While the little family is being reared, or, indeed, at any time, no one is wise enough to estimate the millions of tiny insects from the garden that find their way into the tireless bills of these wrens.
It is often said that the house wren remains at the north all the year, which, though not a fact, is easily accounted for by the coming of the winter wrens just as the others migrate in the autumn, and by their return to Canada when Jenny wren makes up her feather-bed under the eaves in the spring.
CAROLINA WREN (Thryothorus ludovicianus) Wren family Called also: MOCKING WRENLength -- 6 inches. Just a trifle smaller than the English sparrow Male and Female -- Chestnut-brown above. A whitish streak, beginning at base of bill, passes through the eye to the nape of the neck. Throat whitish. Under parts light buff-brown Wings and tail finely barred with dark.
Range -- United States, from Gulf to northern Illinois and Southern New England.
Migrations -- A common resident except at northern boundary of range, where it is a summer visitor.
This largest of the wrens appears to be the embodiment of the entire family characteristics: it is exceedingly active, nervous, and easily excited, quick-tempered, full of curiosity, peeping into every hole and corner it passes, short of flight as it is of wing, inseparable from its mate till parted by death, and a gushing lyrical songster that only death itself can silence. It also has the wren-like preference for a nest that is roofed over, but not too near the homes of men.
Undergrowths near water, brush heaps, rocky bits of woodland, are favorite resorts. The Carolina wren decidedly objects to being stared at, and likes to dart out of sight in the midst of the underbrush in a twinkling while the opera-glasses are being focussed. To let off some of his superfluous vivacity, Nature has provided him with two safety-valves: one is his voice, another is his tail. With the latter he gesticulates in a manner so expressive that it seems to be a certain index to what is passing in his busy little brain -- drooping it, after the habit of the catbird, when he becomes limp with the emotion of his love-song, or holding it erect as, alert and inquisitive, he peers at the impudent intruder in the thicket below his perch.
But it is his joyous, melodious, bubbling song that is his chief fascination.
He has so great a variety of strains that many people have thought that he learned them from other birds, and so have called him what many ornithologists declare that he is not -- a mocking wren. And he is one of the few birds that sing at night -- not in his sleep or only by moonlight, but even in the total darkness, just before dawn, he gives us the same wide-awake song that entrances us by day.
WINTER WREN (Troglodytes biemalis) Wren family Length -- 4 to 4.5 inches. About one-third smaller than the English sparrow. Apparently only half the size.
Male and Female -- Cinnamon-brown above, with numerous short, dusky bars. Head and neck without markings. Underneath rusty, dimly and finely barred with dark brown. Tail short.
Range -- United States, east and west, and from North Carolina to the Fur Countries Migrations -- October, April. Summer resident. Commonly a winter resident in the South and Middle States only.
It all too rarely happens that we see this tiny mouse-like wren in summer, unless we come upon him suddenly and overtake him unawares as he creeps shyly over the mossy logs or runs literally "like a flash" under the fern and through the tangled underbrush of the deep, cool woods. His presence there is far more likely to be detected by the ear than the eye.
Throughout the nesting season music fairly pours from his tiny throat; it bubbles up like champagne; it gushes forth in a lyrical torrent and overflows into every nook of the forest, that seems entirely pervaded by his song. While music is everywhere, it apparently comes from no particular point, and, search as you may, the tiny singer still eludes, exasperates, and yet entrances.
If by accident you discover him balancing on a swaying twig, never far from the ground, with his comical little tail erect, or more likely pointing towards his head, what a pert, saucy minstrel he is! You are lost in amazement that so much music could come from a throat so tiny.
Comparatively few of his admirers, however, hear the exquisite notes of this little brown wood-sprite, for after the nesting season is over he finds little to call them forth during the bleak, snowy winter months, when in the Middle and Southern States he may properly be called a neighbor. Sharp hunger, rather than natural boldness, drives him near the homes of men, where he appears just as the house wren departs for the South. With a forced confidence in man that is almost pathetic in a bird that loves the forest as he does, he picks up whatever lies about the house or barn in the shape of food-crumbs from the kitchen door, a morsel from the dog's plate, a little seed in the barn-yard, happily rewarded if he can find a spider lurking in some sheltered place to give a flavor to the unrelished grain. Now he becomes almost tame, but we feel it is only because he must be.
The spot that decided preference leads him to, either winter or summer, is beside a bubbling spring. In the moss that grows near it the nest is placed in early summer, nearly always roofed over and entered from the side, in true wren-fashion; and as the young fledglings emerge from the creamy-white eggs, almost the first lesson they receive from their devoted little parents is in the fine art of bathing. Even in winter weather, when the wren has to stand on a rim of ice, he will duck and splash his diminutive body. It is recorded of a certain little individual that he was wont to dive through the icy water on a December day. Evidently the wrens, as a family, are not far removed in the evolutionary scale from true water-birds.
