Appropriate for migratory studies to investigate stopover places and timing, migration routes, wintering areas or non-breeding locations.
Geolocators require reasonable exposure to daylight which is important when considering whether this method is appropriate for your species. For example, when individuals use dark cavities or areas with heavy canopy, the light data gets erratic and this can be very difficult and sometimes impossible to analyse. This may only happen in periods when you do not need to know their location, e.g. birds breeding in nestboxes in the season when you can catch them, may not use cavities when they are on non-breeding grounds. Another time when light tends to get blocked, and frustrate geolocation, is when they incubate eggs and sit on legs that have geolocators.
