FIG. 3.

An example of the percentage of the maximum number of files per day that contain biosonar signals for each species in the period from 20 October 2010 until 26 January 2011 at the SW location of Kauai.

FIG. 4.

(Color online) An example of the average number of files in which foraging clicks from the different species were detected on an hourly basis for the time period between 20 October 2010 and 26 January 2011 at the SW location of Kauai. The percentage of twilight-night detection is shown in the shaded block of each histogram.
