It is because autumn migratory birds are coming soon.
I can't stop going out for photographing of wild birds,
in spite of the low back pain.
However, migratory birds seem to have not yet come so far
today,
On my way home, I was able to see the battling of male
Japanese Pheasants.
もうそろそろ秋の渡り鳥が来る頃なので、腰痛ですが野鳥の写真を撮ろうと外に出ずには入れられません。しかし、今日は未だ来ていないようですが、帰り道でキジのバトルを見ることが出来ました。
It seems not to be a full-fledged struggle.
According to the Wikipedia Japanese
description,
Four subspecies due to geographical
variation were distributed in Japan, but the crossing between subspecies has
progressed by release birds and the difference is becoming obscure.
