| dominant glint based prey localization in horseshoe bats: a possible strategy for noise rejection. | rhinolophidae or horseshoe bats emit long and narrowband calls. fluttering insect prey generates echoes in which amplitude and frequency shifts are present, i.e. glints. these glints are reliable cues about the presence of prey and also encode certain properties of the prey. in this paper, we propose that these glints, i.e. the dominant glints, are also reliable signals upon which to base prey localization. in contrast to the spectral cues used by many other bats, the localization cues in rhinol ... | 2011 | 22144876 |
| sensorimotor model of obstacle avoidance in echolocating bats. | bat echolocation is an ability consisting of many subtasks such as navigation, prey detection and object recognition. understanding the echolocation capabilities of bats comes down to isolating the minimal set of acoustic cues needed to complete each task. for some tasks, the minimal cues have already been identified. however, while a number of possible cues have been suggested, little is known about the minimal cues supporting obstacle avoidance in echolocating bats. in this paper, we propose t ... | 2015 | 26502063 |
