日本の留鳥だがあまり見かけないアオバト, White-bellied green pigeon, which is a Japanese resident bird but rarely seen.
公園の森の所で数人の「とりびと」が望遠レンズを木の枝の方向に向けていた。近寄ってみると、緑の木の葉に囲まれた枝に1羽のアオバトが 止まっていた。話を聞くと、最近朝の比較的早い時刻にアオバトが出るとのことだった。この日には前回（12/21）より1時間ほど早く森に着いたので、 アオバトの出る時刻に合ったらしい。
In the woods of the park, several birders pointed their telephoto lenses toward the branch of a tree. As I approached, a White-bellied green pigeon was perched on a branch surrounded by green leaves. When I heard the story, they said that the green pigeon appeared relatively early in the morning recently. On this day, I arrived at the forest about an hour earlier than last time (Oct. 21), so it seems that it was time for the green pigeon to appear.
アオバトは枝に止まったままあまり動かない。緑の木の葉に囲まれた枝に止まって動かなければ保護色で見つけるのは難しい。 肩から羽の一部が暗赤色に見えるのでこのアオバトはオスだろう。 以前、秋ヶ瀬公園でもアオバトを見たことがある。
The green pigeon stays on a branch and does not move much. If the pigeon does not move on a branch surrounded by green leaves, it is difficult to find because of its protective color. This green pigeon is probably a male because part of its wings appears dark red from its shoulders. I have seen green pigeons in Akigase Park before.
