石垣島初記録のカンムリオウチュウ(動画あり)

石垣島で初記録となるカンムリオウチュウが現れました。強い風と雨の中、飛んでいる(飛ばされてくる?)虫を捕まえていました。オウチュウよりも体はひと回り大きく、がっしりとしていて、羽毛の光沢は太陽が出ていないにもかかわらず、かなり強い感じでした。

カンムリオウチュウは2000年に日本初記録として与那国島に飛来。以降、沖縄本島や本島周辺離島で数例が確認されています。

日本産オウチュウ属は、今回のカンムリオウチュウで3種コンプリート。国内未記録種のヒメオウチュウの飛来にも期待がかかります。

Hair-crested Drongo
Hair-crested Drongo

While at work, a message came in through our group chat: "Greater Racket-tailed Drongo confirmed." I fidgeted through the rest of my shift, then rushed to the spot two hours after the alert — and managed to find the bird in driving rain and wind!!

Thanks to 石垣島BIRD観察, the first to find it, my life list got a new entry. ^^

Hair-crested Drongo
Hair-crested Drongo

It was larger than Black Drongo and Ashy Drongo, and gave an impression of being more composed. Slightly wary of crows and Grey-faced Buzzards, it still perched at branch tips and caught insects blown in by the strong wind.

アカツクシガモ、ベニバト、ソリハシセイタカシギほか

昨年 に続き、今年もアカツクシガモが飛来しました。今季は2羽で警戒心が非常に強いです。

先日のベニバト は滞在10日になりました。天候が悪くて移動できないと思われます。

10月26日から滞在のソリハシセイタカシギ も逗留中。こちらも滞在10日になります。

After the harvest, many Oriental Turtle Doves gather in the paddies to pick up fallen grain — and on Ishigaki, there is almost always a Crimson Sunbird among them.

コハクチョウ飛来 アカガシラサギ越冬中

約2年ぶりにコハクチョウが飛来しました。前回は春になるまで滞在したけど、今回はいつまでいるのか。警戒心はほとんどないので、長逗留してくれるとうれしいですね。

カンムリワシの動きが繁殖期を前に活発になっています。鳴き交わす声や縄張り上空を飛翔する姿をよく目にするようになりました。

アカガシラサギは複数箇所で越冬中。草むらに入ると同化して見つけにくいです。

オオバンが11月に入り、一気に増えました。一昨年はオオノスリによく襲われていました。今季はチュウヒ、ハイイロチュウヒ、ハヤブサが滞在しているのでオオバンにとっては気の抜けない越冬になりそうです。

シギはアオアシシギやコアオアシシギ、セイタカシギ、ヒバリシギ、タシギ、タカブシギあたりが滞在中です。

今季初のオカヨシガモを確認。ダムにはキンクロハジロやヒドリガモも増えてきました。

月蝕と天王星蝕

月蝕と惑星蝕が同時に起きるのは442年ぶりだそうです。今回の惑星蝕は天王星でした。自宅のデッキでバーベキュをしながら家族で観望しました。^^

The lunar eclipse reached maximum at 7:59 p.m. The tiny point of light at lower left is Uranus.

5年連続の暗色型サシバ 出会いの多いカタグロトビ(動画あり)

2018年から石垣島で毎年、越冬している暗色型のサシバ が今年もやって来ました。最初の年は幼鳥だったので、今年で5歳になります。少しずつ警戒心が弱くなり、今年はかなり近くで観察できるようになりました。

2015年に石垣島に初めて現れて 以来、順調に繁殖を重ねていまや石垣島内のあちこちで見ることができるカタグロトビはついに、町中へも進出して来ました。この日は真栄里にあるマックスバリュ上空で2羽が連れ添って飛ぶのを確認。石垣市役所東側の荒地で餌取りしているのもよく見かけます。

変なジョウビタキ、ムジセッカ、アオジ

石垣島にも越冬組の小鳥が増えてきました。

そんな中、見つけた変なジョウビタキ。最初はオスの幼鳥が第1回冬羽に変わりつつあるのかと思いましたが、そうでもないようで、メスタイプの変な羽衣の個体という可能性も指摘されています。いずれにせよ興味深いジョウビタキでした。

川沿いの茂みにはムジセッカがそれなりの数でやってきているようでした。写真はなかなか撮れないですね。

シベリアアオジはサトウキビ畑に結構な数が潜んでいました。アオジっぽい個体も混じっていました。

Daurian Redstart
Daurian Redstart

I thought the area around the throat might be partway through changing to adult male plumage, but it looks as though feathers have been lost, exposing the black area beneath. Even so, the whitish feathering from above the eye toward the cheek area looks like a male's.

That said, when Daurian Redstarts transition from juvenile to first-winter plumage, male individuals apparently develop vivid orange feathers. This individual shows some orange in places, but is otherwise brown.

Daurian Redstart

The hindcrown and hindneck are a pale brownish buff, more like a female. A genuinely puzzling and intriguing individual.

Plain Leaf Warbler

A Pale-legged Leaf Warbler — I could hear several calling. One came up into view.

Black-faced Bunting

A female Black-faced Bunting. I could hear many calls coming from the sugarcane field, and after waiting a short while it came in very close.

The small birds fell silent when the rain started, but were active again once it stopped.

ハイイロガン、カンムリワシ幼鳥、オニアジサシほか

10日ほど前に現れたハイイロガン。現在石垣島には、ハイイロガンのほかにカリガネ、マガン、ヒシクイ、コハクチョウ、クロヅルと南の島らしくない鳥たちが滞在しています。

カンムリワシの幼鳥は今シーズン9個体目となりました。非常に活発な個体で、水田や採草地で獲物を捕まえていました。

数日前からオニアジサシも飛来。例年、しばらくは滞在しますが、越冬まではなかなかしないです。海岸には、メダイチドリやシロチドリ、コチドリ、ムナグロ、キアシシギ、アオアシシギ、キョウジョシギなどが数を増減させながら滞在中です。

今季3個体目のアカツクシガモ、長逗留のハイイロガン、夏羽のメダイチドリ(動画あり)

前回の成鳥2羽 に続き、今回は幼鳥のアカツクシガモが飛来しました。成鳥たちは警戒心がめちゃくちゃ強かったのですが、今回の幼鳥は若さゆえか警戒心はほとんどなく、楽に観察できました。

ハイイロガンも長逗留中でこのまま越冬モードでしょうか。ヒシクイ、マガン、カリガネ、クロヅルも滞在中です。

海岸にはメダイチドリやシロチドリ、ムナグロ、キョウジョシギ、アオアシシギ、ハマシギなどが少数ながらも滞在。田んぼではツルシギやセイタカシギ、タカブシギ、ヒバリシギ、ウズラシギ、タシギあたりが目立ちます。クロハラアジサシも成鳥、幼鳥とも滞在。

今シーズンはムクドリの仲間が種類はいますが数が少ないですね。

ツグミ、シロハラ、アカハラ、マミチャジナイも到着し出しました。

The third Ruddy Shelduck of the season was a juvenile — in the process of moulting from juvenile plumage into first breeding plumage.

The Greylag Goose, completely unafraid, is in the middle of a long stay. Does it intend to winter here?

The bird always accompanying the Greylag Goose is a Tundra Bean Goose. For some reason these two never join the flocks of Greater White-fronted Geese and Lesser White-fronted Geese.

バライロムクドリ幼鳥

11月中旬ごろからバライロムクドリが2カ所で現れています。きょうは自宅に近い方のバライロムクドリを見てきました。

日替わりでホシムクドリやギンムクドリの群れに混じって農地を巡っているようです。この日はムクドリ10羽ほどの群れに合流していました。仕事の移動中で観察時間15分ほど。

海岸には、キョウジョシギやキアシシギ、メダイチドリ、ムナグロ、トウネンなどが滞在していました。こちらも観察時間15分。最近、忙しくていけませんねぇ。
