あらすじ
For ten months of the year, the prairie-chicken’s drab colors allow it to disappear into the landscape. However, in April and May this grouse is one of the most outrageously flamboyant birds in North America. Competing with each other for the attention of females, males gather before dawn in an explosion of sights and sounds—“booming from the mists of nowhere,” as Aldo Leopold wrote decades ago. There’s nothing else like it, and it is perilously close to being lost. In this book, ecologist Greg Hoch shows that we can ensure that this iconic bird flourishes once again. Skillfully interweaving lyrical accounts from early settlers, hunters, and pioneer naturalists with recent scientific research on the grouse and its favored grasslands, Hoch reveals that the prairie-chicken played a key role in the American settlement of the Midwest. Many hungry pioneers regularly shot and ate the bird, as well as trapping hundreds of thousands, shipping them eastward by the trainload for coastal suppers. As a result of both hunting and habitat loss, the bird’s numbers plummeted to extinction across 90 percent of its original habitat. Iowa, whose tallgrass prairies formed the very center of the greater prairie-chicken’s range, no longer supports a native population of the bird most symbolic of prairie habitat. The steep decline in the prairie-chicken population is one of the great tragedies of twentieth-century wildlife management and agricultural practices. However, Hoch gives us reason for optimism. These birds can thrive in agriculturally productive grasslands. Careful grazing, reduced use of pesticides, well-placed wildlife corridors, planned burning, higher plant, animal, and insect diversity: these are the keys. If enough blocks of healthy grasslands are scattered over the midwestern landscape, there will be prairie-chickens—and many of their fellow creatures of the tall grasses. Farmers, ranchers, conservationists, and citizens can reverse the decline of grassland birds and insure that future generations will hear the booming of the prairie-chicken.
作品考察・見どころ
本書は、草原の消滅と共に静寂へ追いやられたソウゲンライチョウの咆哮を、科学と抒情的な筆致で蘇らせる一冊です。著者は開拓者の記録と最新の生態学を編み込み、この鳥をミッドウェストの記憶を宿す象徴として描きました。失われゆく「霧の中の求愛」を巡る考察は、読者の魂に響く挽歌であり、大地再生への熱烈な祈りでもあります。 映像版では、まさに「音と色彩の爆発」である舞が五感を震わせますが、その歴史的な重みを深く理解するにはテキストの言葉が不可欠です。映像が捉える刹那の美と、書籍が提示する重層的な知識。この双方向のシナジーこそが、失われた大草原の鼓動を、現代の私たちの心に鮮明に再構築させてくれるのです。
