A Blue View: Studying Dolphin Behaviors

ABOUT THE STUDY
Enrichment provides opportunities to animals to become engaged in something that will hopefully be fulfilling for them. In the bubble sphere enrichment study, staff put together 10 different types of novel enrichment that the dolphins had not previously experienced. Each enrichment is presented to the dolphins in front of the glass four days in a row, and a video records the dolphins and the bubble spheres that are generated. Independent reviewers will look at the tapes and count the bubbles to see if there is a correlation to the number of bubble spheres and exposure to the enrichment.

The Chimp Parade has been one of the favorites so far. The hamster, chimp, and duck are robotic, and they all move when activated. The stars on the chimp’s springy headband have flashing LEDs, and there is a similar star on the back of the duck’s wagon. The vertical object behind the chimp with the silver pipe cleaners on the end and purple, green, and red ribbons is actually a large spring that sways when the skateboard moves.
