Spot-billed duck,カルガモ

According to the description of Wikipedia Japanese language,

Spot-billed duck is inhabited in the People's Republic of China, Japan, the Amur region, and the Korean Peninsula. In Japan, as a resident bird, it mainly inhabits south of Honshu.

Every year, you can see cute spot-billed duck chicks that were hatched near the water lily pond of a private residence near my house.
