birds in North America John James Audubon "I dismounted, seated myself on an eminence, and began to mark with my pencil, making a dot for every flock that passed. In a short time finding the task which I had, undertaken impracticable, as the birds poured in in countless multitudes , I rose, and counting the dots then put down, found that 163 had been made in twenty-one minutes. I traveled on, and still met more the farther I proceeded. The air was literally filled with Pigeons ; the light of noon-day was obscured as by an eclipse, the dung fell in spots, not unlike melting flakes of snow ; and the continued buzz of wings had a tendency to lull my senses to repose.". ..Before sunset I reached Louisville, distance from Hardensburgh fifty- five miles. The Pigeons were still passing in undiminished numbers, and continued to do so for three days in succession.”
