Range—Massachusetts to Maryland. Not common beyond 100 miles inland. (Native of northern Europe and Asia.)
Migrations—Permanent resident, but flocks show some tendency to drift southward in winter.
This newcomer to our shores is by no means so black as he has been painted. Like many other European immigrants he landed at or near Castle Garden, New York City, and his descendants have not cared to wander very far from this vicinity, preferring regions with a pretty numerous human population. The starlings have increased so fast in this limited region since their first permanent settlement in Central Park about 1890 that farmers and suburban dwellers have feared that they might become as undesirable citizens as some other Europeans—the brown rat, the house mouse, and the English sparrow. But a very thorough investigation conducted by the United States Bureau of Biological Survey (Bulletin No. 868, 1921) is most reassuring in its results.
Let us first state the case for the prosecution: (1) the starling must plead guilty to a fondness for cultivated cherries; (2) he is often a persecutor of native birds, like the bluebird and flicker; (3) his roosts, where he sometimes congregates in thousands in the autumn, are apt to become public nuisances, offensive alike to the eye, the nose and the ear.
But these offences are not so very serious after all. He does not eat so many cherries as our old friend the robin, though his depredations are more conspicuous, for whereas the robins in ones and twos will pilfer steadily from many trees for many days without attracting notice, a crowd of starlings is occasionally observed to descend en masse upon a single tree and strip it in a few hours. Naturally such high-handed procedure is observed by many and deeply resented by the owner of the tree, who suffers the steady but less spectacular raids of the robins without serious disquiet.
Less can be said in defense of the starling's scandalous treatment of some native birds. "Unrelenting perseverance dominates the starling's activities when engaged in a controversy over a nesting site. More of its battles are won by dogged persistence in annoying its victim than by bold aggression, and its irritating tactics are sometimes carried to such a point that it seems almost as if the bird were actuated more by a morbid pleasure of annoying its neighbors than by any necessity arising from a scarcity of nesting sites….
"In contests with the flicker the starling frequently makes up in numbers what disadvantage it may have in size. Typical of such combats was the one observed on May 9, at Hartford, Conn., where a group of starlings and a flicker were in controversy over a newly excavated nest. The number of starlings varied, but as many as 6 were noted at one time. Attention was first attracted to the dispute by a number of starlings in close proximity to the hole and by the sounds of a tussle within. Presently a flicker came out dragging a starling after him. The starling continued the battle outside long enough to allow one of its comrades to slip into the nest. Of course the flicker had to repeat the entire performance. He did this for about half an hour, when he gave up, leaving the starlings in possession of the nest….
"Economically considered, the starling is the superior of either the flicker, the robin, or the English sparrow, three of the species with which it comes in contact in its breeding operations. The eggs and young of bluebirds and wrens may be protected by the use of nest boxes with circular openings 1½ inches or less in diameter. This leaves the purple martin the only species readily subject to attack by the starling, whose economic worth may be considered greater than that of the latter, but in no case was the disturbance of a well-established colony of martins noted."
As for the nuisance of a big established roost of starlings, it may be abated by nightly salvos of Roman candles or blank cartridges, continued for a week or at most ten days.
So much for the starling in his aspect as an undesirable citizen. Government investigators, by a long-continued study, have discovered that his good deeds far outnumber his misdemeanors. Primarily he feeds on noxious insects and useless wild fruits. Small truck gardens and individual cherry trees may be occasionally raided by large flocks with disastrous results in a small way. But on the whole he is a useful frequenter of our door-yards who pays his way by destroying hosts of cut-worms and equally noxious insects. "A thorough consideration of the evidence at hand indicates that, based on food habits, the adult starling is the economic superior of the robin, catbird, flicker, red-winged blackbird, or grackle." Need more be said for him?
