Receiver bias and the acoustic ecology of aye-ayes (Daubentonia madagascariensis)

Figures & data

Figure 1. (A) Adult aye-aye and spectrogram of percussive foraging behavior. Each tap of the third digit is discernable with a dominant energy of 6–15 kHz. (B) Mean audiogram of two aye-ayes and the region of best auditory sensitivity (modified from Ramsier et al.²¹). Insert: spectrogram of the aye-aye’s primary long-distance vocalization, the screech (‘aack’ variant), with a dominant frequency of 2.66 kHz (modified from Figure 1J in Stanger and Macedonia³⁰).
