Today, I saw Azure-winged Magpies. I saw this bird when I was a kid. But recently, I hadn't seen this bird. So I'm glad that this bird is still living in Tokyo. It's wing is beautiful blue, and it's tail is very long. Japanese name of this bird is O-naga, which means long tail. Scientific name of this bird is Cyanopica cyana. According to Japanese Wikipedia, the bird had distributed entire Japan until 1970's. But after 1980's, it only distribute northeast region in Japan. So it disappered from west side of Japan within only 10 years. No one knows the reason. It's a mystery. This bird is omnivorous. In the first picture, the bird is eating something black. Although color of its wings are beautiful, its voice is not so beautiful.
