                <description>Many migrating herbivores rely on plant biomass to fuel their life
                    cycles and have adapted to following changes in plant quality through time. The
                    green wave hypothesis predicts that herbivorous waterfowl will follow the wave
                    of food availability and quality during their spring migration. However, testing
                    this hypothesis is hampered by the large geographical range these birds cover.
                    The satellite-derived normalized difference vegetation index (NDVI) time series
                    is an ideal proxy indicator for the development of plant biomass and quality
                    across a broad spatial area. A derived index, the green wave index (GWI), has
                    been successfully used to link altitudinal and latitudinal migration of mammals
                    to spatio-temporal variations in food quality and quantity. To date, this index
                    has not been used to test the green wave hypothesis for individual avian
                    herbivores. Here, we use the satellite-derived GWI to examine the green wave
                    hypothesis with respect to GPS-tracked individual barnacle geese from three
                    flyway populations (Russian n = 12, Svalbard n = 8, and Greenland n = 7). Data
                    were collected over three years (2008–2010). Our results showed that the Russian
                    and Svalbard barnacle geese followed the middle stage of the green wave (GWI
                    40–60%), while the Greenland geese followed an earlier stage (GWI 20–40%).
                    Despite these differences among geese populations, the phase of vegetation
                    greenness encountered by the GPS-tracked geese was close to the 50% GWI (i.e.
                    the assumed date of peak nitrogen concentration), thereby implying that barnacle
                    geese track high quality food during their spring migration. To our knowledge,
                    this is the first time that the migration of individual avian herbivores has
                    been successfully studied with respect to vegetation phenology using the
                    satellite-derived GWI. Our results offer further support for the green wave
                    hypothesis applying to long-distance migrants on a larger scale.</description>
