Fig. 4. (A) Timing of one female's reply (animal no. 50) from the start of the male call (zero). As the female increases the number of clicks the entire reply remains within a distinct window between 800-1800 ms. The symbols and associated legend indicate the timing of the first (diamond) to eighth click (horizontal mark) of each set of clicks while the horizontal line indicates the end of part C of the male call. (B) Timing of the first and last clicks of seven females from the start of the male call; the open circles without error bars represent data from one female only. The end of part C of the male call is shown as a solid horizontal line while the end of part B is a broken line. Values are means ± S.D.
