Birds of Tokyo people return to the Sumida River!
Did you know that the birds of the city are gulls?
Also, did you know that the gull is a "migratory bird"?
Miyakodori, the Miyakodori, which also became the name of the new transportation "Yurikamome", is actually a "migratory bird".
A bird from Tokyo who had left Japan in the summer has returned to the Sumida River this year.
This photo is a squirrel that I saw on the Sumida River at the end of October last week.
The Japanese gull is a migratory bird, leaving Japan in spring and returning to Japan in early winter.
It seems that summer is the breeding season, so it basically does not nest in Japan.

There are several types of seagull in Japan. Do you know how to distinguish Japanese gulls?
It is characterized by red beaks and red feet.
In fact, both the photo on the right and the photo on the left are blackheads.
It looks a little different, even though it looks like a little different!
In Japan, the black gull over winter becomes black in spring, as shown in the photo on the right.
It's a sign to leave Japan when your head turns black.
On the other hand, as shown in the photo on the left, the head of a Japanese gull visiting Japan in early winter is white,
It is characterized by the appearance of black spots from the eye to the back of the head.
I felt that winter had come again this year due to the arrival of the Japanese gull.
