  represent dynamic sensory information from the natural environment?  How 
 are sensory signals and motor commands coordinated to direct actions in 3D
  space? The echolocating bat presents a powerful animal model to address t
 hese questions\, as it produces the very acoustic signals that guide its b
 ehaviors. Importantly\, the echolocating bat adapts its echolocation signa
 l design with changes in behavioral state\, providing an experimental wind
 ow to quantify on a millisecond time scale the information an animal has p
 rocessed and the information it is seeking. My talk will review a series o
 f experiments that probe the echolocating big brown bat’s sonar target t
 racking behaviors\, both in flight and from a stationary perch. These expe
 riments employed high-speed stereo IR video to reconstruct the bat’s fli
 ght trajectories and microphone array recordings to measure its sonar beam
  aim (acoustic gaze)\, as it steered around obstacles and prepared to inte
 rcept prey. Some experiments combined behavioral studies with neural telem
 etry recordings\, which revealed dynamic remapping of echo response areas 
 with shifts in the bat’s sonar-guided attention. Collectively\, results 
 from these experiments provide evidence that the echolocating big brown ba
 t 1) actively controls its acoustic gaze to inspect and track objects\, 2)
  couples its acoustic gaze and locomotor plan\, and 3) relies on internal 
 models of target motion to enable tracking under occlusion and to predict 
 its point of interception with prey. These findings show parallels with vi
 sual tracking in humans and other animals.
