Ghosts That We Knew: Responses to Unfamiliar and Familiar Alarm Calls by Hawaiian Native and Nonnative Birds

AOS Student Research Grant Seminar

Presenter: Jonah Dominguez, Ph.D. candidate, University of Illinois at Urbana-Champaign University; AOS 2024 Student Research Grant winner

Birds can respond to the alarm calls of heterospecifics, though this is primarily documented in species engaging in mixed-species flocks. In Hawaiʻi, using the alarm call of native species and species that invasive species evolved alongside but no longer experience, we tested whether this alarm call response is the result of learned experiences, evolutionary history, or acoustic components of the alarm calls.
