Still keeping among the unrecognized, the white-eyed vireo, or flycatcher, deserves particular mention.  The song of this bird is not particularly sweet and soft; on the contrary, it is a little hard and shrill, like that of the indigo-bird or oriole; but for brightness, volubility, execution, and power of imitation, he is unsurpassed by any of our northern birds.  His ordinary note is forcible and emphatic, but, as stated, not especially musical; Chick-a-re’r-chick, he seems to say, hiding himself in the low, dense undergrowth, and eluding your most vigilant search, as if playing some part in a game.  But in July of August, if you are on good terms with the sylvan deities, you may listen to a far more rare and artistic performance.  Your first impression will be that that cluster of azalea, or that clump of swamp-huckleberry, conceals three of four different songsters, each vying with the the others to lead the chorus.  Such a medley of notes, snatched from half the songsters of the field and forest, and uttered with the utmost clearness and rapidity, I am sure you cannot hear short of the haunts of the genuine mockingbird.  If not fully and accurately repeated, there are at least suggested the notes of the robin, wren, catbird, high-hole, goldfinch, and song sparrow.  The pip, pip, of the last is produced so accurately that I verily believe it would deceive the bird herself; and the whole uttered in such rapid succession that it seems as if the movement that gives the concluding note of one strain must form the first note of the next.  The effect is very rich, and, to my ear, entirely unique.  The performer is very careful not to reveal himself in the mean time; yet there is a conscious air about the strain that impresses me with the idea that my presence is understood and my attention courted.  A tone of pride and glee, and, occasionally, of bantering jocoseness, is discernible.  I believe it is only rarely, and when he is sure of his audience, that he displays his parts in this manner.  You are to look for him, not in tall trees or deep forests, but in low, dense shrubbery about wet places, where there are plenty of gnats and mosquitoes.

The winter wren is another marvelous songster, in speaking of whom it is difficult to avoid superlatives.  He is not so conscious of is powers and so ambitious of effect as the white-eyed flycatcher, yet you will not be less astonished and delighted on hearing him.  He possesses the fluency and copiousness for which the wrens are noted, and besides these qualities, and what is rarely found conjoined with them, a wild, sweet, rhythmical cadence that holds you entranced.  I shall not soon forget that perfect June day, when, loitering in a low, ancient hemlock wood, in whose cathedral aisles the coolness and freshness seems perennial, the silence was suddenly broken by a strain so rapid and gushing, and touched with such a wild, sylvan plaintiveness, that I listened in amazement.  And so shy and coy was the little minstrel, that I came twice to the woods before I was sure to whom I was listening.  In summer he is one of those birds of the deep northern forests, that, like the speckled Canada warbler and the hermit thrush, only the privileged ones hear.
