For his cousin, the catbird, I have a still warmer regard. Always a good singer, he sometimes nearly equals the brown thrush, and has the merit of keeping up his music later in the evening than any bird of my familiar acquaintance. Ever since I can remember, a pair of them have built in a gigantic syringa near our front door, and I have known the male to sing almost uninterruptedly during the evenings of early summer till twilight duskened into dark. They differ greatly in vocal talent, but all have a delightful way of crooning over, and, as it were, rehearsing their song in an undertone, which makes their nearness always unobtrusive. Though there is the most trustworthy witness to the imitative propensity of this bird, I have only once, during an intimacy of more than forty years, heard him indulge it. In that case, the imitation was by no means so close as to deceive, but a free reproduction of the notes of some other birds, especially of the oriole, as a kind of variation in his own song. The catbird is as shy as the robin is vulgarly familiar. Only when his nest or his fledglings are approached does he become noisy and almost aggressive. I have known him to station his young in a thick cornel-bush on the edge of the raspberry-bed, after the fruit began to ripen, and feed them there for a week or more. In such cases he shows none of that conscious guilt which makes the robin contemptible. On the contrary, he will maintain his post in the thicket, and sharply scold the intruder who ventures to steal _his_ berries. After all, his claim is only for tithes, while the robin will bag your entire crop if he get a chance. Dr. Watts's statement that "birds in their little nests agree," like too many others intended to form the infant mind, is very far from being true. On the contrary, the most peaceful relation of the different species to each other is that of armed neutrality. They are very jealous of neighbors. A few years ago I was much interested in the housebuilding of a pair of summer yellow-birds. They had chosen a very pretty site near the top of a tall white lilac, within easy eye-shot of a chamber window. A very pleasant thing it was to see their little home growing with mutual help, to watch their industrious skill interrupted only by little flirts and snatches of endearment, frugally cut short by the common-sense of the tiny house-wife. They had brought their work nearly to an end, and had already begun to line it with fern-down, the gathering of which demanded more distant journeys and longer absences. But, alas! the syringa, immemorial manor of the catbirds, was not more than twenty feet away, and these "giddy neighbors" had, as it appeared, been all along jealously watchful, though silent, witnesses of what they deemed an intrusion of squatters. No sooner were the pretty mates fairly gone for a new load of lining, than "To their unguarded nest these weasel Scots Came stealing."(1)
