In many parts of Europe storks build their nests on the roofs. Swallows, martins, sparrows and wrens often make their nests under our roofs. They confide in us, and trust in our friendship and care. Let us never, my boys, betray or abuse their confidence.
There is a kind of birds who travel all over the United States. They go from South to North, from North to South. They have not, like the martins, the bob-o'-links, and some others, regular times for going and coming; but travel more to obtain food than to escape the winter, and, when once settled in a place with enough suitable food and water, remain there till it is exhausted, and then take flight to some other place.
"Are you telling us a made-up story, Mother?" said Harry.
"No, Harry, it is really and truly the wild pigeon of America of which I am speaking. Indeed, if it were not for their great power of flight, they must, many of them, starve to death. A proof of their swiftness is the fact that a pigeon has been killed in the neighborhood of New York, with rice in his crop that he must have swallowed in the fields of Georgia or Carolina."
"How could any one know that?" asked Harry.
"By remembering the fact that in one of those states is the nearest spot at which the bird could have found rice growing. It is a well ascertained fact that their power of digestion is so great, that their food is in the course of twelve hours so entirely changed, that one cannot know what it was. Now the distance of the rice fields from New York—that is, the number of miles travelled in twelve hours—is such that the pigeon must have flown at the rate of about a mile in a minute; so that if he pleased he might go to England in two days; but, Frank, if you will give me that pamphlet that lies on the table, I will read the account of the wild pigeon of America from the book itself."
"It was written by the celebrated Audubon, who resided a great many years in America, and who most faithfully watched the birds he described."
After giving an account of the speed of the pigeon, he goes on to say, "This great power of flight is seconded by as great a power of vision, which enables them, as they travel at that great rate, to view objects below, and so discover their food with facility. This I have proved to be the case by observing the pigeons, as they were passing over a barren part of the country, keep high in the air, and present such an extensive front as to enable them to observe hundreds of acres at once."
"If, on the contrary, the land is richly covered with food, or the trees with mast, (the fruit of the oak and beech trees,) the birds fly low, in order to discover the portion of woods most plentifully supplied, and there they alight. The form of body of these swift travellers is an elongated (lengthened) oval steered by a long, well-plumed tail,"—just as you know, Harry, you steer your boat by the rudder in the great tub of water; "they are furnished with extremely well set muscular wings. If a single bird is seen gliding through the woods and close by, it passes apparently like a thought, and the eye, on trying to see it again, searches in vain—the bird is gone."
The multitudes of pigeons in our woods are astonishing; and, indeed, after having for years viewed them so often, under so many circumstances, and I may add in many different climates, I even now feel inclined to pause and assure myself that what I am going to relate is fact.
