a. Top panel shows a diagram of the playback setting used for the multi-neighbor male test. Bottom panel shows the stimulus used in our tests: a) Call alternation, b) complete call overlap, c) long calls, d) call jamming, and e) endurance rivalry. Overlapped calls have complete pulse interdigitation not shown in diagram. b. Oscillogram of a male interdigitating an overlapped call with a playback. A clear call (top panel) is interrupted on the 11th pulse by a 13 pulse long playback (bottom panel). As a result, the focal male extends the length of the interpulse interval of its call avoiding interference from the playback and produces a longer call of 24 pulses. Note how the interpulse interval increases as the call progresses, lowering pulse rate. The first four intervals, (before call overlap) are about 60 ms long, the last five (during call overlap) are about 110 ms. Playback is about 2 s in duration.
