摘要：

Experiments using artificial nests to test whether predation varies with nest density were conducted in a northern hardwood forest in New Hampshire in June 1989. Nests were baited with quail eggs and placed at densities similar to and substantially higher than the range of natural nest densities. There was no statistically significant difference in predation levels among densities, but there was a trend for higher predation at the highest density.
