At Migrate Technology, we specialise in the design and manufacture of miniature archival light level geolocators (GLS) for tracking birds. These loggers record ambient sunlight over very long periods. From this recorded information, the areas that the animal visited can be determined using astronomy. This exciting low-cost
technology is being used successfully to track annual large-scale bird movements
such as migration. Seabirds, waders, wildfowl, passerines, land birds and seals are all being successfully tracked using geolocators. We welcome contact from researchers anywhere around the globe who wish to use standard devices or need bespoke logging requirements. We can help you decide if the technology can help answer your research questions, and offer advice on usage and analysis of data.
Please note that these are not online realtime tracking devices; presently, in order to see the data, tags must be retrieved to download the data archive. This necessitates animal recapture and, thus, site fidelity at wintering, breeding or stopover locations.
Recapturing animals in order to download the data recorded
on their geolocator tags enables loggers to be made much smaller than a satellite technology such as
PTT. Also, archival light level geolocators can be made far smaller than GPS recorders or those that have remote download capability. The accuracy of light level geolocation is appreciably less than GPS but is, with a suitable study species, enough to provide detailed timing and movement data as well as to identify important stopover areas relating to bird migration. The technology is cost effective enough that several geolocators can be bought for the cost of a single dedicated GPS logger.
