Ground breaking insights on swift migration

A newly published paper in Current Biology by Anders Hedenström et al. reveals that common swifts stay airborne for 10 months without landing - a world record.
Swift flight

Using micro data loggers with an accelerometer to record flight activity and light-level sensors for geolocation – the research group (Anders Hedenström, Gabriel Norevik, Kajsa Warfvinge, Arne Andersson, Johan Bäckman och Susanne Åkesson) showed that swifts are airborne for almost the entire time during their 10-month non-breeding period; some individuals never settled, but occasional events of flight inactivity occurred in most individuals.
