From: Barrier crossings and winds shape daily travel schedules and speeds of a flight generalist
Migration routes of lesser kestrels tracked with GPS between 2014 and 2019. (a) Post-breeding and (b) pre-breeding migration. Colours indicate nocturnal migration (blue segments) and diurnal migration (orange segments) when flying over non-barriers (grey) or barriers (desert =pink, sea = white). One position per hour was plotted.
