Timing and duration of the migration and non-breeding areas in thin-billed prions from New Island, Falkland and Île Mayes, Kerguelen (means ± SD).

Significant p-values are marked bold. Dates are given as Julian date (i.e. 1 Jan = 1). Two thin-billed prions from New Island without long-distance migration were excluded from the analyses. In the analyses of outward migration, we included all successful breeders (N = 13 for Falkland and 17 for Kerguelen). In the analyses of outward migration, we included only individuals with a clearly distinguishable, directed return track (N = 31 for Falkland and 13 for Kerguelen).
