Students Explore Sounds and Behaviors of Dolphins
Seven Manhattan students embarked on a two-week Study Abroad trip to the Bahamas to discover and research the behaviors of wild dolphins.
“You always hear how smart dolphins are, but to observe them up close and actually see them doing these things without anyone training them, to do it was amazing.”
These were the words psychology major Cara Teri ’18 used to describe a recent trip to Bimini, Bahamas, to study sensation and perception while conducting research on wild dolphins.
Teri, along with six fellow Manhattan College classmates led by Maria Maust-Mohl, Ph.D., assistant professor of psychology, embarked on a trip to explore and research the behavior and communication of dolphins. A team from Hunter College accompanied the Manhattan group including Daisy Kaplan, Ph.D., instructor of psychology, and Diana Reiss, Ph.D., professor of psychology and nine students. Kaplan is also an adjunct instructor of biology at Manhattan College.
Prior to the trip, the students participated in a workshop to prepare for the fieldwork, and they received additional training in Bimini to introduce them to the study of dolphins. In partnership with the Dolphin Communication Project, an organization established in 2003 that encourages “the scientific study of dolphins with emphasis into understanding their behavior, acoustics, communication, cognition, ecology and more,” the faculty and students collected data for two weeks.
“I was surprised to learn that a dolphin slapping its tail meant that they were angry,” says Shea-Lynn Prendergast ’17, a psychology major.
Discovering the Voices of Dolphins
Led by animal expert Maust-Mohl, who has previously studied the behavior and communication of hippopotamuses, giraffes and dolphins, the three-credit PSYC 367 course included 14 days of study and observation of the dolphins in the water. The Bahamian wild dolphin population is familiar and acclimated to humans, which allows observers to study them in their natural habitat.
Led by Kaplan, the Hunter College undergraduates and graduate students are enrolled in a summer Animal Behavior and Conservation course.
The students went out on daily boat trips to observe the dolphins while snorkeling and on the water’s surface from the boat. In addition to attending frequent lectures organized by the professors, the students captured photos of the various dolphins, observed dolphin behavior, and recorded environmental data and information about dolphin sightings.
“In less than half an hour, we had our first of four dolphin sightings,” said psychology major Madison Bailey ’17, during their first day in Bimini. “Watching from the boat as the dolphins rode the bow was an experience that would put any Sea World trip to shame.”
Maust-Mohl remarked that “we were fortunate to see spotted and/or bottlenose dolphins almost every boat trip, where students were involved in observations both from the boat and in the water.”
During the trip, the students also saw sea turtles, fish, stingrays and sharks. In fact, the group visited the Bimini Shark Lab and learned about several research projects studying local shark species.
“I was also very surprised when a dolphin echolocated on my foot,” Teri explains. “I just recently had foot surgery and had metal screws put in, and the dolphin actually knew that there was metal in there and came to check it out.”
Since returning to New York in late July, the Manhattan team will meet to discuss their overall experience and observations and submit a final proposal later this summer. The proposal is a culmination of the course, and will allow the students to reflect on their experience and propose a project based on their observations.
“After all they have learned about dolphin behavior, communication, intelligence and conservation, it seems like the students have a very different perspective and respect for dolphins,” Maust-Mohl adds. “I feel very fortunate to have had the opportunity to share this experience with the students.”
Bailey will work directly with Maust-Mohl this fall on a research project to analyze the data collected including video and sound recordings. Maust-Mohl will determine next steps based on research goals that are part of the collaboration with Kaplan and other researchers. The continued work will contribute to ongoing research on the behavior and communication of spotted and bottlenose dolphins.
