Field Protocol to Monitor Cavity-Nesting Birds;Forest Service research station

摘要

We developed a field protocol to monitor populations of cavity-nesting birds in burned and unburned coniferous forests of western North America. Standardized field methods are described for implementing long-term monitoring strategies and for conducting field research to evaluate the effects of habitat change on cavity-nesting birds. Key references (but not methodologies) for statistical analyses and habitat measurements are listed in our protocol. The protocol includes sections on study design, creation of field maps, conducting nest surveys, locating nest cavities by search image and bird behavior, recording data, nest monitoring, and data management.
