The living bird : 100 years of listening to nature
“All over the world, birds have the universal power to connect us with nature in ways that no other organism can. We love them, we want to live with them, and-perhaps most important is today’s changing world-we cannot bear the idea of living without them.
But it is bird’s ability to help us gauge the state of the natural world that takes our simple wonder to another level. Birds can tell us how well-or how poorly-we have managed the world in which we live. Because many birds are closely adapted to the conditions of specific habitats, their populations can serve as “barometers” for the condition of their landscape. Like the canary in the coal mine, birds give us early warning signals when habitats become degraded.”
