Ducks in the pond
Many ducks came back from the north to the pond called Oike near my house.
Today I found black birds whose name I don't know there.
I've never seen them till today.
I wonder what the name of this bird is !
Black bird
These female three ducks don't fly to the north even in summer but live this pond all year round.
Sleeping ducks
Aigamos eat weeds ,insects and cultivate soil.
After harvest, my friend brought five or six Aigamos to Oike pond few
years ago.
Black duck you can see are their survivors.
So I wonder whether they are Aigamo or cormorant.
It may be moorhen as you say.
