Book Description
Presents results of aerial surveys undertaken to determine the principal areas used by nearctic shorebirds and other species of water birds on wintering grounds on the coast of Panama. Additional information is presented on numbers and distributions of these groups of birds on the coast of the Gulf of Panama during migration periods. Surveys of wintering populations were carried out in January 1993, while surveys of populations present during southward and northward migration periods were conducted in October 1991 and February 1988 respectively. Information is also included on aerial survey methodology; the geography, physical oceanography, and climate of Panama; and coastal habitats and their distribution in Panama.

Book Description
Heron Conservation provides a comprehensive update following two distinct threads. The status and conservation needs of herons are first presented on a regional basis, in a series of chapters set at continental or subcontinental scale. Over 200 biologists and heron conservationists - many associated with the Heron Specialist Group sponsored by Wetlands International and IUCN - have contributed to the data summarised here and these very latest census and survey results provide the most up to date and detailed picture of heron populations currently available. Chapters discussing several critical issues in heron conservation follow, often focusing on the international nature of the problem. Many heron populations are migratory and depend upon conservation of both summer and wintering wetland habitats often located on different continents. Effective conservation of these wetlands of international importance depends in large part on local and regional socio-economic factors. Herons, to the extent that they require maintenance of wetland functioning, should be an integral part of sustainable wetland conservation. Features: * Fascinating insight into a topical issue * Beautiful colour pho
