Article Abstract:
The 1991 International Piping Plover Census represents a benchmark in recovery efforts for Piping Plovers and serves as a model of international cooperation for other endangered species program. Biologists fromCanada, US, Mexico and several Carribean nations participated in the census to establish baseline population levels for the different Piping Plover sites and study additional potential breeding and wintering sites. This event provides a better assessment of the plovers' reproductive success in local populations that will help determine future population trends for the said species.

Article Abstract:
Avian surveys in the western Great Basin from 1992-1997 indicated 31 species of shorebirds from ground surveys but accurate estimates of population size could not be obtained. On the other hand, aerial surveys were able to provide accurate values for population size for some shorebirds but could not offer reliable estimates of species diversity. Therefore, ground and aerial surveys are both needed at multiple sites through a number of years over a large area.

Article Abstract:
A study of the distribution patterns of nonbreeding American Avocets in eight brackish water impoundments and two intertidal mudflats in coastal South Carolina revealed their habitat selection to be influenced more by parameters pertaining to water levels and less with salinity levels. These birds seek habitats with predictable, adequate resource levels to cope with frequent changes in environmental conditions.
