The primary purpose of this three week visit was to capture water and vagrant shrews (Sorex palustris and S. vagrans) and to ship them back to Baltimore by air. The shrews are now being used for two studies: one on aggressive behavior and communication with particular concern for whether acoustic or visual stimuli are involved; and another on echolocation discrimination of different textures, sizes and distances of objects. Project Number 172.
