Roslyn Dakin

Roslyn Dakin is a postdoctoral fellow with the Smithsonian Conservation Biology Institute’s Migratory Bird Center. The goal of her research is to understand how the physiological mechanisms that drive behavior evolve, and how this allows organisms to respond to diverse challenges in nature. To this end, she develops high-throughput behavioral assays that can be linked experimentally to physiology at the biomechanical, neurological, endocrine and molecular levels. At SCBI, Dakin works with Brandt Ryder to study the social behavior of wire-tailed manakins. This work leverages Ryder’s proximity logging system to track the movements of an entire population of manakins during their cooperative courtship displays in Ecuador, to understand the factors that promote cooperation.
