  • IPI, interpause interval; pbP, post-buzz pause.

    c, capture; t, touch; w, wide.

    Values for search signals are also given for the pooled data.

    Values are means ± S.D. N for individual bats: Bat B: 80 c, 16 t, 28 w; Bat S: 80 c, 31 t, 44 w; Bat S: 80 c, 24 t, 42 w; N for all bats: 240 c, 71 t, 114 w.
