New research led by the BTO has used a combination of GPS-tracking and advanced statistics to provide new insights into seabird flight heights by night and day. This study gives important information on the risk of seabirds colliding with offshore wind turbines and at a time when governments worldwide are investing in offshore wind farms.

Population decline is linked to migration route in the Common Cuckoo, a long-distance nocturnally-migrating bird
Author: Hewson, C.M., Thorup, K., Pearce-Higgins, J.W. & Atkinson, P.W.
Published: 2016
When the BTO began ground-breaking Cuckoo tracking project in 2011, we had very little idea where these birds spent the winter or how they got there. Our latest research not only reveals this information, but also shows that Cuckoos’ use of autumn migration routes helps explain population declines.
