Individual acoustic measurements of attention-getting calls, or “snough", for each female.

Listed are the following: duration of single element; duration of silent interval between calls (number of intervals considered) when given in bouts; mean frequency 1st dfa (distribution of frequency amplitude) (Q1mean); mean frequency 2nd dfa (Q2mean); Minimum difference between 1st and 2nd df (dominant frequency bands) (Diffmin); and Maximum peak frequency (Pfmax).
