Recent shorebird trend analyses indicate that many North American shorebird species are declining, but we do not know why. Many of these species breed in the Arctic and winter in Central and South America, so their conservation needs span the entire Western Hemisphere. The goal of the Arctic Shorebird Demographics Network (Network) is to conduct demographic analyses for several target species that will help determine the factors limiting their populations. The Network will measure demographic rates like adult survival and productivity, and other demographic parameters at various life history stages. In addition, this internationally coordinated effort will substantially increase our ability to address a wide variety of other science and conservation goals that can only be approached at a regional or global level, such as migratory connectivity studies that require work across the entire range of a species.
