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.

Great Crested Grebes were capturing fishes in large flocks

The Great Crested Grebes of Lake Sayama are acting in large flocks. I wonder how many birds are there.

I zoomed in on the image above and counted how many birds there were.

There are probably close to 400 birds of them.

The Great Crested Grebes are moving around the lake to capture fishes. When they start to dive all at once, you may not be able to see them from the surface of the lake.

See the video for more details.
