The bearing of the mother of the pine-tree brood was somewhat different from that of her mate, and by their manners only could the pair be distinguished. Whatever may be Nature's reason for dressing the sexes unlike each other in the feathered world,—which I will leave for the wise heads to settle,—it is certainly an immense advantage to the looker-on in birddom. When a pair are facsimiles of each other, as are the jays, it requires the closest observation to tell them apart; indeed, unless there is some defect in plumage, which is not uncommon, it is necessary to penetrate their personal characteristics, to become familiar with their idiosyncrasies of habit and manner. In the pine-tree family, the mother had neither the presence of mind nor the bluster of the partner of her joys. When I came too near the nest tree, she greeted me with a plaintive cry, a sort of "craw! craw!" at the same time "jouncing" herself violently, thus protesting against my intrusion; while he saluted me with squawks that made the welkin ring. Neither of them paid any attention to me, so long as I remained upon a stationary bench not far from their tree; they were used to seeing people in that place, and did not mind them. It was the unexpected that they resented. Having established our habits, birds in general insist that we shall govern ourselves by them, and not depart from our accustomed orbit.
On near acquaintance, I found the jay possessed of a vocabulary more copious than that of any other bird I know, though the flicker does not lack variety of expression. When some aspiring scientist is ready to study the language of birds, I advise him to experiment with the blue jay. He is exceedingly voluble, always ready to talk, and not in the least backward in exhibiting his accomplishments. The low-toned, plaintive sounding conversation of the jays with each other, not only beside the nest, but when flying together or apart, or in brief interviews in the lilac bush, pleased me especially, because it was exactly the same prattle that a pet blue jay was accustomed to address to me; and it confirmed what I had always believed from his manner, that it was his most loving and intimate expression, the tone in which he addresses his best beloved.
Beside the well-known squawk, which Thoreau aptly calls "the brazen trump of the impatient jay," the shouts and calls and war-cries of the bird can hardly be numbered, and I have no doubt each has its definite meaning. More rarely may be heard a clear and musical two-note cry, sounding like "ke-lo! ke-lo!" This seems to be something special in the jay language, for not only is it peculiar and quite unlike every other utterance, but I never saw the bird when he delivered it, and I was long in tracing it home to him. Aside from the cries of war and victory, jays have a great variety of notes of distress; they can put more anguish and despair into their tones than any other living creature of my acquaintance. Some, indeed, are so moving that the sympathetic hearer is sure that, at the very least, the mother's offspring are being murdered before her eyes; and on rushing out, prepared to risk his life in their defense, he finds, perhaps, that a child has strayed near the tree, or something equally dreadful has occurred. Jays have no idea of relative values; they could not make more ado over a heart-breaking calamity than they do over a slight annoyance. Some of their cries, notably that of the jay baby, sound like the wail of a human infant. As to one curious utterance in the jay répertoire, I could not quite make up my mind whether it was a real call to arms, or intended as a joke on the neighborhood. When a bird, without visible provocation, suddenly burst out with this loud two-note call, instantly every feathered individual was on the alert,—sprang to arms, as it were. Blue jays joined in, robins hurried to the tops of the tallest trees and added their excited notes, with jerking wings and tail, and at the second or third repetition the whole party precipitated itself as one bird—upon what? Nothing that I could discover.

STORY OF THE NESTLINGS.
While I was studying the manners and customs of the bird in blue, babies were growing up in the pine-tree nest. Five days after I began to observe, I saw little heads above the edge. On the sixth day they began, as mothers say, to "take notice," stirring about in a lively way, clambering up into sight, and fluttering their draperies over the edge. Now came busy and hungry times in the jay family; the mother added her forces, and both parents worked industriously from morning till night.
On the seventh day I was up early, as usual, and, also as usual, my first act was to admire the view from my window. I fancied it was the most beautiful in the early morning, when the sun, behind the rampart of locust and other trees, threw the yard into deep shade, painting a thousand shadow pictures on the grass; but at still noon, when every perfect tree stood on its own shadow, openings looked dark and mysterious, and a bird was lost in the depths, then I was sure it was never so lovely; again at night, when wrapped in darkness, and all silent except the subdued whisper of the pine, with its
