They are intensely interesting from their habit of constructing several nests but one of which is utilized for housekeeping. After the real nest is made and the first egg laid, the male stays closely at home busying itself with building several nests, which are to all appearances entirely superfluous. In locating these he does not go beyond the immediate neighborhood of the true nest.
Some have thought that these sham nests are used as hiding places for the male, a Lilliputian watch tower or guard house, from which close watch is kept over the home property. Whether Mrs. Marsh Wren really needs such close watching, being more inclined to flirt than the ordinary feathered spouse, or because she is a better wife, so infinitely precious that she must be guarded from every side, is, as yet, an unsolved question. “Love holds the key to all unknown,” and though there is little to admire in a deportment made fine by compulsory measures, no doubt both parties understand the situation, which is quite enough for practical purposes. These nests, conspicuous from their size and exposed position, are securely attached to the upright swaying reeds, some of which penetrate their substance. They are lined with soft grasses and have an entrance at one side, often nearer the bottom than the top. Mr. Burroughs, who has found the marsh wren’s nest surrounded by half a dozen make-believes, says the gushing, ecstatic nature of the bird expresses itself in this way. It is simply so full of life and joy and of parental instinct that it gives vent to itself in constructing sham nests; the generous-hearted creature being willing to build and support more homes than can be furnished or utilized.
Entering the Lake Shore drive at St. Albans Bay, where dense tangles border the swamp beyond, you are sure to hear a song that is unmistakably wrennish. You have glimpses also of a small brown bird bubbling over with a nervous energy that betrays itself in every note he utters. Wait quietly and he approaches, but go one step in his direction and he recedes to the swamp where human foot may not follow.
Push your boat up the creek, the only avenue leading to his abode, that tantalizing song leading on meanwhile like the Pied Piper of Hamelin, though unlike the latter there is no disillusioning at the end. Red-winged blackbirds take wing as you enter the twilight of soft green and amber shade and the far-off music of their jangle-bells becomes less musical, the males striving “to recommend themselves by music, like some awkward youth who serenades his mistress with a jewsharp,” and using the air or the alder tops as a parade ground upon which to exhibit their musical evolutions. And yet you are witness to many a voluntary bit of sentiment that will increase your interest in this scarlet epauletted regiment, descendants of the dusky tribe that anchored long ago in this peaceful haven, going out and coming in with the tide until the legend of their coming is as vague and shadowy and misty as that of the golden-fleece voyageurs—the Argonauts. They ebbed and flowed with the stream; came at the proper time and season without knowing why; anchored and launched their ebony ships when it was time for sailing.
Here and there along this waterway the branches clasp hands above the creek, forming an arch of green within which vines sufficiently elegant to warrant exclusiveness cling in unaffected grace to the alders, without inquiring or caring as to the pedigree of their support. It is sufficient for them that the support is there.
A whole half mile along the stream and trees and bushes disappear, leaving a dense mass of reeds, the marsh wren’s “ain countrie,” out of which he is never at his best and to which he gives you no welcome.
Birds, like persons, have wonderful powers of concentration upon one topic, woe be to you if that topic happens to be yourself!
Every denizen of the swamp regards you with suspicion, watching each movement as closely as if you were a dangerous character traveling under an alias, and could not be trusted to sail upon this ruddy ocean in which their lordships have anchored their private yachts. Push your boat far in among the reeds and cat-tails, into the sea of shadows over which no sluggish current sends a ripple, and certain globular nests in the tangled reeds reward your search. Push your fingers within these nests and in one only, here and there, will you find from five to ten dark eggs, a rich reward for all your trouble.
Meanwhile the “neighbors,” and the marsh wren generally has numbers of them, have doubtless been charming you with their bubbling, gurgling song, always half the colony singing at once, or, one bird rising above the reeds gives the order, as it were, and the whole colony joins in the chorus. The song is quite beyond their control; they seem filled to overflowing with an inexhaustible supply of music, which trickles down the reeds, like gathered-up drops of water charged with music.
“Sometimes, like a mine of melody, it explodes within them and lifts them from the dark recesses of the flags into the air above.”
