Geese and
ducks |
Kasumiga-ura,
Hi-numa, and
neighboring lakes
and marshes
(Kita-ura and
Sugao-numa) |
These lakes and marshes, including Kasumiga-ura Lake, are the primary wintering sites of ducks and geese in Kanto region. In particular, paddy fields and meander scars that adjoin the Lake, as well as the Lake itself, constitute the only regular wintering sites for geese (Anser fabalis middendorffii) in Kanto region. Hi-numa, Kita-ura and Sugao-numa (marshes) also preserve a suitable environment for geese inhabitation, and the geese stop here irregularly. At Sugao-numa, around 100 Anser albifrons were counted in January 2000 during the wintering season.
[Kasumiga-ura]: Anser fabalis middendorffii, Anas platyrhynchos and Anas crecca.
[Kita-ura]: Aythya valisineria.
[Hi-numa]: Bucephala albeola, rare species, is sometimes observed.
[Sugao-numa]: Cygnus columbianus. |
