A third of British Swifts have been lost since 1995, but the reasons underpinning this decline are unclear.
BTO scientists are involved in a project aiming to address these knowledge gaps. Tiny geolocators were fitted to adult Swifts captured at the nest in summer 2010 and retrieved in summer 2011 when these birds returned to breed. The results of this work are revealing the migration routes and important wintering areas for this species, which could help to identify key areas for Swift conservation.
