location above the tree line, and position yourself for the show. For breeding plumage in good light, any urban park or residential area with utility wires in late February through April. Morning light from the east, bird facing you or slightly angled, the iridescence firing across the body: give it thirty seconds before you dismiss it. The Murmuration: What Is Actually Happening The coordinated movement of large starling flocks at dusk has been studied with high-speed cameras and computational fluid dynamics, and the mechanism is specific enough to be worth knowing: each bird responds to the movement of its seven nearest neighbors with a slight lag and a bias toward maintaining local density. Not the whole flock. Not a leader. The seven birds immediately adjacent to any given bird. The coordinated wave movements that propagate through a mass of half a million birds emerge from those local rules applied simultaneously everywhere in the flock at once. This delivers something that looks like a single vast organism making decisions, but no bird is making decisions for the group. The hawk that enters a murmurating flock cannot isolate a target because the visual field fills entirely with birds moving in all directions simultaneously. The behavior evolved as predator defense. The fact that it looks like choreography from the road shoulder is coincidental to the physics that produce it. The North Louisiana winter roosts in the agricultural eastern parishes produce murmuration behavior at dusk as birds stream in and the mass forms above the roost trees before dropping in for the night. A roost of several hundred thousand birds at a bottomland timber stand in Tensas Parish in December is producing one of the genuinely extraordinary wildlife spectacles available in the coverage area, and most people who drive past it on their way somewhere else do not know what they are seeing. The Schieffelin Decision (One Man. One Play. Two Hundred Million Birds.) Eugene Schieffelin released sixty common starlings in Central Park in March 1890 and forty more in 1891. His stated motivation: introducing to North America every bird mentioned by Shakespeare. The starling's entire Shakespeare resume consists of one line in Henry IV Part 1, when Hotspur, furious at being denied permission to ransom a prisoner, says he would teach a starling to say the forbidden name repeatedly until it drove the king insane. It is a throwaway line in a political rant in a history play that most people skip entirely. Schieffelin apparently read this line and concluded it was sufficient grounds for permanently altering the avifauna of a continent. He was not a biologist. The outcome makes this clear. The first confirmed nesting was in the eaves of the American Museum of Natural History in 1896. By 1900, thousands existed in the eastern states. By 1950, the range covered the continent. By 1980, an estimated two hundred million birds. From one hundred. In ninety years. Because of a line in a history play that most people skip. The murmuration over a Louisiana bottomland in December was not part of Schieffelin's plan. The plan was literary. The physics of murmuration do not care. The Spotted Winter Bird (Same Bird, Different Outfit) The common starling in October looks nothing like the common starling in March. Fresh fall plumage carries pale tips on nearly every body feather, producing a dense constellation of white and buff spots over the dark base. Observers who know only the glossy breeding adult regularly misidentify the spotted fall bird as a different species. It is not. The spots are feather tips. By February the tips have worn away through normal activity, the iridescent base color emerges, and the bird that looked spotted and dull in October looks glossy and purposeful in spring. Not one new feather was grown. The spring plumage was underneath the winter plumage the whole time. The structural field marks that separate starlings from grackles work at both plumage stages: short triangular tail, triangular wing profile, fast direct flight without the rowing quality of grackles. A heavily spotted dark bird with a short triangular tail moving fast and directly over a Shreveport commercial corridor in November is a common starling in fresh fall plumage, wearing its winter outfit, en route to wherever it is roosting. The Cavity Competition in Practice Bluebird trail operators who monitor boxes weekly and remove starling nest material promptly before eggs are laid report consistently higher bluebird productivity than operators who check boxes monthly. The management works when applied consistently. The starling is not a problem solved once. It is an ongoing competitive pressure that ongoing management can shift in favor of native species at specific sites. Entrance holes sized to exactly 1.5 inches admit eastern bluebirds and physically exclude common starlings. This is the most reliable passive solution: the starling cannot enter a box with the correct entrance hole size, regardless of how persistent it is. Purple martin housing managed before the first scouts arrive in late February, before any starling has established residence in the housing, eliminates the early-season squatter advantage the starling exploits when housing sits unmonitored through winter. The starling is not going away. It has been established on this continent for over a century and the population shows no trajectory toward decline. Active management at the site level shifts specific outcomes. The species continues operating at the landscape level regardless. The Voice in Detail The common starling song is a continuous performance with no obvious repeating structure, which is the point and also makes it difficult to describe. The male is not singing a territorial sequence that repeats. He is producing an extended improvisation that incorporates mimicry from the surrounding soundscape, and he keeps going as long as he is on the territorial perch, which in late February and March can be twenty minutes without an obvious pause. The mimicry sits inside the song as discrete borrowed phrases: a few notes from the killdeer, then the starling's own material, then a red-tailed hawk scream, then something unidentifiable, then a Carolina wren figure. Each borrowed element lasts for a phrase or two and then the bird moves on to the next element. The overall impression is of a bird that has been recording the local soundscape all winter and is now playing back a scrambled version at territorial volume. Once you know to listen for the embedded mimicry, every singing starling in late February becomes an audio catalog of what has been living in its immediate vicinity since fall. The birds it has heard, the ambient sounds it has been tracking, the specific acoustic neighborhood it has been monitoring: all of it shows up in the song. The Carolina wren phrase from the starling on the utility wire means a, or was recently, a Carolina wren within earshot of that wire. The starling is not trying to tell you this. It is incidental. But it is accurate. Two Hundred Million From One Hundred One hundred birds in 1890. Two hundred million by the 1980s. This is what exponential growth looks like when a species finds a continent with abundant food, abundant nest sites, no specialized predators, and no competitors for its specific niche. The common starling found all four simultaneously in North America, which is either very lucky or a damning indictment of how thoroughly the eastern cavity-nesting community was unprepared for something that arrived early and moved fast. The doubling time ran roughly every five years across nine decades, which is what exponential population growth looks like when a species lands in an environment with abundant food, abundant nest sites, no specialized predators, and no significant competitors for its specific niche. The common starling found all four simultaneously. The cavity-nesting birds that the starling displaced, bluebirds, purple martins, red-headed woodpeckers, had occupied their nest sites for millions of years without encountering anything that competed for them the way starlings compete. They had no behavioral response to a species that could outcompete them for nest holes before they arrived in spring. The starling knew about arriving early. The bluebird did not know the starling existed. Two hundred million birds is what one hundred birds becomes when the conditions are exactly right. Schieffelin was thinking about Shakespeare. The starling was thinking about nest holes. Only one of them was right about what mattered. The Starling and North Louisiana The common starling has been in North Louisiana long enough that most residents have never known a North Louisiana without it. It has been here longer than many of the ornamental trees it nests in. It arrived before living memory and has made the species entirely at home in the meantime. The ecological damage it caused to native cavity-nesting birds in the decades after its establishment is historical. The ongoing competitive pressure on bluebird trails and martin colonies is current. The murmuration at a winter roost in the agricultural eastern parishes is, depending on when and where you see it, one of the more extraordinary wildlife experiences North Louisiana delivers. The mimicry in the late February song is genuinely interesting once you know to listen for it. The feeder behavior is efficient and occasionally irritating. All of these things are simultaneously and completely true about the same bird. The starling does not have a position on any of this. It is running its program. The program is working. One hundred birds in 1890. Two hundred million by 1980. The murmuration at dusk in Tensas Parish in December is what one hundred birds became over a century. Schieffelin was thinking about Shakespeare. The starling was thinking about nest holes. The Starling at the Feeder Starlings arrive at platform feeders in groups, eat efficiently, and leave. A no subtlety involved. The starling has never had any interest in appearing unobtrusive and does not begin at the feeder. It memorizes the refill schedule by the second week and adjusts its visits accordingly. This is either impressive or alarming depending on how you feel about a European introduction having a more consistent relationship with your feeder schedule than you do. The practical feeder management response: tube feeders with small perches or caged suet feeders exclude starlings by their size while admitting smaller native species. Platform feeders and open suet cages without caging do not exclude them. The starling reads the feeder type and adjusts accordingly. It has had this assessment completed within a week of any new feeder being installed in its territory. The common starling's efficiency at exploiting resources, feeders, nest boxes, agricultural settings, urban green space, is the expression of the same cognitive flexibility that made the species successful at colonizing a continent from a hundred individuals. The bird is good at finding food. It is good at using nest sites. It is good at avoiding being eaten. These qualities are not unique to starlings among birds, but the starling has them in a particular combination and applies them in a particular landscape with a particular consistency that has produced two hundred million birds from one hundred in under a century. None of that makes the starling welcome at the bluebird box. The bluebird box needs the 1.5-inch entrance hole. The murmuration needs an audience. The starling needs neither of these things and does not know about either requirement. It is running its own program, as it has been since 1890, as it will continue to run until conditions change in some way that significantly disadvantages the species. So far, conditions have not done that. The Mimicry You Did Not Expect The killdeer call that arrives from the utility wire when no killdeer is visible: check whether the starling is on that wire. The red-tailed hawk scream from a suburban tree when no hawk is circling: check the starling. The Eastern wood-pewee phrase that arrives out of season: check the starling. The species incorporates the local soundscape into its song with enough accuracy that experienced observers have been temporarily misdirected by it, looking for the source of a sound that turns out to be a starling doing a convincing impression of the source. The mimicry is learned, not inherited. A starling in Lincoln Parish has learned the sounds of Lincoln Parish, not the sounds of wherever it hatched. The song catalog it builds reflects the specific acoustic environment it has occupied since fall, which means a singing starling is a real-time audio record of the local bird community at that specific location over the preceding months. The information is embedded in the song whether or not anyone is listening for it. The Species That Was Not Asked For Nobody in North America in 1890 requested a common starling. The bluebirds were not lobbying for a competitor. The bluebirds are unavailable for comment on the subject. The starlings are also unavailable for comment, but for different reasons: they do not know about Shakespeare and have never been informed that a single line in a history play is the reason they exist on this continent. The purple martins were not looking for a squatter that would occupy their housing before they returned from South America and then contest eviction with a commitment that most tenants would find exhausting. The purple martins were not looking for something that would move into their housing before they returned from South America. The cavity-nesting bird community had been running without a starling in it for millions of years and had no gap that needed filling. Eugene Schieffelin supplied one anyway, on the basis of a line in a play about Henry IV's political problems, and now the gap that did not exist contains two hundred million birds. The bluebird populations are rebuilding slowly behind properly sized entrance holes. The bluebirds are unavailable for comment. The starlings are at the feeder. Schieffelin filled a gap that did not exist with a species that was not requested and produced two hundred million birds and a permanent restructuring of the cavity-nesting community across the continent. The murmuration in December is extraordinary. The cavity competition is real. The mimicry is genuinely interesting. The iridescence in breeding plumage is, in good morning light, beautiful. The starling is all of these things simultaneously, and none of the beauty or interest changes the fact that nobody asked for it. The 1.5-inch entrance hole. The weekly monitoring. The pre-season martin house management. These are the tools that work at the site level. The species continues at the landscape level regardless. One hundred birds in 1890. Two hundred million by 1980. The math was always going to run like this once the conditions were right. The starling did not ask for the conditions to be right. They were right. It was already there. The common starling is the most thoroughly established introduced bird in North Louisiana, present in every habitat, breeding in every parish with available cavities. It has been here longer than most residents have been alive. It has been assessed as a pest, documented as a fascinating ecological subject, and watched in murmurations that produce involuntary stops on rural roads in December. All three assessments are accurate. The bird is running its program regardless. One hundred birds in 1890. Two hundred million by 1980. The murmuration is worth watching. Accessibility Notes The common starling's descending contact whistle, a falling two-note call with a liquid quality, carries across suburban and open settings and identifies the species before any visual effort in the environments it concentrates in: parking lots, managed lawns, utility wires, suburban ornamental plantings. The sound is specific once learned and arrives year-round from every developed setting in the coverage area. The late February territorial song is worth specific attention for sound-first identification: a continuous improvisation incorporating mimicry from the local bird community, lasting several minutes without obvious repetition. The structure is different from any native songbird's song, longer and more variable, the mimicry embedded as phrases within the larger performance rather than as standalone imitations. The species is in every developed setting in all 26 parishes without any specialized habitat access. Suburban feeders, commercial areas, and agricultural field margins hold common starlings within sight and earshot of a parked vehicle throughout the year. Winter murmuration events at roost sites in the agricultural eastern parishes are visible from rural road shoulders, the mass audible before it is fully visible.

A Few More Facts

Accessibility Notes

The descending contact whistle carries across suburban and agricultural settings year-round. Once connected to the bird, it arrives from every utility wire, parking lot, and open lawn you ever visit for the rest of your life. Recognition is the work. The bird does the rest.

Suburban foraging flocks and breeding-season territorial males on utility wires and rooftops are visible from vehicle windows throughout the coverage area without specialized habitat access. The murmuration events at winter roost sites in the eastern agricultural parishes are audible and visible from rural road shoulders — the mass generates wingbeat sound at scale and the visual display requires no binoculars.

For bluebird trail operators and purple martin landlords: the active monitoring approach means visiting nest boxes regularly starting in late February, removing starling nest material promptly, and using entrance hole sizing as physical exclusion. The effort is not trivial but the results are measurable.
