... insect approach sequences are clusters of sonar sounds, termed sonar sound groups (SSGs). The bat's production of SSGs has been observed in both field and laboratory conditions, and is hypothesized to sharpen spatiotemporal sonar resolution. When insectivorous bats hunt, they may encounter erratically...

... but the first (no pre-IPI) and last (no post-IPI) pulses. Patterning of IPIs was analyzed using two metrics. First, we identified ‘sonar sound groups’ or ‘strobe groups’ ( Moss et al., 2006 ; Petrites et al., 2009 ; Kothari et al., 2014 ), which are groups of pulses with short, stable IPIs surrounded...
