November's Birder's Night - Wandering the Earth with Nomadic finches: Lessons Learned About Flexible Migrations
Birds are the harbingers of spring as migrants move north and begin singing.
We know how swallows, swifts and some other migrants seem to go from one
fixed territory to another, annually. These north-south waves of billions of birds
are familiar to most people but there are many birds for whom north-south is
not always the way. Nomadic and irruptive species live lives of flexibility -
responding to less predictable fluctuations in food that can vary in timing or
location. How do these birds cope with such uncertainty? What strategies in
behavior or physiology do they have to survive when things go wrong? Dr.
Jamie Cornelius will share some of what she’s learned about life as a wanderer
from members of the finch family--red crossbills, pine siskins, goldfinches, zebra
finches and more.

Dr. Cornelius is an Assistant Professor of Integrative Biology at Oregon State University. After earning her PhD at University of California Davis she spent time at research institutions around the world, including the Max Planck Institute of Ornithology in Germany, St. Petersburg University in Russia, and the Organization for Tropical Studies in Costa Rica. She currently studies how birds adapt to unpredictable changes in the environment, including during food shortages, storms, and predation.
