How alert and vigilant the birds are, even when absorbed in building their nests! In an open space in the woods I see a pair of cedar-birds collecting moss from the top of a dead tree. Following the direction in which they fly, I soon discover the nest placed in the fork of a small soft maple, which stands amid a thick growth of wild cherry-trees and young beeches. Carefully concealing myself beneath it, without any fear that the workmen will hit me with a chip or let fall a tool, I await the return of the busy pair. Presently I hear the well-known note, and the female sweeps down and settles unsuspectingly into the half-finished structure. Hardly have her wings rested before her eye has penetrated my screen, and with a hurried movement of alarm she darts away. In a moment the male, with a tuft of wool in his beak (for there is a sheep pasture near), joins her, and the two reconnoitre the premises from the surrounding bushes. With their beaks still loaded, they flit round with a frightened look, and refuse to approach the nest till I have moved off and lain down behind a log. Then one of them ventures to alight upon the nest, but, still suspecting all is not right, quickly darts away again. Then they both together come, and after much peeping and spying about, and apparently much anxious consultation, cautiously proceed to work. In less than half an hour it would seem that wool enough has been brought to supply the whole family, real and prospective, with socks, if needles and fingers could be found fine enough to knit it up. In less than a week the female has begun to deposit her eggs,—four of them in as many days,—white tinged with purple, with black spots on the larger end. After two weeks of incubation the young are out.
Excepting the American goldfinch, this bird builds later in the season than any other, its nest, in our northern climate, seldom being undertaken till July. As with the goldfinch, the reason is, probably, that suitable food for the young cannot be had at an earlier period.
I knew a pair of cedar-birds, one season, to build in an apple-tree, the branches of which rubbed against the house. For a day or two before the first straw was laid, I noticed the pair carefully exploring every branch of the tree, the female taking the lead, the male following her with an anxious note and look. It was evident that the wife was to have her choice this time; and, like one who thoroughly knew her mind, she was proceeding to take it. Finally the site was chosen upon a high branch, extending over one low wing of the house. Mutual congratulations and caresses followed, when both birds flew away in quest of building-material. That most freely used is a sort of cotton-bearing plant which grows in old worn-out fields. The nest is large for the size of the bird, and very soft. It is in every respect a first-class domicile.
The cedar-bird is the most silent bird we have. Our neutral-tinted birds, like him, as a rule are our finest songsters; but he has no song or call, uttering only a fine bead-like note on taking flight. This note is the cedar-berry rendered back in sound. When the ox-heart cherries, which he has only recently become acquainted with, have had time to enlarge his pipe and warm his heart, I shall expect more music from him. But in lieu of music, what a pretty compensation are those minute, almost artificial-like, plumes of orange and vermilion that tip the ends of his wing quills! Nature could not give him these and a song too.
THE GOLDFINCH
About the most noticeable bird of August in New York and New England is the yellowbird, or goldfinch. This is one of the last birds to nest, seldom hatching its eggs till late in July. It seems as if a particular kind of food were required to rear its brood, which cannot be had at an earlier date. The seed of the common thistle is apparently its mainstay. There is no prettier sight at this season than a troop of young goldfinches, led by their parents, going from thistle to thistle along the roadside and pulling the ripe heads to pieces for the seed. The plaintive call of the young is one of the characteristic August sounds. Their nests are frequently destroyed, or the eggs thrown from them, by the terrific July thunder-showers. Last season a pair had a nest on the slender branch of a maple in front of the door of the house where I was staying. The eggs were being deposited, and the happy pair had a loving conversation about them many times each day, when one afternoon a very violent storm arose which made the branches of the trees stream out like wildly disheveled hair, quite turning over those on the windward side, and emptying the pretty nest of its eggs. In such cases the birds build anew,—a delay that may bring the incubation into August.
It is a deep, snug, compact nest, with no loose ends hanging, placed in the fork of a small limb of an apple-tree, a peach-tree, or an ornamental shade-tree. The eggs are faint bluish-white.
While the female is sitting, the male feeds her regularly. She calls to him on his approach, or when she hears his voice passing by, in the most affectionate, feminine, childlike tones, the only case I know where the sitting bird makes any sound while in the act of incubation. When a rival male invades the tree, or approaches too near, the male whose nest it holds pursues and reasons or expostulates with him in the same bright, amicable, confiding tones. Indeed, most birds make use of their sweetest notes in war. The song of love is the song of battle too. The male yellowbirds flit about from point to point, apparently assuring each other of the highest sentiments of esteem and consideration, at the same time that one intimates to the other that he is carrying his joke a little too far. It has the effect of saying with mild and good-humored surprise, "Why, my dear sir, this is my territory; you surely do not mean to trespass; permit me to salute you, and to escort you over the line." Yet the intruder does not always take the hint. Occasionally the couple have a brief sparring-match in the air, and mount up and up, beak to beak, to a considerable height, but rarely do they actually come to blows.
