The shrike is a citizen of the world, being found in both hemispheres. It does not appear that the European species differs essentially from our own. In Germany he is called the nine-killer, from the belief that he kills and sticks upon thorns nine grasshoppers a day.
To make my portrait of the shrike more complete, I will add another trait of his described by an acute observer who writes me from western New York. He saw the bird on a bright midwinter morning when the thermometer stood at zero, and by cautious approaches succeeded in getting under the apple-tree upon which he was perched. The shrike was uttering a loud, clear note like clu-eet, clu-eet, clu-eet, and, on finding he had a listener who was attentive and curious, varied his performance and kept it up continuously for fifteen minutes. He seemed to enjoy having a spectator, and never took his eye off him. The observer approached within twenty feet of him. “As I came near,” he says, “the shrike began to scold at me, a sharp, buzzing, squeaking sound not easy to describe. After a little he came out on the end of the limb nearest me, then he posed himself, and, opening his wings a little, began to trill and warble under his breath, as it were, with an occasional squeak, and vibrating his half-open wings in time with his song.” Some of his notes resembled those of the bluebird, and the whole performance is described as pleasing and melodious.
This account agrees with Thoreau’s observation, where he speaks of the shrike “with heedless and unfrozen melody bringing back summer again.” Sings Thoreau:–
“His steady sails he never furls
At any time o’ year,
And perching now on winter’s curls,
He whistles in his ear.”
But his voice is that of a savage,–strident and disagreeable.
I have often wondered how this bird was kept in check; in the struggle for existence it would appear to have greatly the advantage of other birds. It cannot, for instance, be beset with one tenth of the dangers that threaten the robin, and yet apparently there are a thousand robins to every shrike. It builds a warm, compact nest in the mountains and dense woods, and lays six eggs, which would indicate a rapid increase. The pigeon lays but two eggs, and is preyed upon by both man and beast, millions of them meeting a murderous death every year; yet always some part of the country is swarming with untold numbers of them. [Footnote: This is no longer the case. The passenger pigeon now seems on the verge of extinction (1895).] But the shrike is one of our rarest birds. I myself seldom see more than two each year, and before I became an observer of birds I never saw any.
In size the shrike is a little inferior to the blue jay, with much the same form. If you see an unknown bird about your orchard or fields in November or December of a bluish grayish complexion, with dusky wings and tail that show markings of white, flying rather heavily from point to point, or alighting down in the stubble occasionally, it is pretty sure to be the shrike.

Nature never tires of repeating and multiplying the same species. She makes a million bees, a million birds, a million mice or rats, or other animals, so nearly alike that no eye can tell one from another; but it is rarely that she issues a small and a large edition, as it were, of the same species. Yet she has done it in a few cases among the birds with hardly more difference than a foot-note added or omitted. The cedar-bird, for instance, is the Bohemian waxwing or chatterer in smaller type, copied even to the minute, wax-like appendages that bedeck the ends of the wing-quills. It is about one third smaller, and a little lighter in color, owing perhaps to the fact that it is confined to a warmer latitude, its northward range seeming to end about where that of its larger brother begins. Its flight, its note, its manners, its general character and habits, are almost identical with those of its prototype. It is confined exclusively to this continent, while the chatterer is an Old World bird as well, and ranges the northern parts of both continents. The latter comes to us from the hyperborean regions, brought down occasionally by the great cold waves that originate in those high latitudes. It is a bird of Siberian and Alaskan evergreens, and passes its life for the most part far beyond the haunts of man. I have never seen the bird, but small bands of them make excursions every winter down into our territory from British America. Audubon, I believe, saw them in Maine; other observers have seen them in Minnesota. It has the crest of the cedar-bird, the same yellow border to its tail, but is marked with white on its wings, as if a snowflake or two had adhered to it from the northern cedars and pines. If you see about the evergreens in the coldest, snowiest weather what appear to be a number of very large cherry-birds, observe them well, for the chances are that visitants from the circumpolar regions are before your door. It is a sign, also, that the frost legions of the north are out in great force and carrying all before them.
