What is she up to? I am a behavioral ecologist using remote sensing to study marine mammals. I am specifically interested in understanding the relationships between behavior, environment, and individual characteristics including physiology, morphology, sex, age, and health. I have a background in studying marine megafauna using image analysis of drone data. For my PhD I used drone footage to study the behavioral ecology and respiration physiology of the Pacific Coast Feeding Group (PCFG) gray whales. For my postdoc, I am investigating the social behavior of gray whales on the PCFG foraging ground and in the wintering lagoons in Mexico where I’ll also assess the influence of close encounters with humans on their behavior.

Thesis: Movement ecology of Hawaiian false killer whales: Influence of the physical environment and social structure, with implications for management
What is she up to? I am a NSF GRFP Fellow at Oregon State University’s Marine Mammal Institute. Leading up to graduate school, I worked as a research assistant at Cascadia Research Collective, a non-profit organization conducting research on marine mammal populations off the US West Coast and Hawaiian Islands, and continue to collaborate with CRC on my thesis research. I’m broadly interested in how animals’ spatial and social environments shape their movement decisions across different scales. My dissertation explores these questions in Hawaiian false killer whales using long-term datasets on satellite tracking, social associations, and biomarkers in collaboration with Cascadia Research Collective (where I am also a Research Biologist). Though my dissertation is focused on false killer whales, I’m involved in a number of research initiatives on Hawaiian odontocetes, many of which use integrative approaches (telemetry, photo-identification, genetics, etc.) to inform conservation and management.

Kiera McGarvey Sears, MSc
2022, MSc student at University College Cork, Ireland
Institution: Oregon State University, USA
Co-supervisors: Dr. Mauricio Cantor, Prof. Emer Rogan, Prof. Fabio Daura-Jorge
Thesis: Parallel Lives: Do bottlenose dolphins cooperate amongst themselves when foraging with artisanal net-casting fishers?
Kiera successfully completed (and received first-class honors for) her MSc in August 2022!
What is she up to now? I am working as an aerial observer with the Florida Fish and Wildlife North Atlantic Right Whale team dedicated to tracking the reproduction success of these endangered whales. Before this I had just finished the last field season of Rebecca Dunlop and Mike Noad’s Hearing in Humpback whales Acoustic Research Collaboration (HHARC) a multi year project designed to assess the hearing levels of baleen whales through acoustic experimentation.
What was she up to? Kiera studied the fine-scale foraging coordination among bottlenose dolphins that interact with artisanal net-casting fishers in Laguna, southern Brazil, to investigate whether this foraging tactic represents a case of social predation for the dolphins. Kiera quantified the degree to which groups of dolphins coordinate their actions during their interactions with the artisanal fishers, by measuring the cohesion, heading, and breathing synchrony of dolphin groups of different sizes in aerial drone footage of the interaction. Kiera was a visiting MSc student from the University College Cork, carrying out her thesis at the Marine Mammal Institute, Oregon State University.
