Differing migration patterns and year-round habitat-use of allopatric nesting Eastern Tundra Bean Geese ( Anser fabalis serrirostris ) in East Asia
Sympatric Chinese-wintering Eastern Tundra Bean Geese ( Anser fabalis serrirostris , ETBG) breed in two widely separated Arctic areas (Central Russian Arctic and Anadyr region); South Korean-wintering birds (Chaun-South Korea) breed in a third discrete area between these two.

Sympatric Chinese-wintering Eastern Tundra Bean Geese ( Anser fabalis serrirostris , ETBG) breed in two widely separated Arctic areas (Central Russian Arctic and Anadyr region); South Korean-wintering birds (Chaun-South Korea) breed in a third discrete area between these two. Such winter/summer segregation likely structures the population, potentially resulting in distinct migration patterns and habitat-use throughout the annual cycle. We tracked individuals using GPS-GSM transmitters from all three of these geographically discrete ETBG subpopulations to see whether this was the case, testing for differences in migration patterns, seasonal and diurnal habitat-use using remotely sensed land-cover mapping. Mean migration distance of Central Arctic-China and Chaun-South Korea individuals did not differ significantly, but Anadyr-China birds travelled 15–24% further (mean: 1140 km, P < 0.001). Despite this, mean spring migration durations were longest among Central Arctic-China ETBG, significantly longer than Anadyr-China geese, due to significantly longer stopovers, which were significantly longer than Chaun-South Korea birds.
