Heading south: a Cory’s Shearwater gets tracked after fledging for the first time

Raül Ramos (Departament de Biologia Evolutiva, Universitat de Barcelona, Spain) and colleagues have published in the journal Bird Study on the at-sea movements of a juvenile Cory’s Shearwater Calonectris borealis from the Canary Islands.

The paper’s abstract follows:

“Using geolocator-immersion loggers, we tracked for the first time the migration of one Cory’s Shearwater Calonectris borealis fledgling, from its breeding colony in the Canary Islands, and along its first year of life. The juvenile bird initially followed the same migratory path as the adults but visited different areas of the Central and the South Atlantic Ocean.”
