Notes
The GLS data were generated using FlightR and are estimated means of lat and lon. I can supply confidence intervals for these data as well as median estimates for lat and lon. FlightR enables estimates during the equinoxes so I have included equinox periods in the data. All tracked birds are adult breeders, but the data is from the non-breeding/wintering period only i.e. from the day they leave the colony until their return.
