Methods for collecting data about the breeding biology of Neotropical birds

The study of avian nesting biology in North America and Europe has a long history, resulting in an expansive and information-rich literature. In contrast, the tropics have been relatively neglected and, in most ways, we are still at the frontier of exploration. Data about basic nest descriptions and natural history information are still lacking for many Neotropical species; standardization of data collection methods is needed for comparative analyses. Hence, our goals are: (1) motivate a new generation of Neotropical naturalists to collect nesting data by providing basic tips on how to find nests and collect basic data, (2) provide guidelines on how to use and analyze basic data, (3) highlight the importance of collections, (4) describe modern monitoring techniques, and (5) suggest how these data can be used to fill important gaps concerning the breeding biology of tropical birds. Understanding avian nesting biology and the biotic and abiotic factors that influence nesting success is crucial for a better understanding of bird population dynamics and breeding strategies at the community level, and can form the basis for the development of sound conservation measures.
