“…This shows that Greylag Geese can complete this entire migration in one leg, implying the ability to accumulate all the necessary energy stores before undertaking the journey without stopovers (Smith et al 1986). These findings corresponded to empirical findings that most migratory birds travel faster in spring than autumn because long-distance migrants are more time-limited during spring migration (Shimada et al 2016). Theory predicts that competition for best breeding sites might be the dominant driver for arrival earliest at limited breeding sites, which suggests that migrants should adopt the time minimization strategy during spring migration to arrive as early as possible in the best possible condition at breeding sites (Kokko 1999).…”

Twenty Far East Greylag Geese, Anser anser rubrirostris, were captured and fitted with Global Positioning System/Global System for Mobile Communications (GPS/GSM) loggers to identify breeding and wintering areas, migration routes and stopover sites. Telemetry data for the first time showed linkages between their Yangtze River wintering areas, stopover sites in northeastern China, and breeding/molting grounds in eastern Mongolia and northeast China. ). The median stopover duration was 31.1 and 51.3 days and the median speed of travel was 62.6 and 47.9 km/day for spring and autumn migration, respectively. The significant differences between spring and autumn migration on the migration duration, the stopover duration and the migration speed confirmed that tagged adult Greylag Geese traveled faster in spring than autumn, supporting the hypothesis that they should be more time-limited during spring migration.

“…Movements between Notsuke Bay and Kunashiri Island were greater during spring than autumn which were consistent with the northward direction of the migration path during that season. As spring progressed, there was increased movement to Kunashiri Island, suggesting this site is strategic for timing northward migration across the Sea of Okhotsk and arrival along its northern coast as a stopover area (Shimada et al, 2016;Sawa et al, 2020a).…”

“…Tracking studies have revealed that some individuals migrating from Notsuke Bay in autumn pass through Kunashiri Island, Furen Lake, and Biwase/Akkeshi Bay to more southerly wintering grounds (Sawa et al, 2020a). During spring migration, many of the birds that wintered in Japan return to Notsuke Bay and Kunashiri Island before heading north across the Sea of Okhotsk (Shimada et al, 2016;Sawa et al, 2020a). Coastal marine habitats of eastern Hokkaido serve as important stopover sites for the migration of the Brent Goose during autumn and spring.…”

Nearly the entire (98%) and over a third of the East Asian population of Brent Geese stage in Notsuke Bay and nearby sites of eastern Hokkaido, Japan, during autumn and spring migration, respectively,. Despite the region’s importance as a refueling site for migrating Brent Geese, little is known about how these migrants use specific sites within this region. In this study, we investigated the seasonal variation in the movements and use of four key sites in the eastern Hokkaido using radio telemetry. Notsuke Bay was the primary staging area for Brent Goose in both seasons, but there were frequent movements between Furen Lake in fall and between Kunashiri Island in spring. The three sites lie in close proximity to one another in the Nemuro Strait, enabling relatively quick (<30 minutes) flights between sites. Consequently, these sites may be considered as one continuous habitat during migration. Brent Geese primarily foraged on eelgrass beds at night in fall and during the day in the spring. The occupancy rates of marked geese within the protected areas of Notsuke Bay and Furen Lake were 74% and 71% during autumn, and 64% and 87% during spring, respectively. However, extending the buffer to 3 km from the boundaries of the protected areas resulted in residency rates exceeding 90% during both seasons. To effectively conserve these important staging sites in the Nemuro Strait, we recommend expanding the protected areas and including connecting waters between Notsuke Bay and Kunashiri Island and Furen Lake.
