Birding In Taiwan
The
former breeding range of the
Swan Goose
(the ancestor of
the domesticated “Chinese Goose”) extended widely across eastern
Siberia into northern China and Mongolia, but the present
breeding range is severely fragmented. Swan Goose numbers have
been in decline since the beginning of the year 1900. The
remaining population (perhaps only 300–400 pairs) breeds
primarily in steppe and forested steppe marshes and lakesides of
eastern Siberia. The former wintering range included
Korea, Japan and a large part of eastern China; now it is
regular only in a smaller area of eastern China.
Swan Goose is listed as
Endangered
on the
2006 IUCN* Red
List
(as evaluated by BirdLife International) because its
population is declining very rapidly as a result of habitat
loss, particularly to agricultural development, and
unsustainable levels of hunting.
