今日は土曜日で駐車場に車が多く撮影できないため少し崖の上まで登って撮影した。

14:40 中央崖の上に１羽確認、すぐにもう１羽が戻ってきて中央左の崖の上に留まった。
- One individual was observed on the central cliff; shortly thereafter, the second individual returned and perched on the left side of the central cliff.

まとめ (Summary)
今日は午後から短時間の観察。時期的に交尾のシーンが見られるかと期待していたがその様な行動、活動もなく早く撤収した。次回に期待したい。
- Today’s observation was conducted briefly in the afternoon. Although I had expected the possibility of observing courtship or copulatory behavior at this time of year, no such activity was recorded, and the session was concluded early. I look forward to the next observation.
