Figure 1: Vocalizations per hour at each of nine AÌga nests. Values represent percent of vocalizations during each hour, totaling 100% for each nest. As the hour bars represent the sum of percent for each site in that hour, some hours exceed 100%.

Figure 2: Peak frequency (Hz) measurements of two male and two female captive-reared AÌga at four time-points in development. While frequency generally decreases with age, males and females see the highest rate of change at different ages.
