Inter-annual comparison of the outward and return migration in thin-billed prions (means ± SD) from New Island, Falkland Islands.

Significant p-values are marked bold. Homogenous subsets in statistically significant comparisons are marked with the same superscript letter (a or b). Dates are given as Julian date (i.e. 1 Jan = 1). In the analyses of outward migration, we included only successful breeders (N2010 = 6, N2011 = 7). Nonbreeding area: N2010 = 19, N2011 = 13, N2013 = 7, Return migration: N2010 = 15, N2011 = 11, N2013 = 5.
