Migration strategy and winter area use of common swift (Apus apus) breeding in the Netherlands – using combined GeoLight and FlightR approach
Migration is an adaptation for birds to exploit the resources that change temporally and spatially. The recent development of miniature light level geolocators has revealed this previously poorly known aspect of birds. From light intensity data together with time recorded by geolocators, we can infer the positions of the birds, i.e. latitudes and longitudes, using a threshold method or a curve-fit
