Ring recovery
Migratory connections based on ring recoveries and
leg-flag
sightings in eastern Jiangsu are presented in Table 1. Some dunlin
individuals staging in Jiangsu came from Chukchi and Kamchatka
peninsulas, Sakhalin Island, Yalujiang Estuary, South Korea, Chongming
Island, Taiwan, Hong Kong, Beibu Gulf, and Leizhou Bay. The ring
recoveries produced a rough migratory map that showed dunlin breeding in
the Far East of Russia migrated through the Yalujiang Estuary, Jiangsu,
and Chongming Island to winter in southern China (Supporting information
Fig. S1). The numbers of ring recoveries from Kamchatka Peninsula and
Sakhalin Island were greater than those from other locations. However,
there were no resightings that indicated dunlins migrated from breeding
areas in Alaska or the west of Russia.
