Eastern marsh harrier:チュウヒ

There used to be an RV car named Harrier, but it is the English name of the Eastern Marsh Harrier.

As you know, the Hen harrier (Northern harrier) is also a member of the circinate,very popular among bird photographer in Japan

In Eastern marsh harrier, about three types are observed: normal coat color all brown, white head, and blackhead, but in Japan, the white head is called zusiro, and black is called zuguro.

Zusiro's zu means head in Japanese, and siro means white. Similarly, zuguro's guro means black

I'm not an expert in this field, so I don't know why each coat color is different.

Another name for Zuguro in Japan is Tairikugata tyuhi, which means the continental type of strain marsh harrier in English.
