Standing upon a ladder I counted eight eggs as my eyes became gradually accustomed to the partial darkness within the nest; the dark, vinaceous spots laid on so thickly as to conceal or obliterate the original color, thus helping to hide them more securely. In the long brooding days, when Jenny’s little answering heart is preoccupied and silent, the hours are sometimes long and lonely to her mate. At these times he has been known to devote his spare moments to building a nest simply for his own pleasure. Many instances of this remarkable habit are recorded of the English wren, the explanation offered being that the odd nests are for the purpose of deceiving the parasitical cuckoo.
There is also a supposition that the bird’s active nature finds relief in work, being urged on by the increasing lonesomeness. This wren-trait reaches a climax in the marsh wrens, with whom the building habit becomes a passion.
Nor is it restricted to the wren family, many instances being recorded where other species have beguiled the waiting days by an imitative housekeeping.
The house phoebe has been known to build a second nest while its mate was brooding. To all appearances this was an instance of over-developed domestic tastes. Nor did the experiment end with the completion of the duplicate nest upon which the male bird sat regularly for several hours daily.
Wrens do not take kindly to double houses, their warlike nature seeming to revolt against living friendly with near neighbors. A pair of wrens that was well established in an unoccupied martin house made it very uncomfortable for the later arrivals. While the martins were abroad after material for the nest the wrens sallied forth in an utterly vindictive spirit and scratched out all their neighbors had constructed. After singing a triumphant song with much parade they wisely retired to their own domicile to be on the defensive.
Wiser wrens, with an instinctive knowledge that an ounce of prevention is worth a pound of cure, are known to have the forethought when the box in which they build contains two compartments, to fill up one of them, thus avoiding the risk of troublesome neighbors. Wrens have been known to nest in a human skull. Others with less questionable taste, have gone to housekeeping in an old boot, a watering pot, a coat sleeve; in gourds and baskets, jars and water pipes, while another pair made a nest in the lower part of a stone vase in the garden. There was a hole for drainage in the bottom of the vase, and through this hole they found, beneath some shavings, a circular space just suited for a nest. The vase was not filled with plants until the domestic affairs of the wren family were happily concluded.
The delicate swaying hammock of the oriole is sometimes used for a second nesting.
There was bitter disappointment in wren circles earlier in the season when, with the presumption of inexperience, the pump was filled regularly with coarse twigs, which were promptly dislodged at nightfall. Undiscouraged at this defeat, the morning hours were utilized for rebuilding with a persistency well worthy a more intelligent effort; they worked and sang, sang and worked, until a cigar box was nailed to a tree for their special accommodation. This was nearly full of twigs when they decided that the building-site was ineligible, a decision hastened by the fact that just at this opportune time a glass fruit can was left upon the piazza shelf. No sooner was this glass house seen than its possibilities were realized and plans were quickly made for a kind of crystal palace experiment. Under other circumstances this might have been a dangerous precedent, as certain unneighborly conduct toward their little brothers of the air had at various times fairly invited the throwing of stones. The can was half full of tiny fagots, and Jenny was thinking of settling upon the mattress of wood fibre when the thrifty housewife turned them adrift summarily, well aware that this kind of housekeeping, within easy range of neighboring cats, would not be successful. Before such supreme content, who could have the heart to undeceive them? And yet, the can was turned upside down before they could be made to understand the situation. Like Thoreau, they did not wish to practice self-denial unless it was quite necessary!
After the failure of this crystal scheme, it was a difficult matter for Jenny to make up her mind as to a further preference, but when she really decided it was with such entire good faith as left no doubt in her lover’s mind as to her judgment. This was more flattering as it was his own choice, their last year’s home thoroughly remodeled, to which he had repeatedly called her attention, vainly. So the hole in the house jet at least answered the question, “Where are the birds in last year’s nests?” for the wrens moved in regularly, the tenor having a perch upon a projecting bracket where Jenny joined him, a regular little termagant, scolding with all her might whenever the kittens looked that way.
Marsh wrens, small brown birds, with barred wings and tail, breed in or about the swamps and marshes of Lake Champlain.
