Effect of jamming on behavioural performance. (a) Landing rate in uncluttered room was not reduced by various jamming conditions and severities. Data for each bat was pooled and normalized such that the landing rate (number of landings per seconds flown) without jamming was designated as ‘1’ (values are mean ± s.d. for all bats). (b) Obstacle avoidance performance in a cluttered room was slightly reduced when bats were jammed. Data were pooled and normalized as in (a).
