Abstract
When I first began to notice changes in the numbers and bird species that I netted on the Great Lakes' islands in the 1970s, I had little comprehension of the extent to which global modifications already underway were driving the changes in bird populations. With this compendium based on a symposium hosted by Manomet Bird Observatory in December, 1989, ornithologists can now substantiate the validity and seriousness of such earlier observations. The erosion of Neotropical bird populations is only one of many symptoms of planetary deterioration.
