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.

Figure 4. Graphical explanation for assessing BirdNET predictions from audio files, for calculating the following performance metrics. FN has different values in Scenario A (FN(A)) and Scenario B (FN(B)).

The corrected Table 2, Table 3 and Table 4 appear below.

Table 2. Results of the confusion matrix for the different combinations of Overlap and Sensitivity.

Table 3. Performance table referring to the 80 species of birds inventoried in the study area.

Table 4. Performance table referring to the 68 bird species identified through audio recordings out of the 80 species inventoried in the study area.

The authors would like to apologize for any inconvenience caused to the readers by these changes. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.
