Data from: Acoustic indices estimate breeding bird species richness with daily and seasonally variable effectiveness in lowland temperate Białowieża forest

The S1Dataset.xlsx file contains: Recording points distribution: ID of recording points, coordinates of each recording point, altitude, date of recording (one morning at each point during early and late survey); List of detected bird species: list of bird species detected during the study; 1-min sound sample: recording point ID, 1-min sound sample corresponding to wav file name, survey (early or late), minute in survey (Ordinal variable describing the order of 1-min sound sample at point during a day), number of bird species detected in 1-min sound sample by manual spectrogram scanning and listening to recordings, values of Bioacoustic Index (BI), Acoustic Complexity Index (ACI) and Acoustic Diversity Index (ADI) calculated for each 1-min sound sample; Survey: recording point ID, survey (early or late), total number of bird species detected manually during single survey at recording point, average number of bird species detected manually during survey at recording point (sum of bird species detected in each 1-min sound sample divided by the number of 1-min sound samples analysed during single survey equal 36); mean BI, ACI, ADI for a single survey (average values for 36 1-min sound samples analysed during single survey per recording point); Recording point: recording point ID, total number of bird species detected manually during early and late survey at recording point, average number of bird species detected manually during early and late survey at recording point (sum of bird species detected in each 1-min sound sample divided by the number of 1-min sound samples analysed during early and late survey equal 72); mean BI, ACI, ADI for for recording point (average values for 72 1-min sound samples analysed during early and late survey at recording point).
