patterns of Far East Greylag Geese (Anser anser rubrirostris) revealed
by GPS tracking. Integrative zoology, 15(3), pp.213-223. (»ÒÑ㣬26g)
¡¡¡¡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. 10 of the 20 tagged
individuals provided sufficient data. They stopped on migration at the
Yellow River Estuary, Beidagang Reservoir and Xar Moron River,
confirming these areas as being important stopover sites for this
population. The median spring migration duration was 33.7 days
(individuals started migrating between 25 February and 16 March and
completed migrating from 1 to 9 April) compared to 52.7 days in autumn
(26 September¨C13 October until 4 November¨C11 December). 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.
