Species
Arctic Tern (Sterna paradisaea)
Device Type
Geolocator (GLS)
Notes
GLS locations of Arctic Tern pairs (female, male in that order from first birdID in dataset) tagged on Farne Islands in 2017 and recovered in 2018. Data are median coordinates at each threshold calculated by FLightR. Mean coordinates are in a separate database file. Note that Antarctic latitudes that cannot be estimated by FLightR are given as -66.56 representing the Antarctic Circle, and longitudes at these positions were estimated by a curve fitting procedure to calculate the time of midnight from light-level profiles.
