Mandarin ducks are occasionally observed in our area. In the fall, the mandarin ducks are on migration. On October 4, we saw two mandarin ducks 4 km downstream from here. Those images are shown below. The one on the right is
a male because of its red beak. This individual is an eclipse. On the left, it is hard to distinguish whether it is a young bird or a female. Now these birds are not there.
This brings us to the main topic. One male mandarin duck was with a group of spot-billed ducks on October 17. It was swimming around with these.
Then, to our surprise, he began courting them. He quickly raised his head.
Then he lowered his head. He repeated the same behaviors.
The mandarin duck tried to approach the spot-billed ducks, but they were running away from him. Still, the mandarin duck did not flinch.

The chick was incubating the egg while the parents were away from the nest. The chick was 6 or 7 days old. We once observed children incubating eggs on June 7, 2021 (See website.). Only one of the three chicks incubated the egg. We would like to know the sex of the chick, but it was not possible. Unfortunately, this egg did not hatch.
It is too early to conclude from this observation alone that the chicks will incubate the eggs. More observations are needed. The following site showed the other chick incubating the eggs (website).

The little grebe lay eggs for the second time this year at the mouth of the Moro River. The male and female take turns warming their eggs. The floating nest must be constantly piled with fallen leaves or it will submerge. We hope the eggs hatch safely.
It is commonly known as “hammerhead flatworms”, “hammerhead worms” or “broadhead planarians” . When I exited the gate, there was something crawling along the road. It standed out because of its yellow color. I see it once or twice a year. I wonder where they are usually. The shape of the head is distinctive.
It was long and slender, so I measured its length. It was approximately 19.3 inches.
