Description of the data and file structure

One file with two sheets: datasets_final_Dryad_submit_2025-10-17.xlsx

Sheet "Dataset_GLM" - This dataset is structured with multiple variables describing nest-specific conditions with female and male song activity patterns. Each row represents a single nest observation period with the following variables:​

locality: Geographic location where the nest was monitored (Slovakia or Czechia)​

day: Day of observation, where 1 = May 1st​

female_status: Nesting status of the female (monogamous, secondary, or primary)​

male_song_activity: Scale from 0-3 indicating male singing frequency near the nest (0 = no singing, 1 = rare singing, 2 = irregular singing, 3 = regular singing)​

female_song: Binary indicator for song detection specifically in female (0 = no song, 1 = song detected)​

female_sounds_per_2h: Total count of all songs produced by female during the 2-hour recording period

Sheet "Dataset_song" - This dataset contains detailed acoustic measurements of individual song characteristics. Each row represents a single song recording with the following variables:​​

nest_ID: Unique nest identifier​

locality: Geographic location (Slovakia or Czechia)​

sex: Sex of the singing individual (female or male)​

song_length_total: Total song duration in seconds, measured from the start of the first element to the end of the last element​

song_length_without_intro: Duration in seconds of the introductory portion, measured from the start until the first non-introductory element (all elements before g1 syllable are considered introductory)​​

elements_count_total: Total number of syllable elements in the song​

elements_rate: Rate of syllable production per second​

prop_rattle: Proportion of rattle-type elements, excluding the introductory section​

prop_whistle: Proportion of whistle-type elements, excluding the introductory section​

elements_count_rattle/whistle: Total count of rattle or whistle syllables present in a song​

freq_rattle_mean/median: Mean and median peak frequency (Hz) of rattle elements, calculated from the first 10 rattle elements detected in the song​

freq_whistle_mean/median: Mean and median peak frequency (Hz) of whistle elements, calculated from the first 10 whistle elements detected in the song​

freq_rattle_sd/freq_whistle_sd: Standard deviation of peak frequency (Hz) for rattle and whistle elements, computed from the first 10 corresponding elements​​​
