We’re at the end of National Invasive Species Awareness Week, and today we’re going to look at a species you probably see every day: the European starling.
These birds were intentionally released in a number of places throughout North America, but one of the most common stories is that the president of the American Acclimatization Society, Eugene Schieffelin, introduced 60 starlings into New York’s Central Park in 1890. It is rumored that he intended to introduce all bird species mentioned in the works of William Shakespeare to North America, but we don’t really know for certain.
What we do know is that, since then, the number of European starlings in North America has grown to an estimated 150 million. They can be found from Alaska and southern Canada all the way down to Central America, and from the east coast to the west. They’re everywhere.
These noisy birds can be found in all areas: wilderness, agricultural, suburban, and urban environments. The build rough nests of sticks or stems in any sort of hole: large business signs, cracks in walls, under eaves, on cliff faces. They are omnivorous, eating anything, including garbage; they often contaminate more than they consume. When they gather in large numbers, their droppings can accumulate.
They tend to be territorial during breeding seasons, but in the winter they will congregate into massive flocks that may number up to a million birds. These large flocks of birds sometimes form what’s called a murmuration – an aerial display in which the birds engage in complex and synchronized patterns. The flock appears to move as a single unit, expanding and contracting, flowing back and forth. It may serve to deter predators or even as sharing information on roosting sites.
There isn’t a lot anyone can do about invasive starlings. They are too numerous and too well-established. At most, you can prevent them from nesting on your property or destroy their nests if they do – just be sure it is really a starling nest and not one belonging to a native species.
Thank you for joining us this week for a look at some of the invasive species found in Kansas! We hope you found our posts informative and educational.
