Popis: | The use of autonomous recording units for the monitoring of birds has increased over the years. However, the time needed to listen to the recordings still remains a strong limitation, particularly for highly diverse communities. We aimed to optimize listening effort of trained observers by identifying the periods with the highest species detection rates over 720 1-min files (6 min/h). We detected 90 species within the 720 min. We managed to detect 90% (81) of the species by listening to the top 20% of highly informational minutes (a total of 150 min), a satisfactory result if the goal is to compare communities. |
