Navigation and Orientation

How animals are able to navigate over such large distances each year has fascinated biologists for centuries. Part of the research in Norris lab focuses on understanding the proximate mechanisms birds and butterflies use to migrate between their breeding and non-breeding grounds. We have and are undertaking a series of translocations experiments  designed to examine how individuals are able to detect longitudinal displacements.
