Bird diversity survey methods
The chapter focuses on the design and methods of bird survey programmes. It deals with issues such as survey design and selection of study areas, effect of time of day and time of year on counts, how to find and count different kinds of birds, standardizing census efforts in time and space, and problems of bird detectability and survey comparability in different habitats. Mapping or ‘atlas’ methodology, based on grid cells, is also discussed, as well as methods of estimating species richness and diversity, and the storage and accessibility of data. The key points in designing bird surveys are listed. No survey method is perfect; the method chosen should be suited to both purpose and resources, in terms of money, manpower, and skill levels.
Keywords: count, census, mapping, atlas project, species richness, species diversity
