Each year more than two billion songbirds cross the Sahara, but how they perform this formidable task is largely unknown. Using geolocation tracks from 27 pied flycatchers, a nocturnally migrating passerine, Janne Ouwehand and Christiaan Both show that most birds made diurnal flights in both autumn and spring. These diurnal flights were estimated to be part of non-stop flights of mostly 40–60 h. In spring, birds flew across the Sahara, while autumn migration probably circumpassed part of the desert, through a long oversea flight. Their data contradict claims that passerines cross the Sahara by intermittent flight and daytime resting. The frequent occurrence of long non-stop flights to cross the desert shows migrants' physiological abilities and poses the question why this would not be the general migration strategy to cross the Sahara.
Four researchers of the Faculty of Science and Engineering of the University of Groningen (the Netherlands) have received an ENW-XS grant from the Dutch Research Council (NWO). These grants are awarded to encourage curiosity-driven and bold...
EIC Pathfinder grants are intended to support research teams in investigating or developing an emerging breakthrough technology.
What is special about these grants is that they come under the Global Challenges & European Industrial Competitiveness branch of Horizon Europe. This means that the technological application has already been considered.
