Ecology and Conservation of Galápagos Landbirds

• Host-Parasite Interactions
  We study the host-parasite relationship between the invasive parasitic Avian Vampire Fly (Philornis downsi) and Darwin’s finches. Our research focuses on how these finches adapt to this new parasite and how the parasite evolves in its new environment and host community.
• Conservation of Darwin’s Finches and the Little Vermillion Flycatcher
  We investigate the rapid decline of Darwin’s tree finches and the Little Vermillion Flycatcher, with a specific focus on the impacts of the invasive Avian Vampire Fly and the invasive Blackberry.

Animal Cognition

• Stress, Nutritional State & Behavioral Flexibility
  We study how both short-term and long-term stressors, as well as nutritional state, influence behavioral flexibility. Fish serve as our model species for this research.
• Behavioral Flexibility & Innovation
  We have developed an integrated framework for understanding animal innovation, which explores the interactions between mechanisms, fitness benefits, and evolutionary significance. Our work includes laboratory experiments that investigate innovativeness in both animals and humans.
• Tool Use
  We investigate tool use, applying Tinbergen’s four questions to address underlying cognitive mechanisms, development, and adaptive value. Using a comparative approach, we conduct both lab and field-based research. Our current model species are Darwin’s finches and Goffin’s cockatoos and children, in collaboration with Alice Auersperg.
