Table 5. Differences in frequency of occurrence for simultaneous-collection and same-season strategies.
Results from two-tailed significance tests (paired t-test) to evaluate mean differences in frequency of occurrence of birds from two orders identified with point count and ARU methods. Comparisons were made separately for each assessment strategy. Significant relationships are indicated in bold.
