Table 2. Number of individuals and species observed on two study plots.
Total number of individuals recorded during observation on two 100-ha plots (Harpia, Puma) and Tiputini Biodiversity Station. Number of days of observations are indicated for each year. Number of unidentified birds are given with percentage of total. Observed number of species is given as is the number expected based on rarefaction analysis (95% CI) of the monitor-based data using the same number of records.
