Dates of the onset of spring and the peak in nutrient biomass at each site against the flight distances.
Sites include wintering site (0), stopover sites (1–4) and the breeding site (5). Error bars indicate the median and range of the arrival time of 19 female Barnacle Geese derived from Eichhorn et al. (2006)38.
