The eggs of the Wren, usually from seven to nine in number, are of a rounded-oval shape, at times nearly as broad as long. Their ground-color is white, but they are so thickly studded with markings and fine spots of reddish-brown, with a few occasional points of purplish-slate, as to conceal their ground. Their shape varies from nearly spherical to an oblong-oval, some measuring .60 by .55 of an inch, others with the same breadth having a length of .67 of an inch. Under the name of _Troglodytes americanus_, or Wood Wren, Mr. Audubon figured and described as a distinct species what is probably only a somewhat larger and darker form of the present species, hardly distinct enough to be treated even as a race. Mr. Audubon met with an individual near Eastport in 1832. The young were following their parents through the tangled recesses of a dark forest, in search of food. Others were obtained in the same part of Maine, near Dennisville, where Mr. Lincoln informed Mr. Audubon that this bird was the common Wren of the neighborhood, and that they bred in hollow logs in the woods, but seldom approached farm-houses. In the winter following, at Charleston, S. C., Mr. Audubon again met individuals of this supposed species, showing the same habits as in Maine, remaining in thick hedges, along ditches in the woods, not far from plantations. The notes are described as differing considerably from those of the House Wren. It has not been seen by Mr. Boardman, though residing in the region where it is said to be the common Wren. Professor Verrill mentions it as a rare bird in Western Maine. Mr. Charles S. Paine, of Randolph, Vt., is the only naturalist who has met with what he supposes were its nest and eggs. The following is his account, communicated by letter. “The Wood Wren comes among us in the spring about the 10th or 15th of April, and sings habitually as it skips among the brush and logs and under the roots and stumps of trees. In one instance I have known it to make its appearance in midwinter, and to be about the house and barn some time. It is only occasionally that they spend the summer here (Central Vermont). The nest from which I obtained the egg you now have, I found about the first of July, just as the young were about to fly. There were five young birds and one egg. The nest was built on the hanging bark of a decaying beech-log, close under the log. A great quantity of moss and rotten wood had been collected and filled in around the nest, and a little round hole left for the entrance. The nest was lined with a soft, downy substance. I have no doubt that they sometimes commence to breed as early as the middle of May, as I have seen their young out in early June.”
