O beautiful world of green! When bluebirds carol clear, And rills outleap, And new buds peep, And the soft sky seems more near; With billowy green and leaves,—what then? How soon we greet the red again! G. Cooper, “Round the Year.” THE WINTER WREN. (_Troglodytes hiemalis._) How rich the varied choir! The unquiet finch Calls from the distant hollows, and the wren Uttereth her sweet and mellow plaint at times. —Isaac McLellan, “The Notes of the Birds.” The Winter Wren inhabits that part of North America east of the Rocky Mountains, breeding chiefly north of the United States and migrating at the approach of winter nearly or quite to the Gulf of Mexico. This diminutive form of bird life, which is also called Bunty Wren and Little Log Wren, is a denizen of the forest, and it is more common in those forests found on bottom lands adjacent to rivers. It is a shy bird, and does not seek the intimacy of man as will its cousin, the house wren. It is seldom seen far above the ground. In many places where it does not seem abundant it may be quite common, for it readily eludes observation in the underbrush because of its neutral color. It frequents old logs, where it may be seen “hopping nimbly in and out among the knotholes and other hollow places, then flitting like a brown butterfly to another place of refuge on the too near approach of an intruder.” Some one has said, “Its actions are almost as much like that of a mouse as of a bird, rarely using its wings except for a short flutter from one bush or stone-heap to another; it creeps slyly and rapidly about, appearing for an instant and is then suddenly lost to view.” The Winter Wren builds its nest in the matted roots of an overturned tree, in brush-heaps, in moss-covered stumps, or on the side of a tree trunk. It may be attached to a ledge of rock, and is occasionally found in some unoccupied building, especially if it be a log hut in the woods. The nest is very large and bulky when compared with the size of the bird. Dr. Minot describes a nest that he found in a moss-covered stump in a dark, swampy forest filled with tangled piles of fallen trees and branches. This nest was made of small twigs and moss. It had a very narrow entrance on one side, which was covered by an overhanging bit of moss, which the bird pushed aside on entering. The nests are usually more or less globular and thickly lined with feathers and hair.
