| contents | (Uploaded by Plazi for the Bat Literature Project) Three-dimensional directivity patterns of sonar sounds emitted by Japanese house bats (Pipistrellus abramus) during natural foraging were measured by a 44-channel microphone array. Just before prey capture, the terminal frequency (TF) of emitted sounds decreased, and the beam width (mean 6 standard deviation) expanded from 40 6 10 to 63 6 9 (horizontal) and from 32 6 10 to 52 6 7 (vertical). P. abramus decrease the TF to simultaneously expand the beam width in both the horizontal and vertical planes, while retaining the target within the threedimensional acoustic field of view at the final stage of capture. |
