Produktbeschreibung
Excerpt from A Popular Handbook of the Ornithology of the United States and Canada, Vol. 2: Based on Nuttall´s Manual To the west it is found to the base of the Northern Andes, or Rocky Mountains, but does not appear to be known beyond this natural barrier to its devious wanderings. As might be supposed from its extraordinary history, it is formed with peculiar strength of wing, moving through the air with extreme rapidity, urging its flight also by quick and very muscular strokes. During the season of amorous address it often flies out in numerous hovering circles; and while thus engaged, the tips of the great wing-feathers are heard to strike against each other so as to produce a very audible sound. The almost incredible and unparalleled associations which the species form with each other appear to have no relation with the usual, motives to migration among other birds. A general and mutual attachment seems to occasion this congregating propensity. Nearly the whole species, which at any one time inhabit the continent, are found together in the same place; they do not fly from climate, as they are capable of enduring its severity and extremes. They are even found to breed in the latitude of 51 degrees, round Hudson Bay and the interior of New Hampshire, as well as in the 32d degree in the dense forests of the great valley of the Mississippi. The accidental situation of their food alone directs all their movements; while this continues to be supplied they sometimes remain sedentary in a particular district, as in the dense forests of Kentucky, where the great body remained for years in succession, and were scarcely elsewhere to be found; and here, at length, when the mast happened to fail, they disappeared for several years. The rapidity of flight, so necessary in their vast domestic movements, is sufficiently remarkable. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
