Requested Corrections in Tables

In the original publication [1], there was a mistake in Table 2 as published. We have detected an error in the values in column 5 of Table 2, and a column with FN values for scenario A (FN(A)) is missing. This correction affects two columns (FPR and MCC) in Tables 3 and 4 as published.
Additionally, we have added an explicit mention of FN(A) and FN(B), as well as a new Figure 4, in Section 3.4, “BirdNET Performance Assessment,” to aid readers’ understanding.
The corrected Table 2, Table 3 and Table 4 appear below.

True positives (TP) and true negatives (TN) are the BirdNETS’s correct predictions in our case study, while false negatives (FN) and false positives (FP) are the incorrect predictions.
