On the 25th of April, before the trees were in leaf, I heard the first true wood-note of the spring. It came from the tall oaks beyond the garden. "_Clear, clear, clear up!_" it rang, pure, untamed, and quickening. The solitary vireo! It was his whistle, inimitable, unmistakable; and though I had not seen him since last July, I hurried out to the woods, sure he would greet me. Solitary is the largest, rarest, tamest, and sweetest-voiced of the vireos. I soon found him high in the tops of the trees; but I wanted him nearer. He would not descend. So I chased him, stoning and mocking him even, till, at last, he came down to the bushes and showed me his big blue head, white eye-rings, wing-bars, and yellow-washed sides. [Illustration: "It was a love-song."] He did more than show himself: he sang for me. Within ten feet of me, he began a quiet little warble of a tenderness and contentment I never heard before. Such variety of notes, such sweetness of melody, such easy, unconscious rendering! It was a love-song, but sung all to himself, for he knew that there was no gentle heart to listen this side of Virginia. He sang to his own happy heart as pure and sweet a song as the very angels know. Solitary disappeared from that day. I concluded he had gone to heavier, wilder woods to nest. It was late in June that, passing through this brush-land, I saw hanging from an oak sapling, just above my head, a soft, yellowish basket. It was a vireo's nest; but it was too large, too downy, too yellow for Red-eye. There were no bunches of white spider-webs upon it, such as Red-eye hangs all over his nest. I stepped aside for a better view, and had just caught the glint of a large, white-ringed eye peering over the nest's edge at me, when, off in the woods behind me, the noon hush was startled by Solitary's whistle--a round, pure, pearly note that broke the quiet as pearly teeth break through the smile of a beautiful face. He soon appeared, coming on, a tree at a time, looking and asking, in no hurry and in no alarm. When he reached the pine overhead, his mate left the nest to confer with him. They scolded me mildly while I climbed for a look at the four delicately spotted eggs; but as soon as I lay down upon the ground, the mother, without fuss or fear, slipped into the nest and cuddled down over the eggs till her head hardly showed above the rim. Had a few bushes been removed I could have seen the nest from my front door.
