MIGRATING BIRDS IN DANGER:
Since Europeans first settled in the Americas, more than half of the Western hemisphere's wetlands have been destroyed. Today, in spite of regulations, wetland destruction continues.
More than 40 North American shorebird species —such as sandpipers, plovers, and curlews—breed in the Arctic and migrate to wintering sites in Central and South America. To complete these longdistance flights, shorebirds must accumulate large fuel reserves. The birds prepare for their journeys at a few food-rich staging areas, which are usually wetlands. In some cases, between 50 and 80 percent of the entire population of a species may visit a single site. The loss of such a staging area could devastate a population of shorebirds.
Studies show that the numbers of shorebirds are declining worldwide. In order to preserve and protect these valuable species, researchers must first determine shorebird populations and map their migratory routes.
Today, the work of preserving shorebirds has been greatly advanced through the use of computer technology. One group that uses computers in this work is the International Shorebird Survey (ISS). The ISS was established in 1974 and consists of both volunteers and professional researchers. The volunteers record information on populations, habitat characteristics, weather conditions, and human activity. Researchers use computer programs to identify relationships among these variables. Complex methods of analysis have revealed much about the migratory habits of shorebirds—
