So the bobolink who swung so conspicuously on the meadow grass in June in his black and white suit comes through the moulting season brown as a sparrow. The vivid blue of the indigo bunting falls from him in patches and is replaced by grayish brown in a large measure. No wonder that, utterly tired out and their brilliant plumage scattered and changed to dull and rusty colors, the birds are silent for a time, waiting for strength to recuperate. Some of them seem to retain enough courage and vitality to sing mornings through the moulting season, notably the robins. I suspect, though, that these faithful few--for the robin singers of the morning of the first day of August will be as one to twenty to those of the first day of June--are gay young sports who did not care to marry, or who, disappointed in love, still sing to keep their courage up. It is the best singers who are most strangely silent now, as they have been for weeks; nor will most of them be heard until next spring, hereabouts. My catbird was so sorrowfully unseen and unheard that I began to think the cat had got him, till I hunted him up, down the hill among the scrub oaks. He was as dilapidated and passé-looking as his nest in the lilacs; as if, like it, the young birds had kicked him pretty nearly to pieces before they got through with him. But he perked up a bit when he saw me, flipped an apology for a tail, and miaued in a manner that was humorously unlike him, it was so deprecatory. But that was a week or ten days ago. Yesterday I heard some bird cooing a little song to himself out in the arbor-vitæ trees at the foot of the garden, and slipping quietly up found that it was the catbird again. He was quite sleek in his new coat, and he was practising his song in a delightful undertone, as if to be sure that he should not forget it altogether. In four or five weeks more he will begin to flip saucily across the miles of country that separate him from his winter home in Southern Florida, or perhaps farther yet in some stretch of primeval forest that I myself have seen and loved in the heart of Santo Domingo. He will not sing his song there, high on some giant ceiba or swinging on the plume of some royal palm. He may not sing it again here on the tip of the tallest white lilac bush, but I know that, there or here, he will practise it now and then in that soft, sweet undertone which you would not believe of a catbird, and be ready to send it forth in jubilant peals when his strong wings bring him back again next May. My bluebirds may winter with him; and if they do I have hopes that he may persuade them to try my pear-tree box once more next spring. THE POND AT LOW TIDE THE POND AT LOW TIDE
