This fourth ABLE zoo sound recording workshop took place at the San Diego Zoo where there is a wide variety of animals that vocalize. In general, at a zoo, aquarium, or farm, participants can record animals using the free downloadable Audacity or Raven Lite and convert these waveforms to spectrograms for further analysis. They can also record ambient noise and attempt to see if there are changes in the behavior of the animals under various conditions Hypotheses can be tested about how variable vocalizations might be in different settings; in a zoo-setting this could include a variety of other surrounding animals and humans. Are vocalizations different before, during, or after a feeding? For example, a St. Francis College student noted that sea lions became unusually quiet after a feeding session at the Queens Zoo in New York City. At the San Diego Zoo, participants can record birds, sea lions, and primates under various conditions.
