Chicago Zoological Society's Dr. Lance Miller is one of the principle investigators of a recently published comprehensive Dolphin Welfare Study. Using new technology and software to track study animals, researchers examined physiological and behavioral metrics for dozens of cetaceans from more than 40 AMMPA and AZA accredited facilities across 4 continents to better understand the factors that contribute to improved animal welfare. Such factors include habitat size, access to environmental enrichment, training, age, guest interactions, and more.   That Sounds Wild: Hippos Animal Care Software KONG Zoo Zoo Logic ZOOmility
