Notes
Data from: Krietsch J, Hahn S, Kopp M, Phillips RA, Peter HU, Lisovski S (2017) Consistent variation in individual migration strategies of brown skuas. Mar Ecol Prog Ser 578:213-225. https://doi.org/10.3354/meps11932
Shared locations refer to the most likely locations (see Methods). Equinox periods (assigned in data) should be removed for further analysis. Three individuals were hybrids of brown skua and south polar skua (EA 108272, EA 127245, EA 156143). 9 tracks include a
pre-laying exodus (birds arrived in the breeding ground, but left again) back in the wintering distribution.
