Table 3 in A new species of scops-owl (Aves, Strigiformes, Strigidae, Otus) from Principe Island (Gulf of Guinea, Africa) and novel insights into the systematic affinities within Otus

Table 3. Measurements (in Hz) of bioacoustic variables (temporal parameters) of Otus species of the Afro-Palearctic clade, O. brucei and of O. ireneae (the species whose vocalisations are closest to the ones of the candidate species from Príncipe). n: number of individuals. Average ± standard deviation; (minimum-maximum values). DT1: total duration; DT2: time to maximum amplitude; DT3: time to maximum frequency; DT4: internote interval; DF1: frequency drop from start to end; DF2: frequency range; DFT1: slope from 25% to 75% of total duration; DFT2: slope from midpoint to end.
