The Starling

(_Sturnus vulgaris_)

_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?
