The objectives of this study were: (1) to compile a comprehensive species inventory of at least 90% of all breeding, transient, and migratory bird species that, under normal circumstances, occur within the management units of interest; (2) to provide relative abundance measures for each of the documented species; and (3) to provide the baseline information needed to develop a general monitoring strategy and design that can be implemented by the park once inventories have been completed, tailored to specific park threats and resource issues.
