久しぶりのジャワアカガシラサギ

10カ月ぶりにジャワアカガシラサギを確認。石垣島では、見る機会が増えている気がするなー。沖縄本島で昨年の10月に見た冬羽のジャワアカガシラサギ に比べると褐色味が強くアカガシラサギっぽくもあり微妙ですが、おそらくジャワアカガシラサギだと思われます。

ジャワアカガシラサギは警戒心もなく、田んぼでコサギやセイタカシギ、タカブシギなどと餌をとっていた。

p.s.

各所と検討の上、頸部の縦斑などから色のりのよいジャワアカガシラサギとします。

Javan Pond Heron

A Javan Pond Heron in winter plumage — subtle. The vertical streaking from the neck to the breast looks thinner than on Chinese Pond Heron.

It was catching small insects.

繁殖も終わりボロボロのリュウキュウアカショウビン

石垣島のリュウキュウアカショウビンは、繁殖もすっかり終えて換羽が始まりボロボロのみすぼらしい個体が増えてきました。

今日は、バンナ公園内のアカショウビンのポイントを数カ所回ってみると冬羽に換羽が始まった個体を数羽確認することができました。

今年生まれの幼鳥は成鳥と変わらないまでに成長しています。

Ruddy Kingfisher

A juvenile Ruddy Kingfisher that had caught a spotted cricket. It had plunged into a Chuetsu palm thicket to take it.

This individual has a darkened bill. The flight feathers and tail are worn to tatters, right down to the shafts.

It was hunting exclusively in low spots just a few tens of centimetres above the ground.

The claws are also visibly darkened. I wonder what condition it will be in at its wintering grounds.

Crested Serpent Eagle

I went along the forest road looking for Emerald Doves — there were about three, but they were all distant or hidden deep in the scrub with branches and leaves in the way. The usual Crested Serpent Eagle was perched at ease in a Chinaberry tree, waiting for prey.

ムラサキサギ2羽のヒナへ給餌

給餌間隔が非常に長いムラサキサギですが、やっと親鳥がヒナたちへ餌を与えているところを観察できました。

親鳥が西の方角から「グワァー」と鳴きながらやってくるとヒナたちは「グワッ、グワッ、グワッ、グワッ、グワッ」と早い調子でないて餌をもらっていました。親鳥の帰巣時の鳴き声もヒナたちの餌をねだる鳴き声もアオサギに似ています。

文献によると50日前後での巣立ちとのことなので、あと2週間ほどで巣立ちすることになるのでしょう。

ほかの観察者によると昨日から巣を離れて歩き出し、今日は巣の下の水場まで降りて水を飲んだり、浸かったりしていたそうです。

ちなみに今回、営巣を見つけたのは師匠でこの観察記録をもって日本鳥学会の最新版「日本鳥類目録第7版」で「石垣島では冬鳥」となっている記述が留鳥に書き換えられるとのことです。

The well-grown chicks beg from the parent with such intensity that the parent is desperately trying to dodge being stabbed by their bills.

ムラサキサギ子育て中

師匠に教えてもらったムラサキサギの営巣を見てきました。ムラサキサギの繁殖の詳細な記録はほとんどなく、貴重なものを見せてもらいました。

台風9号の影響が心配でしたが、無事にやり過ごしたようです。あと7週間程度で巣立ちでしょうか。

今季初のキセキレイ

今季初のキセキレイを2カ所で1羽ずつ確認。秋の渡りもここから加速していきます。

シギとチドリは、タカブシギ、アオアシシギ、コアオアシシギ、トウネン、タヒバリ、セイタカシギあたりが日替わりで入っていますが、数はまだまだ少なめです。

カンムリワシは子育てが終わった成鳥がちょこちょこ出るようになってきました。

Grey Wagtail

A Grey Wagtail that caught a small insect. The yellow on the undertail-coverts is vivid — first-summer plumage, perhaps.
