Skagit Audubon Society is pleased to host Dr. Alejandro Rico-Guevara on Tuesday, Sept. 14 at 7pm (PST) for a fascinating virtual presentation titled "To Feed or to Fight? Behavioral Ecophysics of Hummingbirds".
Energetically constrained animals have evolved adaptations to enhance caloric intake. On the other hand, animal competition sometimes turns into physical combat, and particular weaponry evolves. Dr. Rico-Guevara will present findings on each of these fronts, along with a case study of hummingbird bill weapons. These discoveries revive questions about how these birds budget energy gain and expenditure to enable hovering, the most expensive form of locomotion, establishing coevolutionary relationships with the plants they pollinate.
Dr. Rico-Guevara is an Assistant Professor at the University of Washington and the Curator of Ornithology at the Burke Museum. He attended Universidad Nacional de Columbia as an undergraduate and received his PhD from the University of Connecticut as a Fulbright Scholar. He carried out postdoctoral research as a Miller Fellow at UC Berkeley and received the Pitelka Award for excellence in research from the International Society for Behavioral Ecology. His research has been featured by the NY Times, National Geographic Magazine, and in six different nature documentaries/TV series, in addition to articles in numerous peer-reviewed publications.
