Shall we go, then, to Kentucky? For 'twas there the man named Audubon once saw them come in flocks to roost at night. They kept coming from sunset till after midnight, and their numbers were so great that their wings, even while still a long way off, made a sound like a gale of wind; and when close to, the noise of the birds was so loud that men could not hear one another speak, even though they stood near and shouted. The place where Audubon saw these pigeons was in a forest near the Green River; and there were so many that they filled the trees over a space forty miles long and more than three miles wide. They perched so thickly that the branches of the great trees broke under their weight, and went crashing to the ground; and their roosting-place looked as if a tornado had rushed through the forest.
Must there not be wild pigeons, yet, roosting in Kentucky—some small flock, perhaps, descended from the countless thousands seen by Audubon? No, not one of all these doves is left, they tell us, in the woods in that part of the country. The rush of their wings has been stilled and their evening uproar has been silenced. Men may now walk beside the Green River, and hear each other though they speak in whispers.
Would you like to seek the dove in Michigan in May? For there it was, and then it was, that these wild pigeons nested, so we are told by people who saw them, by hundreds of thousands, or even millions. They built in trees of every sort, and sometimes as many as one hundred nests were made in a single tree. Almost every tree on one hundred thousand acres would have at least one nest. The lowest ones were so near the ground that a man could reach them with his hand.
Suppose you should find just one pair.
Suppose you should find, next May, just one pair nesting. Sire Dove, we think from what we have read, would help bring some twigs, and Dame Dove would lay them together in a criss-cross way, so that they would make a floor of sticks, sagging just a little in the middle. As soon as the floor of twigs was firm enough, so that an egg would not drop through, Dame Dove would put one in the shallow sagging place in the middle. It would be a white egg, very much like those our tame pigeons lay; and, because there would be no thick soft warm rug of dried grass on the floor, you could probably see it right through the nest, if you should stand underneath and look up. But you couldn't see it long, because, almost as soon as it was laid, Dame Dove would tuck the feather comforter she carried on her breast so cosily about that precious egg, that it would need no other padding to keep it warm. She would stay there, the faithful mother, from about two o'clock each afternoon until nine or ten o'clock the next morning. She would not leave for one minute, to eat or get a drink of water. Then, about nine or ten o'clock each morning, Sire Dove would slip onto the nest just as she moved off, and they would make the change so quickly that the egg could not even get cool. That one very dear egg would need two birds to take care of it, one always snuggling it close while the other ate and flew about and drank.
So they would sit, turn and turn about, for fourteen days. All this while they would be very gentle with each other, saying softly, "Coo-coo," something as tame pigeons do, only in shorter notes, or calling, "Kee-kee-kee." And sometimes Sire Dove would put his beak to that of his nesting mate and feed her, very likely, as later they would feed their young. For when the two weeks' brooding should be over, there would be a funny, homely, sprawling, soft and wobbly baby dove within the nest.
The father and mother of him would still have much to do, it seems; for hatching a dove out of an egg is only the easier half of the task. The wobbly baby must be brought up to become a dove of grace and beauty. That would take food.
But you must not think to see Sire and Dame Dove come flying home with seeds or nuts or fruit or grain or earthworms or insects in their beaks. What else, then, could they bring? Well, nothing at all, indeed, in their beaks; for the food of a baby dove requires especial preparation. It has to be provided for him in the crop of his parent. So Dame Dove would come with empty beak but full crop, and the baby would be fed. Just exactly how, I have not seen written by those people who saw a million Passenger Pigeons. Perhaps they did not stop to notice.
