STARLING (Sturnus vulgaris)

[Called also: EUROPEAN STARLING, AOU 1998]

Length -- 8 to 9 inches. Weight about equals that of robin, but

the starling, with its short, drooping tail, is chunkier in

appearance.

Male -- Iridescent black with glints of purple, green, and blue.

On back the black feathers, with iridescence of green and

bronze, are tipped with brown, as are some of the tail and wing

feathers. In autumn and early winter feathers of sides of head,

breast, flanks and underparts are tipped with white, giving a

gray, mottled appearance. During the winter most of the white

tips on breast and underparts wear off. Until the first moult

in late summer the young birds are a dark olive-brown in color,

with white or whitish throat. These differences in plumage at

different seasons and different ages make starlings hard to

identify. Red-winged blackbirds and grackles are often mistaken

for them. From early spring till mid-June, starling's rather

long, sharp bill is yellow. Later in summer it darkens. No

other black bird of ours has this yellow bill at any season.

Female -- Similar in appearance.

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 1 1/2 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?
