Fig. 10. Inter-fish distance centred at the time of signal production for (A) Type 2
chirps (N=25) and (B) AFRs (N=39). The inter-fish distances
represent the distance from one fish's snout to the other fish's snout. Means
± s.e.m. are plotted for males only in the case of Type 2 chirps, and
all fish in the case of AFRs.
