European Starling (Sturnus vulgaris)
I almost didn’t write about the European Starling as I dislike this species so much, but you might find the facts about this bird interesting.
This species is a native of Europe and is a member of rather large showy family of birds. Worldwide there are 76 species of starlings with the majority of them found in Africa, Asia, India and China. I have seen 15 species of starlings and some are very beautiful birds. The European Starling is no beauty in either the breeding or non-breeding plumage.
In 1890, sixty European Starlings were released into New York’s Central Park. The idea behind this introduction was to have all of the bird species in Shakespeare’s plays breeding in New York. Those 60 original individuals had spread to the west coast in less than 60 years. Unfortunately, in the process they usurped the habitat of many native species and forever changed avian populations in America. Starlings prefer the company of humans and do well in urban environments. Typically perches are power lines and roof edges. As the country side turned into urban environments starlings flourished and generally became a pest species. In a little more than a century this species grew from sixty individuals to more than an estimated 200,000,000 birds. They are aggressive cavity nesters and out compete native species for nesting sites. Bluebird, and woodpecker populations have been especially hard hit . Starlings are a colonial rooster and as many as a million birds have been known to occupy a roost site creating health issues that are hard to manage.
In Montana they breed state wide and overwinter in much of the state. In the upper Clark Fork Valley winter numbers are not large, but by April you begin to see flocks of several hundred. In the fall, migrating flocks can reach a thousand or more. Fall flocks often contain several species of blackbirds as well.
European Starlings are about the size of a meadowlark with an obvious short tail and sharply pointed large bill that is yellow in breeding and black in non-breeding birds. The breeding plumage is iridescent with faint white spots. Winter plumage shows a heavy speckling of white dots. The difference is enough that novice birders think the two plumages are separate species. Their song is a combination of harsh whistle, clicks, and chuckles. They often mimic other birds, and do an amazing imitation of a Red-tailed Hawk.
Eradication programs, have killed million of starlings by trapping and poisoning, but has had little effect on the total population. I am not aware of any major eradication programs having being conducted in Montana.
The next time you see a European Starling, realize that taking a species from one habitat and transplanting into another habitat has its risks. Without the natural predators that have developed with a species, over time the population can explode. An out-of-balance population can be a threat to native species. Fortunately, we have learned from our mistakes and rarely are species moved from one part of the world to another any longer.
