“The flock life of the roost now ends. Every Jack chooses his Jill, and mingled with the harsh warning cries of the older birds are sounds that sometimes have a suggestion that their makers are trying to sing. The funniest thing in birdland is to see a Crow or a Purple Grackle making love, standing on tiptoe on a branch, raising their wings by jerks, like pump-handles that are stiff, while the sounds they make stick in the throat in a manner that suggests Crow croup. “Once in a long time, however, I have heard a Crow begin with a high Caw, and then followed a series of soft, almost musical, notes, though without tune or finish, but this is the exception. But what, in his courting days, a Crow lacks in song, he makes up by wonderful feats of flight. For his size, the Crow is always a graceful bird on the wing. When he flaps slowly up against the wind, there is nothing laboured in his motions, but in the spring, in company with a desired mate, his swift dives into the air, wheels to right and left, circlings often finished by a series of somersaults across the sky, are really marvellous. “Now the pair of Crows that we will call Jack and Jill, to save time, leave the cedar woods and begin hunting for a nesting-site. At first they looked through the hickory woods for an old Hawk’s nest for a foundation upon which to build, but this year there were two Red-tailed Hawks already in possession, and so they hurried away as quickly as possible, for Hawks do not like Crows, and tell them so very plainly. “Next day they spied the great white pine back of Farmer Boardman’s barn. They liked the looks of the tree, for it had a bunch of closely knit branches near the top, and the neighbourhood in all respects promised good feeding, but before they had carried more than a few coarse sticks and put them in place, the farmer’s man saw them, and not only fired his gun at them to drive them away, but climbed the tree and threw the sticks away in order to be sure that they should not rest there. “What did Jack and Jill do next? They came flying over here. The place was attractive, and it was easy to slip from the pine woods to the hickories, then across to the orchard, and up to the spruce trees outside the window here. Goldilocks was too ill to come up into the playroom then, and so the windows on this side of the attic were shut. “The nest-building began in earnest, both birds working at it. First, a foundation of stout sticks, some of them being half-dead twigs from these same spruces; then, old weed stalks and vine tendrils, mixed with corn husks, until a heap was collected that would fill a half-bushel basket.
