カンムリワシのカップル

カンムリワシがサキシママダラと思われる大きなヘビを樹上で食っていました。オスのカンムリワシで、右足に「M」と刻まれた緑の足輪を装着していることから 2017年に衰弱しているところを保護された個体の「悠々」 です。

悠々がヘビを食っているとどこからかメスの鳴き声が聞こえてきます。見渡してもどこからか分からなかったのですが、しばらくすると悠々の止まる木の下の方からメスのカンムリワシが飛び出てきました。

メス個体の腹部の羽毛が乱れていることから抱卵中かと思ったのですが、メスは抱卵中は巣外に出ることはないそうなので、どうも繁殖に失敗した可能性があるようです。求愛給餌のような行動は、繁殖したペアが見せるそうです。

季節外れのキンクロハジロやすっかり夏羽のツメナガセキレイとツバメチドリ、ムナグロなどもいました。

6月8日追記

なんと、このカンムリワシのカップルはここで営巣していました!! 農道にかなり近く、貧弱な林の中に巣があったのでカンムリワシの調査をしている方も驚いていました。

After a while, Yūyū flew off to a nearby branch. The feathers are dirty with mud, but you can see the green leg ring on the right leg.

The Sakishima rat snake looked to be well over a metre long — a big one. After this, the female Crested Serpent Eagle disappeared back into the undergrowth with the prey.
